Rest
30s
Contraindications
Shoulder impingement — reduce range and avoid forcing full overhead position.Setup
Stand with the back, glutes, and head against a wall, feet a few inches out. Arms in a 'W' position, elbows and wrists against the wall.
Execution
- 1Slide the arms up the wall toward a 'Y' position, keeping wrists and elbows in contact
- 2Keep the low back flat against the wall throughout (don't let it arch)
- 3Slide back down to the starting 'W' with control
- 4Repeat for reps, maintaining wall contact as long as possible
Key cues
- Keep ribs down, don't let the low back arch off the wall
- Maintain contact with the wall at wrists and elbows as long as possible
- Move slow, this is a control drill, not a stretch to force
- Exhale as you slide the arms up
Common faults
- Arching the low back off the wall to fake more range
- Losing wall contact with the arms early in the range
- Shrugging the shoulders instead of rotating the scapula
- Moving too fast to actually train control
Tweaks
- Perform seated against a wall for a stricter lumbar lock
- Add a hold at the top 'Y' position for extra scapular endurance
- Progress by moving away from the wall while keeping the same pattern
