....so on the recommendation of someone on this board, and wanting to get into better shape, I picked a copy of New Rules of Lifting and my fiancee and I are currently working through the beginner's routine. Deadlifts, squats, awesomeness all around.
Now, I admit that I'm rather weak and can't bench a thing, and she's never done any weight training at all before, so for the pushups in the beginner routine (it's in a superset with crunches), I'm doing them on my knees. But my fiancee can't even manage that, her core and lower back collapse on the way down (sort of like an ugly reverse upwards dog in yoga) before she bends her arms.
It looked so bad that I had her do one of the chest press machines instead, but I know that's not the same exercise.
Anyone have any tips for working up to good pushups if you can't even manage from the knees yet?
