Secondary Muscles

A TRX core exercise where you raise your bent knees toward your chest while suspended, emphasizing hip flexor and abdominal strength.

Instructions

  1. Adjust the TRX straps to a shortened length
  2. Face away from the anchor point and grasp the handles
  3. Walk your feet back to create a plank position suspended by the TRX
  4. Your body should be in a straight line from head to heels
  5. Engage your core and bend your knees, driving them toward your chest
  6. Bring your knees as close to your chest as possible while maintaining body position
  7. Lower your legs back to the plank position with control
  8. Repeat for the desired number of repetitions

Tips

  • The bent knee position makes this more accessible than straight leg raises
  • The TRX instability requires significant core engagement for stability
  • Focus on driving your knees toward your chest rather than swinging
  • Control both the flexion and extension phases of the movement
  • Keep your hips aligned and avoid excessive hip dropping
  • This exercise builds core stability and strength effectively

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.
