How to Perform the Janda Sit-Up
- 1
Lie on your back with knees bent and feet flat on the floor.
- 2
Have a partner hold your calves, or loop a resistance band behind your calves anchored in front of you.
- 3
Actively pull your heels back against the resistance to engage your hamstrings and glutes (this inhibits the hip flexors).
- 4
Cross your arms over your chest.
- 5
Exhale and slowly curl your torso off the floor using only your abs.
- 6
Inhale and slowly lower back down.
Common Mistakes to Avoid
- !Rushing reps instead of controlling the lowering (eccentric) phase — aim for 2–3 seconds down.
- !Letting form break down as reps add up. Stop the set when technique slips, not when you physically can't do another rep.
- !Using momentum to swing through reps. Pause briefly in the contracted position to keep tension on the muscle.
Tips for Better Form
- ✓Breathe out during the effort (concentric) and breathe in on the return (eccentric).
- ✓Use a mirror or film yourself on your first session — your perceived form and actual form often differ.
- ✓Keep ribs down and lats engaged — this keeps tension on the core, not the hip flexors.
- ✓Start each set with 1–2 warm-up reps at a lighter load to groove the movement.
