Side Plank Variations for a Stronger Core: A Key Exercise for Runners, Golfers and Athletes

You may be able to hold a regular plank—but can your core keep you stable when your body is loaded from one side?

That is where the side plank becomes especially valuable.

Running, golfing, skiing, cycling, lifting, and field sports rarely challenge your body in a perfectly symmetrical position. One leg accepts your weight. Your torso rotates. Your arms and legs generate force in different directions.

Your core must keep your spine and pelvis controlled through all of it.

Side planks train your body to resist unwanted side-bending and rotation while strengthening the muscles that connect your ribs, spine, pelvis, hips, and shoulders.

In this video, Dr. Joe demonstrates the traditional side plank along with several variations that can make the exercise easier, harder, or more specific to your athletic goals.

As you follow along, focus on maintaining a straight, controlled position rather than simply trying to hold the exercise for as long as possible.

Your set should end when your hips begin to drop, your torso rotates, or your shoulder can no longer maintain a comfortable position.

What Is a Side Plank?

A side plank is an isometric core exercise performed while supporting the body on one forearm or hand and the side of one or both feet.

Unlike exercises that repeatedly bend or twist the spine, the side plank asks your core to resist movement.

During the exercise, your muscles work to prevent:

• Your hips from dropping toward the floor

• Your spine from bending sideways

• Your torso from rotating forward or backward

• Your pelvis from rolling

• Your supporting shoulder from collapsing

This ability to resist unwanted movement is important during sports, lifting, walking, running, and daily activities.

What Muscles Do Side Planks Work?

Side planks involve much more than the abdominal muscles.

They commonly challenge the:

• Internal and external obliques

• Transverse abdominis

• Quadratus lumborum

• Gluteus medius

• Gluteus minimus

• Hip abductors

• Latissimus dorsi

• Shoulder stabilizers

• Rotator cuff

• Serratus anterior

• Spinal stabilizers

The supporting shoulder, trunk, pelvis, and hips must work together to keep the body aligned.

That makes the side plank a useful full-body stability exercise rather than an isolated abdominal movement.

Why Are Side Planks Good for Runners?

Running repeatedly places the body on one leg at a time.

Each time your foot contacts the ground, your trunk and pelvis must remain controlled while force travels through the leg and into the rest of the body.

If your lateral core and hip muscles fatigue, you may notice:

• The pelvis dropping on one side

• The trunk leaning excessively

• The knee moving inward

• A shorter or less efficient stride

• Increased side-to-side movement

• Hip or lower-back fatigue

• Difficulty maintaining form late in a run

Side planks can help runners train the muscles that resist these unwanted movements.

They may be particularly useful for trail runners, who must manage uneven ground, rapid direction changes, climbs, descents, and unpredictable foot placement.

Can Side Planks Help Prevent Running Injuries?

No single exercise can guarantee injury prevention.

However, side planks may help improve trunk and lateral hip control, which are important components of running mechanics.

Running injuries are influenced by many factors, including:

• Training volume

• Sudden mileage increases

• Running surface

• Footwear

• Sleep and recovery

• Strength

• Mobility

• Previous injury

• Running mechanics

• Tissue capacity

Side planks are best used as one part of a complete running-strength program that also includes calf strength, single-leg control, hip strength, and progressive exposure to running.

Why Are Side Planks Useful for Golfers?

Golf requires the body to rotate rapidly while maintaining posture and balance.

During the backswing, downswing, and follow-through, the trunk must transfer force between the lower and upper body without collapsing sideways.

Side planks may help golfers develop:

• Lateral trunk strength

• Rotational control

• Pelvic stability

• Shoulder stability

• Better control of golf posture

• Improved force transfer

• Greater endurance throughout a round

A side plank does not reproduce the golf swing, but it trains the ability to resist side-bending while the body creates and controls rotational force.

That can be valuable for golfers who experience lower-back fatigue or difficulty maintaining posture late in the round.

