Janda Sit-UpJanda Sit-Up

A sit-up variation that activates the glutes and hamstrings to inhibit the hip flexors, allowing the abdominals to work more effectively.

Instructions

  1. Position yourself on the floor in the basic sit-up position with your knees bent at approximately 90 degrees and your feet flat on the floor.
  2. Cross your arms over your chest or place them at your sides; this is the starting position.
  3. Strongly contract your glutes and hamstrings as you prepare to lift your torso.
  4. Inhale deeply, filling your lungs with air as you prepare for the upward movement.
  5. Begin your ascent by slowly raising your torso over a count of 3-6 seconds while exhaling.
  6. This glute and hamstring contraction activates a process called reciprocal inhibition, which causes the hip flexors to relax.
  7. Continue lifting until your torso is upright or your chest is toward your knees.
  8. Hold briefly at the top of the movement.
  9. As you inhale, slowly lower your body back to the starting position in a controlled manner.
  10. Repeat for the recommended number of repetitions.

Tips

  • The key to the Janda sit-up is the strong glute and hamstring contraction at the start of each rep.
  • This exercise allows your abdominals to work without excessive hip flexor involvement.
  • Move slowly and deliberately; the slower ascent enhances the effectiveness of the exercise.
  • For additional difficulty, hold a weight plate across your chest.
  • Maintain constant tension in your glutes and hamstrings throughout the entire movement.
  • This variation is excellent for those with hip flexor tightness or lower back issues.
  • Focus on quality of movement rather than quantity of repetitions.

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.
