Here is how to do a weighted leg raise:
1. Lie on your back, legs straight and together. Grad a 10 lb or 20 lb weight and hold it above your face
2. Keep your legs straight and lift them all the way up to the ceiling until your butt comes off the floor.
3. Slowly lower your legs back down till they’re just above the floor. Hold for a moment.
4. Raise your legs back up. Repeat.
