Assisted Sit-Up (TRX / Suspension Trainer)
A TRX-assisted abdominal exercise where you perform a sit-up while holding the straps for balance and assistance.
Instructions
- Adjust the TRX straps to a moderate length
- Lie on your back with your knees bent and feet flat on the floor
- Grip the TRX handles with both hands positioned above your chest
- Keep a slight bend in your arms throughout the movement
- Engage your core and pull with your arms as you perform a sit-up
- Drive your chest toward your knees by flexing your abdominals
- The TRX straps provide assistance to make the movement more accessible
- Lower yourself back down with control to the starting position
Tips
- The TRX assistance allows those with weak abdominals to perform sit-ups
- Adjust strap length to increase or decrease the level of assistance
- Focus on the abdominal contraction rather than pulling with your arms
- This is excellent for progression toward unassisted sit-ups
- Keep your neck neutral; avoid pulling your head forward
- Gradually reduce reliance on the TRX as core strength improves