Can Side Planks Improve Golf Performance?

Side planks may support golf performance by improving trunk stability and endurance.

However, clubhead speed, consistency, and distance also depend on:

• Swing mechanics

• Hip mobility

• Thoracic rotation

• Lower-body strength

• Rotational power

• Balance

• Sequencing

• Practice and coaching

The side plank builds a foundation. Golfers must still learn how to use that stability during the swing.

What Other Athletes Benefit From Side Planks?

Skiers and Snowboarders

Skiing and snowboarding require the trunk to remain stable while the legs move independently beneath the body.

Side planks may help improve lateral trunk control and the ability to manage uneven terrain, turns, and changing forces.

Cyclists and Mountain Bikers

Cyclists need enough core endurance to maintain their position without placing excessive stress on the hands, shoulders, neck, or lower back.

Mountain bikers face additional demands from bumps, corners, drops, and rapid changes in body position.

Soccer Players

Soccer athletes repeatedly sprint, cut, kick, absorb contact, and balance on one leg.

Side planks can help train the lateral core and hip stability needed during these movements.

Tennis and Pickleball Players

Racquet sports involve repeated rotation, lateral movement, serving, reaching, and rapid changes in direction.

The side plank can help athletes resist unwanted trunk movement while generating force through the hips and shoulders.

Swimmers

Swimmers require trunk control to maintain body position while the shoulders and hips rotate.

Side-plank variations can also challenge shoulder stability, which may be useful when appropriately programmed.

Climbers

Climbers frequently create tension between one arm and the opposite leg.

Side planks can improve the lateral trunk and shoulder stability needed to maintain body position on the wall.

Hockey Players

Skating, shooting, checking, and changing direction all require control through the hips, pelvis, and trunk.

Side planks may support the ability to transfer force while resisting lateral collapse.

Lifters and CrossFit Athletes

Squats, deadlifts, carries, Olympic lifts, and overhead movements require the core to resist unwanted movement under load.

Side planks provide a simple way to build lateral trunk endurance without requiring heavy equipment.

How to Perform a Basic Side Plank

Lie on your side with your elbow positioned underneath your shoulder.

Stack your legs with your feet together, or place the top foot slightly in front of the bottom foot for greater balance.

From this position:

1. Press your forearm into the floor.

2. Lift your hips away from the ground.

3. Create a straight line from your head through your shoulders, hips, knees, and ankles.

4. Keep your ribs stacked over your pelvis.

5. Avoid rotating your chest toward the floor.

6. Continue breathing normally.

7. Lower yourself when you can no longer maintain the position.

The supporting elbow should remain underneath or close to underneath the shoulder.

The Most Important Side-Plank Cue

Keep your hips lifted and your body stacked.

Imagine that your body is positioned between two panes of glass.

Your chest and pelvis should face forward rather than rolling toward the floor or ceiling.

The goal is not simply to remain off the ground. The goal is to maintain alignment while your muscles work.

Side-Plank Variations for Beginners

Side Plank From the Knees

Bend both knees and support your body on your forearm and the side of your bottom knee.

Lift the hips while keeping a straight line from your head through your hips and knees.

This reduces the length of the lever and makes the exercise more manageable.

Side Plank With Staggered Feet

Place the top foot slightly in front of the bottom foot.

This provides a wider base of support and can make balancing easier.

Elevated Side Plank

Place your forearm on a bench, table, or other stable elevated surface.

The more upright your body becomes, the easier the exercise will generally feel.

Short-Duration Holds

Begin with five- to ten-second holds rather than attempting one long set.

Complete several high-quality repetitions with rest between them.

Intermediate Side-Plank Variations

Full Side Plank

Support your body on your forearm and stacked feet.

Keep your hips elevated and torso controlled.

Side Plank With Top-Leg Support

Place the top foot in front of the bottom foot for stability while keeping both legs straight.

