A TRX-assisted abdominal exercise where you perform a sit-up while holding the straps for balance and assistance.

Instructions

  1. Adjust the TRX straps to a moderate length
  2. Lie on your back with your knees bent and feet flat on the floor
  3. Grip the TRX handles with both hands positioned above your chest
  4. Keep a slight bend in your arms throughout the movement
  5. Engage your core and pull with your arms as you perform a sit-up
  6. Drive your chest toward your knees by flexing your abdominals
  7. The TRX straps provide assistance to make the movement more accessible
  8. 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

Recommended starting values

Sensible novice starting points for each goal, for a lifter aged 25–40. Scale down for smaller frames or older lifters. Treat the first set of any session as a discovery set.
