Crunch and sit-up alternatives

Crunches and sit-ups can strain the neck and lower back, and they are not the only way to train your abs. These alternatives work the same muscles lying down, hanging or on a machine.

If something hurts

Start with the easier number and build up over a couple of weeks. Stop if something hurts, and ask a doctor or physiotherapist about pain that stays - this is general guidance, not medical advice.