Side Plank With Hip Dips

From a stable side plank, slowly lower the hips a small distance and lift them back into position.

Maintain control and avoid rotating the torso.

Side Plank With Arm Reach

Reach the top arm toward the ceiling or slowly move it overhead.

This changes the leverage and challenges shoulder and trunk control.

Side Plank With Rotation

Reach the top arm under the torso and then rotate back toward the ceiling.

This variation adds controlled trunk rotation but should only be used after you can maintain the basic position.

Advanced Side-Plank Variations

Side Plank With Top-Leg Lift

Lift the top leg while keeping the hips and torso stable.

This increases the challenge to the gluteus medius and other hip abductors.

Star Side Plank

Hold a full side plank while lifting both the top arm and top leg.

This requires significant shoulder, trunk, hip, and balance control.

Side Plank Row

Use a resistance band or cable to perform a row while holding the side-plank position.

Your core must resist rotation as the arm moves.

Side Plank With Knee Drive

Bring the top knee toward the chest without allowing the hips to drop or the torso to rotate.

Copenhagen Side Plank

Support the top leg on a bench while the bottom leg remains underneath.

This variation places greater demand on the inner-thigh and groin muscles and should be introduced gradually.

Weighted Side Plank

Place a light weight on the upper hip or use another form of resistance.

Additional load should only be added after the unweighted version can be performed with consistent technique.

Which Side-Plank Variation Is Best for Runners?

Runners may benefit from progressing through:

1. Side plank from the knees

2. Full side plank

3. Side plank with top-leg lift

4. Side plank with controlled knee drive

5. Side plank combined with single-leg exercises

The top-leg lift variation may be especially useful because it increases the demand on the lateral hip muscles.

However, runners should not rely on side planks alone. Standing and single-leg exercises are also needed to prepare the body for running.

Which Side-Plank Variation Is Best for Golfers?

Golfers may benefit from:

• Full side planks

• Side planks with rotation

• Side-plank rows

• Side planks with an arm reach

• Short, high-quality holds on both sides

Rotational variations should be controlled rather than fast.

Golfers need both the ability to resist rotation and the ability to create rotation when appropriate.

How Long Should You Hold a Side Plank?

A reasonable starting point is:

• 10 to 20 seconds per side

• Two or three rounds

• Two to four times per week

More experienced individuals may work toward holds of 30 to 45 seconds.

Longer is not always better.

Once a hold becomes easy, it may be more productive to progress to a more challenging variation rather than holding the same position for several minutes.

How Many Side Planks Should Runners Do?

Runners may begin with two or three sets of 10 to 30 seconds on each side.

The appropriate volume depends on:

• Training experience

• Running mileage

• Other strength work

• Injury history

• Exercise variation

• Current symptoms

Side planks can be performed after a run, during a strength workout, or as part of a separate mobility and stability session.

Avoid introducing a difficult new variation immediately before an important race or high-intensity workout.

How Many Side Planks Should Golfers Do?

Golfers may perform two or three sets per side as part of a strength program or warm-up.

Before playing, use shorter holds that activate the muscles without creating excessive fatigue.

During strength training, longer holds or harder variations may be appropriate.

Common Side-Plank Mistakes

Letting the Hips Drop

This is the most common mistake.

Once the hips drop, the body loses the straight position that makes the exercise effective.

Shorten the hold or use an easier variation.

Rotating Toward the Floor

The chest and pelvis should remain stacked.

Imagine keeping your belt buckle and chest facing forward.

Positioning the Elbow Too Far Away

The supporting elbow should remain close to underneath the shoulder.

An elbow positioned too far away may increase stress on the shoulder.

Shrugging the Shoulder

Press the forearm into the ground and create space between the shoulder and ear.

Do not allow the supporting shoulder to collapse.

Holding Your Breath

Continue breathing throughout the exercise.

If you must hold your breath to maintain the position, the variation may be too difficult.

