Can you reach both arms overhead without arching your lower back, flaring your ribs, or shrugging your shoulders toward your ears?
Many people appear to have adequate overhead mobility—but only because their lower back compensates for a stiff upper back or restricted shoulders.
That compensation may become more noticeable after:
Sitting at a desk
Driving for long periods
Cycling
Golfing
Swimming
Climbing
Strength training
Working with the arms in front of the body
Repeated overhead activity
The Dolphin Stretch is a wall-supported mobility exercise that can help open the shoulders, upper back, lats, and chest while allowing you to control how much pressure you apply.
The video below demonstrates a more advanced PVC variation. The wall-supported Dolphin Stretch offers a useful starting point for many people.
Watch Dr. Joe Demonstrate the Advanced PVC Thoracic Opener
The goal is not to push your chest as close to the floor as possible.
Instead, focus on creating a gentle stretch through the shoulders and upper back while keeping your lower back controlled.
What Is the Dolphin Stretch?
The Dolphin Stretch is a shoulder and thoracic-mobility exercise performed with the hands, forearms, or elbows supported against a wall, bench, table, or other raised surface.
From there, you hinge your hips backward while allowing the chest to move between the arms.
The movement may help improve:
Shoulder flexion
Thoracic extension
Lat mobility
Chest mobility
Overhead positioning
Rib-cage movement
Awareness of spinal compensation
It resembles the upper-body position of a yoga Dolphin Pose but uses a supported surface to make the movement easier to control.
What Is the PVC Thoracic Opener?
The PVC Thoracic Opener is a more advanced version of the same general mobility concept.
You hold a PVC pipe or dowel while placing the elbows or forearms on a raised surface.
As the hips move backward and the chest lowers, the PVC pipe helps maintain arm position and may increase the stretch through the:
Shoulders
Triceps
Latissimus dorsi
Thoracic spine
Chest
Rib cage
Because the PVC version creates greater leverage, it can feel significantly more intense than the wall-supported Dolphin Stretch.
Beginners should generally start with the wall.
How to Perform the Wall Dolphin Stretch
Stand facing a wall.
Place your hands or forearms against the wall at approximately shoulder height.
Walk your feet backward slightly.
From this position:
Keep your hands or forearms supported.
Soften your knees.
Push your hips backward.
Allow your chest to move between your arms.
Keep your ribs gently controlled.
Avoid aggressively arching your lower back.
Pause when you feel a comfortable stretch.
Return slowly and repeat.
You may move your arms higher or lower on the wall to find the position that feels best.
How to Perform the Bench or Table Version
Place your elbows or forearms on a stable bench, table, or treatment table.
Step backward and hinge at the hips.
Allow your chest to lower while keeping the elbows supported.
For a stronger triceps and lat stretch, bend the elbows and bring the hands toward the upper back.
Maintain gentle abdominal tension so the movement does not come entirely from the lower back.
How to Perform the PVC Variation
Place your elbows on a padded bench or raised surface while holding a PVC pipe or dowel.
Your hands may be positioned wider than your elbows depending on the variation.
From there:
Keep the elbows supported.
Hold the PVC pipe securely.
Move the hips backward.
Allow the chest to lower gradually.
Keep the ribs from excessively flaring.
Maintain a comfortable head and neck position.
Pause briefly.
Return without bouncing.
The PVC should guide the position—not force the shoulder into a painful range.
The Most Important Form Cue
Move your chest through your arms without arching your lower back.
A person with limited shoulder or upper-back mobility may appear to move farther by allowing the ribs to flare and the lumbar spine to extend.
That creates the appearance of more overhead motion without necessarily improving mobility where it is needed.
Think about gently drawing the lower ribs toward the pelvis before moving deeper.
Should You Feel the Stretch in Your Shoulders or Upper Back?
You may feel the stretch through several areas, including:
The outside of the shoulders
The back of the upper arms
The lats
The chest
The side of the rib cage
The middle or upper back
The stretch should feel broad and controlled.
