Answers: - lie on your stomach, simultaneously heave left paw and right leg, then switch, do it faster and pretend to be swimming
- feign on stomach, put hands beside your chest but don't use them for support, hoist legs
- go on adjectives fours and do a cat stretch
Lay down on your back and heave your legs as far onto you as you can
then hold your heels beside your hands
These should back you.

If you've got a problem near your lower back, I'd seriously suggest getting professional direction. You could do more harm than fitting otherwise.