Lifting the Hips Too High

The goal is a straight line—not pushing the hips as high as possible.

Overlifting may create unnecessary side-bending.

Holding Too Long

Once technique deteriorates, the set is over.

Several shorter, controlled holds are often more effective than one long, sloppy hold.

Why Do I Feel Side Planks in My Shoulder?

The supporting shoulder must stabilize the upper body during a side plank.

Some muscular effort is expected.

Shoulder discomfort may occur when:

• The elbow is not underneath the shoulder

• The shoulder collapses

• You are not pressing into the floor

• The variation is too difficult

• The shoulder lacks strength or stability

• There is a previous injury

Try the knee-supported or elevated version.

Stop if you experience sharp pain, pinching, numbness, tingling, or a feeling of instability.

Why Do I Feel Side Planks in My Hip?

The bottom hip muscles work to keep the pelvis elevated.

Muscular fatigue around the side of the hip can be expected.

Sharp joint pain, pinching, or symptoms traveling down the leg are not normal exercise sensations and should be evaluated.

Why Do I Feel Side Planks in My Lower Back?

Lower-back discomfort may occur when:

• The hips begin to drop

• The torso rotates

• The ribs and pelvis lose alignment

• The exercise is held too long

• The variation is too advanced

• Another area is not contributing effectively

Use a shorter hold or move to an easier variation.

The exercise should primarily feel like muscular effort through the side of the trunk, hips, and supporting shoulder.

Should You Perform Side Planks on Both Sides?

Yes.

Athletes should generally train both sides, even when their sport is asymmetrical.

Golfers, throwers, racquet-sport athletes, and soccer players may naturally develop side-to-side differences, but that does not mean one side should be ignored.

Start with the weaker or less coordinated side and match the duration on the stronger side.

Is It Normal for One Side to Be Weaker?

Some difference between sides is common.

A noticeable difference may be related to:

• Hand or leg dominance

• Previous injury

• Sport-specific demands

• Hip weakness

• Shoulder instability

• Reduced trunk endurance

• Pain avoidance

• Differences in coordination

Do not immediately add excessive volume to the weaker side.

Focus first on improving technique and gradually building capacity.

Are Side Planks Good for Lower-Back Pain?

Side planks may be useful for some people with lower-back discomfort because they train the trunk without repeatedly bending or twisting the spine.

However, lower-back pain has many potential contributors, including:

• Joint irritation

• Disc-related symptoms

• Nerve sensitivity

• Hip restrictions

• Muscle weakness

• Training overload

• Poor recovery

• Previous injury

The side plank is not appropriate for every person or every stage of recovery.

Stop if it causes sharp pain, radiating symptoms, numbness, tingling, or worsening discomfort.

Are Side Planks Better Than Regular Planks?

They train different qualities.

A front plank primarily challenges the body to resist extension through the spine.

A side plank places more emphasis on resisting lateral flexion and rotation.

Neither is universally better.

A balanced core program may include:

• Front planks

• Side planks

• Dead Bugs

• Bird Dogs

• Loaded carries

• Anti-rotation exercises

• Rotational strength exercises

Do Side Planks Make Your Waist Smaller?

Side planks strengthen the muscles around the trunk, but they do not selectively remove body fat from the waist.

Body composition is influenced by nutrition, total activity, resistance training, sleep, genetics, and overall energy balance.

The exercise should be valued for strength and function rather than spot reduction.

Can You Do Side Planks Every Day?

Some people can tolerate frequent short sets, particularly with easier variations.

However, recovery depends on the difficulty, volume, training schedule, and individual response.

Athletes completing harder side-plank variations may benefit from rest between sessions.

Stop or reduce the frequency if you develop persistent soreness, joint pain, or declining technique.

Should Side Planks Be Done Before or After Running?

Either can work depending on the goal.

Before Running

Use short holds as part of a warm-up to activate the trunk and hip muscles without creating fatigue.

