Resisted Sit-Up (TRX / Suspension Trainer)
An abdominal exercise where the body is suspended in TRX straps and performs a sit-up motion with additional resistance from the handle position.
Instructions
- Sit facing the anchor point with feet under the anchor and knees bent at approximately 90 degrees
- Hold the TRX handles at chest height with arms bent
- Lean back slightly, creating tension in the straps
- Use your abdominals to sit up, bringing your chest toward your thighs
- At the top position, press the handles forward with your chest
- Return to the starting position with control
- Complete the prescribed reps
Tips
- The TRX adds an element of instability and increased challenge
- Focus on core strength rather than relying on hip flexors
- Keep tension in the straps throughout the movement
- The chest press at the top engages your chest and anterior core
- Exhale as you sit up and press, inhale as you return
- This movement builds core strength and chest activation
