When to use it
- As part of a gym strength and conditioning session
- During training phases focused on body tension and positional control
- As supplementary conditioning for demanding reaching and lock-off positions
- After climbing, provided shoulder and trunk fatigue are manageable
The objective is to maintain body position through active trunk stabilization while the upper arm is supported by the strap, rather than relying primarily on elbow-flexor strength.
Preparation
Warm up the shoulders and trunk with controlled scapular movements and easy trunk activation. Check that the support strap is securely anchored and positioned comfortably beneath the upper arm.
Begin with one or two short, easy supported holds to establish the correct position before progressing to the working sets.
Starting position
- Secure a suitable support strap to a stable overhead anchor.
- Position the strap beneath the upper arm, between the shoulder and elbow, without placing pressure directly on either joint.
- Bend the supported elbow into a comfortable lock-off-like position.
- Position the body diagonally away from the support, as demonstrated.
- Keep the pelvis and shoulders aligned, avoiding unnecessary trunk rotation.
- Establish sufficient trunk tension to maintain a stable starting position.
Execution
- Allow the strap to support the upper arm while maintaining active control of the trunk.
- Hold the body in a stable diagonal position for the prescribed duration.
- Resist unwanted trunk rotation, lateral bending, and swinging.
- Maintain the upper-arm position without actively trying to pull yourself upward.
- Breathe normally while maintaining body tension.
- Return to a relaxed position under control, then repeat on the opposite side.
The objective is a stable isometric hold. Avoid turning the movement into an active one-arm pull or using momentum to maintain position.
Dosage
- 3–4 holds per side
- 10–15 seconds per hold
- RPE 5–7/10
- Alternate sides after each hold
- Approximately 60–120 seconds of recovery before repeating the same side
Adjust body position to achieve the prescribed intensity. Progress only while maintaining stable trunk and shoulder positioning.
Important
- The strap must securely support the upper arm without creating uncomfortable pressure near the shoulder or elbow. Use a suitable load-rated strap and a stable overhead anchor.
- Although the arm is supported, the shoulder and surrounding tissues may still experience substantial loading. Avoid painful positions and stop if you experience numbness, tingling, or increasing discomfort.
- Do not progressively reduce strap support as if performing an assisted one-arm pull-up. The strap is an essential part of this exercise, not merely a temporary assistance device.
Progression
Begin with a manageable body angle and focus on maintaining stable trunk and upper-arm positioning throughout each hold.
- Build up to 3–4 controlled holds of 15 seconds per side.
- Gradually increase difficulty by extending the body farther from the vertical support line.
- Maintain the same hold duration while increasing the demand on trunk stabilization.
- Progress only when you can maintain body alignment without twisting, swinging, or excessive shoulder tension.
Keep the strap supporting the upper arm throughout. The goal is greater trunk control under progressively more demanding body positions, not reducing arm support.
Expected effects
- Improved isometric trunk stability in unilateral support positions
- Better resistance to unwanted trunk rotation and lateral bending
- Improved coordination between the shoulder girdle, trunk, and pelvis
- Greater control of body tension in lock-off-like positions
- Improved ability to maintain stable body alignment under asymmetric loading