After Running

Complete longer holds or more challenging variations as part of strength training.

On Strength Days

Combine side planks with squats, lunges, calf raises, deadlifts, and single-leg exercises.

Should Golfers Perform Side Planks Before a Round?

Short, low-fatigue holds can be included in a golf warm-up.

Avoid completing exhaustive sets immediately before playing.

A golf warm-up should also include:

• Hip rotation

• Thoracic rotation

• Dynamic movement

• Balance

• Gradual practice swings

• Progressive increases in swing speed

Frequently Asked Questions About Side Planks

What are side planks good for?

Side planks strengthen the lateral core, hips, shoulders, and spinal stabilizers while training the body to resist side-bending and rotation.

Do side planks strengthen the obliques?

Yes. The internal and external obliques help maintain the side-plank position and prevent the torso from rotating.

Are side planks good for runners?

Yes. They may help runners develop lateral hip and trunk control needed to stabilize the pelvis during single-leg stance.

Are side planks good for golfers?

Yes. Side planks can improve lateral trunk endurance and rotational control, which may support posture and force transfer during the golf swing.

Are side planks good for skiing?

They may help skiers improve lateral trunk and hip stability while the legs respond to changing terrain.

Do side planks strengthen the gluteus medius?

Yes. The gluteus medius and other lateral hip muscles contribute to maintaining pelvic position, especially during variations involving the legs.

How long should a beginner hold a side plank?

A beginner may start with five- to ten-second holds using the knee-supported or elevated variation.

How long is a good side-plank hold?

A controlled hold of 20 to 45 seconds is sufficient for many people. Technique matters more than achieving an arbitrary time.

Why is one side plank harder?

One side may have less shoulder stability, hip strength, trunk endurance, coordination, or confidence due to previous injury or sport-specific habits.

Can side planks help knee control?

Side planks may strengthen hip and trunk muscles that contribute to lower-extremity control. Knee function also depends on strength, mobility, technique, and load tolerance.

Are side planks safe during pregnancy?

Appropriate exercise during pregnancy depends on the stage of pregnancy, symptoms, prior training, and guidance from a healthcare provider. Modified or elevated variations may be more comfortable.

Can side planks hurt your shoulder?

They can irritate the shoulder when alignment is poor, the variation is too difficult, or a shoulder condition is present. An elevated or knee-supported version may reduce the demand.

What should I do if side planks cause back pain?

Stop, shorten the hold, or try an easier variation. Persistent or radiating pain should be evaluated.

How often should athletes perform side planks?

Two to four sessions per week may be appropriate for many athletes, depending on the variation and the rest of their training program.

A Strong Core Does More Than Create Movement

Athletes often train the core with crunches, twists, and sit-ups.

But during running, golf, skiing, cycling, and field sports, the core frequently has a different job:

It must prevent unwanted movement while force travels through the body.

The side plank develops this ability by asking the shoulder, trunk, pelvis, and hips to remain connected and controlled.

Start with the variation that allows you to maintain proper form. Progress only when you can keep your hips lifted, torso stacked, and breathing steady.

At Performance & Recovery Clinic in Basalt, Colorado, we evaluate how the spine, pelvis, hips, shoulders, and core work together during sports and daily movement.

For runners and athletes, an assessment may include:

• Single-leg stability

• Pelvic control

• Hip strength

• Trunk endurance

• Running or movement mechanics

• Shoulder stability

• Previous injuries

• Sport-specific demands

• Pain during training or competition

Care may include chiropractic adjustments, targeted manual therapy, individualized rehabilitation, sport-specific strength progressions, and Shockwave Therapy for appropriate tendon and soft-tissue conditions.

If recurring back, hip, knee, or shoulder discomfort is limiting your running, golf game, skiing, cycling, or training, schedule an evaluation and let’s build a plan to help you move, feel, and perform better.
