Diver
Reach the arms forward and round the upper back like a diver entering the water.
Overview
Diver is a beginner seated flexion stretch on Flexor that reaches the arms forward and rounds the upper back like a diver entering the water.
What Diver targets
You'll feel length through the thoracic spine, rear shoulders, and upper back as the head tucks between the arms.
Why add Diver to your routine
Opens the upper back and posterior shoulder line through flexion.
- Encourages controlled spinal rounding away from desk extension.
- A compact seated stretch when floor space is limited.
Who it's for
Desk workers and swimmers who need thoracic flexion after long extension postures.
When to do it
Use between desk sessions, in cool-downs, or before thoracic extension work.
Diver is a seated spinal-flexion stretch that stacks the hands, tucks the head between the arms, and rounds through the upper back. It creates length through the thoracic spine and rear shoulders.
Setup cue
Sit tall with arms resting by your sides and feet grounded. Reach both arms forward, stacking one hand on top of the other — keep it smooth.
Practice notes
In Flexor, Diver is typically prescribed as about 45 sec per round, 1 rep, and 1 set. Adjust the dosage to what feels sustainable, breathe steadily, and ease off if anything feels sharp or unsafe.
