Bent leg raise: how to do it
In short
A slow move on your back where you lower your feet toward the floor with your knees bent, then bring them back. Works: core and hips.

How to do it
- Lie on your back on a mat or folded towel on a non-slip floor. Get down to the floor slowly.
- Lift your feet so your knees are bent at 90 degrees, right over your hips. Arms rest by your sides.
- Let your lower back rest gently on the mat.
- Breathe out and slowly lower your feet toward the floor, keeping your knees bent.
- Stop before your lower back lifts, then breathe in and bring your feet back up.
- Do 8 slow reps.
As you go
- Lower only as far as your lower back stays gently down.
- Breathe out as you lower, breathe in as you return.
- Keep your neck and shoulders relaxed on the mat.

An easier and a harder version
Easier
Lower just one foot at a time, or make the range smaller.
Harder
Lower more slowly, about 4 seconds, or go a little closer to the floor.
Take care
- Back: if your lower back aches or lifts off the mat, make the range smaller.
- Hips: stop short of any pinch at the front of the hip.
- Neck: let your head rest on the mat. Never pull on your head.