You should not feel sharp pinching in the front or top of the shoulder.
Why Does the Stretch Affect the Thoracic Spine?
The thoracic spine is the middle and upper portion of the back.
Reaching overhead requires coordination between:
The shoulder joint
Shoulder blade
Thoracic spine
Rib cage
Chest and lat muscles
If the upper back remains rounded or stiff, the arms may have difficulty reaching fully overhead without compensation.
The Dolphin Stretch encourages the chest to move between the arms, creating an extension demand through the thoracic spine.
Can the Dolphin Stretch Improve Posture?
It may help improve awareness and mobility through areas commonly held in a flexed position during desk work and driving.
The exercise can be useful for people who feel:
Rounded through the upper back
Tight across the chest
Restricted reaching overhead
Stiff after sitting
Fatigued between the shoulder blades
However, posture cannot be permanently corrected by one stretch.
Long-term improvement also requires:
Upper-back strength
Shoulder-blade control
Regular movement breaks
Workstation changes
Strength through the available range
Variation in sitting and standing positions
Is the Dolphin Stretch Good for Desk Workers?
Yes.
Desk work commonly keeps the arms in front of the body while the upper back remains relatively still.
The Dolphin Stretch moves the shoulders overhead and encourages extension through the upper back.
Desk workers may use it:
During a movement break
After work
Before strength training
After prolonged computer use
Between meetings
A brief set of controlled repetitions may be more useful than waiting until the upper back becomes extremely stiff.
Is It Helpful After a Long Car Commute?
Yes.
Driving keeps the shoulders forward and the hands in front of the body for prolonged periods.
After safely exiting the vehicle, the wall Dolphin Stretch may help restore movement through the:
Shoulders
Upper back
Chest
Lats
Rib cage
It should be combined with walking and changing positions rather than used as the only solution.
Is the Dolphin Stretch Good for Golfers?
Golfers need sufficient shoulder and upper-back mobility to create a comfortable backswing and maintain posture.
Restricted overhead or thoracic motion may contribute to:
A shortened shoulder turn
Excessive lower-back extension
Difficulty maintaining posture
Stiffness between rounds
Shoulder tension
Compensatory arm lifting
The Dolphin Stretch may help improve the mobility foundation needed for the swing.
It should be paired with:
Thoracic rotation
Hip rotation
Core stability
Shoulder strength
Golf-specific movement practice
Is It Good for Swimmers?
Swimmers repeatedly move the arms overhead and require coordinated shoulder-blade and thoracic motion.
The stretch may help address:
Lat tightness
Overhead restriction
Thoracic stiffness
Shoulder flexion limitations
Post-training tightness
Swimmers also need rotator-cuff strength, scapular endurance, technique, and appropriate training-volume management.
Is It Good for Climbers?
Climbers spend significant time with the arms overhead and often develop strong pulling muscles.
The Dolphin Stretch may help improve:
Overhead shoulder mobility
Lat length
Thoracic extension
Triceps mobility
Reach positions
Climbers should avoid aggressively stretching an unstable or painful shoulder.
Mobility should be balanced with shoulder strength and control.
Is It Good for Lifters and CrossFit Athletes?
Yes.
Overhead pressing, snatches, overhead squats, front-rack positions, and gymnastics movements require significant shoulder and thoracic mobility.
The Dolphin Stretch may help athletes prepare for:
Overhead presses
Pull-ups
Snatches
Overhead squats
Handstands
Front-rack mobility
Kettlebell work
It should not be used to force the shoulders into a range that cannot yet be actively controlled.
Is It Good for Cyclists and Mountain Bikers?
Cyclists spend long periods with the upper back flexed and the arms reaching toward the handlebars.
The Dolphin Stretch may help counter that position by moving the shoulders overhead and encouraging thoracic extension.
