U-pose– PICTURE – Women's Health & Fitness

You don’t have to have perfectly straight legs for this one.

But you do need to ensure you are not leaning back onto the lower back or bringing your knees into your chest. Sit and lift up your feet to the sky.

Bring your upper body into a V position and hold there as long as you can.

Beginner version

Gently clasp behind your hamstrings to support.

Bending your knees to start with is okay to get the connection working in your lower back.
