How to do the flat bench leg raises

  1. Lie on a flat bench with your hands under your hips supporting your back.
  2. Your legs should be unsupported by the bench from below your knees.
  3. With your feet together and your toes flexed upwards, raise your straight legs up a few cm off the bench; both of your legs should have no contact with the bench. This is your starting position.
  4. Keep your legs straight with a slight bend in the knees and raise your legs to just before 90 degrees with your hips.
  5. Pause at the top and lower your legs in slow controlled manner back to the starting position.
  6. Repeat.

Muscles worked

The prime movers are the rectus abdominis and the obliques, which flex the trunk forward and resist it being pulled into extension or twisted out of line.

How this movement works

Everything happens at one joint. That gives you direct control over where the tension sits; the trade-off is that the muscle gets no help, so the load that feels hard here is a fraction of what a multi-joint version of the pattern would take. Slow, complete repetitions beat heavy ones.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

No equipment at all. The resistance is your own bodyweight, so you progress by changing leverage, range or tempo rather than by adding plates — and you can do it anywhere.