Cyclists may also benefit from:
Neck endurance
Upper-back strength
Shoulder stability
Hip mobility
Bike-fit adjustments
Changing hand positions
Is It Good for Skiers?
Skiers frequently maintain a flexed posture while holding the arms forward.
The stretch may help restore upper-back and shoulder motion after skiing, particularly for people who feel stiff after using poles or remaining in an athletic stance.
How Long Should You Hold the Stretch?
A useful starting point is:
15 to 30 seconds
Two or three repetitions
One or two rounds
You can also perform it dynamically:
Move gently into the position
Pause for two or three seconds
Return slightly
Repeat five to ten times
Dynamic repetitions may be better before activity.
Longer holds may be more appropriate after training or at the end of the workday.
How Often Can You Perform the Dolphin Stretch?
Many people can perform the wall-supported version daily.
Frequency depends on:
Stretch intensity
Current shoulder symptoms
Training volume
Mobility needs
Recovery
The more advanced PVC variation may require less frequent use if it creates significant soreness.
Should You Use the Wall or a Bench?
The wall is generally the easiest version because you can remain more upright.
A bench or table creates a more horizontal position and usually increases the stretch.
A simple progression is:
Hands on the wall
Forearms on the wall
Forearms on a high table
Elbows on a bench
Bent-elbow bench variation
PVC thoracic opener
Progress only when the previous version feels controlled.
Should You Perform Repetitions or Holds?
Use repetitions when the goal is:
Warming up
Reducing stiffness
Improving movement awareness
Preparing for overhead exercise
Use longer pauses when the goal is:
Improving stretch tolerance
Addressing persistent tightness
Restoring motion after activity
You can also combine them by performing five repetitions followed by one 20-second hold.
Why Do I Feel the Stretch in My Lats?
The latissimus dorsi connects the upper arm to the trunk and pelvis.
It contributes to movements such as pulling the arm downward and backward.
When the arms are overhead and the hips move backward, the lats may be placed in a lengthened position.
A gentle lat stretch is expected.
Why Do I Feel It in My Triceps?
The long head of the triceps crosses the shoulder joint.
Bending the elbow while reaching overhead can increase tension through this muscle.
This is especially noticeable during the PVC or hands-behind-the-head variation.
Why Do I Feel It in My Lower Back?
You may be compensating by arching the lumbar spine rather than moving through the shoulders and upper back.
Try:
Moving less deeply
Gently tightening your abdomen
Keeping the ribs controlled
Bending the knees slightly
Moving your hands lower on the wall
Using a more upright version
The stretch should not create a concentrated pinch in the lower back.
Why Do I Feel Pinching in My Shoulder?
Shoulder pinching may occur when:
The movement is too deep
The hands are too narrow or too wide
The shoulder joint is irritated
The shoulder blade is not moving well
The chest collapses too aggressively
The PVC creates too much leverage
Reduce the range or return to the wall variation.
Do not repeatedly force through pinching.
Should the Elbows Stay Straight or Bent?
Both positions can be useful.
Straight Elbows
This usually creates more of a shoulder-flexion and lat stretch.
Bent Elbows
This often increases the stretch through the triceps and may create a deeper thoracic-opening sensation.
The bent-elbow version is generally more intense.
Common Dolphin-Stretch Mistakes
Arching the Lower Back
Keep the lower ribs gently controlled and reduce the depth.
Forcing the Chest Down
Move gradually. More depth is not always better.
Shrugging the Shoulders
Allow the shoulders to move naturally, but avoid creating excessive neck tension.
Holding the Breath
Continue breathing slowly into the rib cage.
Using an Unstable Surface
Use a wall, bench, or table that will not move.
Forcing a Painful Shoulder
A stretch should create tension, not sharp or pinching pain.
Moving the Hands Too Close Together
A very narrow hand position may be uncomfortable for people with limited mobility.
Start slightly wider.
Can This Stretch Fix Rounded Shoulders?
No single exercise can permanently correct rounded shoulders or thoracic kyphosis.
The Dolphin Stretch may improve mobility and awareness, but lasting changes usually require a combination of:
Thoracic mobility
Chest and lat mobility
Upper-back strength
Rotator-cuff training
Shoulder-blade control
General strength training
More movement throughout the day
Structural spinal curves also vary naturally between individuals.
Is This Stretch Safe With Shoulder Pain?
It depends on the cause of the pain.
The stretch may be appropriate for some people with mild stiffness, but it may aggravate:
Acute rotator-cuff pain
Shoulder instability
Recent dislocation
Adhesive capsulitis
Significant arthritis
Recent surgery
Certain labral injuries
Stop if you experience sharp pain, catching, weakness, numbness, tingling, or instability.
Is It Safe With Neck Pain?
The neck should remain relaxed and relatively neutral.
Some people find the position comfortable, while others experience increased neck tension.
Try resting the forehead on a towel or reducing the depth.
Stop if symptoms travel into the arm or hand.
When Should You Avoid the Advanced PVC Version?
Use the wall-supported version or seek guidance if you have:
Acute shoulder pain
Recent shoulder surgery
A history of dislocation
Significant shoulder instability
Painful overhead motion
Elbow pain
Numbness or tingling
A recent upper-body injury
Difficulty controlling the ribs and lower back
The advanced variation should be earned gradually.
Frequently Asked Questions About the Dolphin Stretch
What is the Dolphin Stretch good for?
It is used to improve shoulder flexion, upper-back extension, lat mobility, and overhead positioning.
Is the Dolphin Stretch good for posture?
It may help improve mobility and awareness after prolonged sitting, but posture also requires strength and regular position changes.
What is a PVC thoracic opener?
It is an advanced mobility drill that uses a PVC pipe and raised surface to increase the shoulder, triceps, lat, and thoracic-spine stretch.
Is the wall version easier?
Yes. The wall-supported Dolphin Stretch allows you to control the depth and is more appropriate for many beginners.
Where should I feel the stretch?
You may feel it through the shoulders, lats, triceps, chest, rib cage, or upper back.
Should I feel it in my lower back?
Not primarily. Lower-back pressure often means you are compensating by arching.
Can it help shoulder mobility?
It may help improve overhead shoulder motion when stiffness through the shoulders, lats, or thoracic spine is contributing.
Can it help thoracic kyphosis?
It may improve mobility and awareness, but it cannot completely reverse a fixed structural spinal curve.
Is it good for swimmers?
Yes. It may help address overhead mobility and lat tightness when combined with shoulder strength and proper training.
Is it good for golfers?
Yes. Upper-back and shoulder mobility contribute to a comfortable backswing and rotational movement.
Is it good before overhead lifting?
Dynamic repetitions may be useful as part of a warm-up before presses, pull-ups, snatches, or overhead squats.
Can desk workers do it every day?
Many people can use the gentle wall variation daily, provided it does not cause pain.
How long should I hold it?
Start with 15 to 30 seconds or five to ten controlled repetitions.
Should I bend my elbows?
Bending the elbows increases the triceps component and generally makes the stretch more intense.
Why does the PVC version feel much harder?
The dowel creates additional leverage and maintains the arms in a more demanding position.
What should I do if my shoulder pinches?
Reduce the depth, widen the hands, or return to the wall-supported version. Persistent pinching should be evaluated.
Do Not Borrow Shoulder Motion From Your Lower Back
Reaching overhead should involve coordinated movement through the shoulders, shoulder blades, rib cage, and upper back.
When those areas are restricted, the body often creates the missing motion by arching the lower back.
The Dolphin Stretch is a useful way to explore that relationship.
Start against the wall. Keep the ribs controlled. Move gradually.
Progress to the bench or PVC variation only when you can maintain a comfortable shoulder and lower-back position.
