Sometimes it takes some getting used to with the wrist flexibility, but it’s friendlier to the lower back.

Sorry for the late reply.

In principle, there shouldn’t be any difference in training a Man vs. Training a woman in terms of routines. In fact, Women often are BETTER suited to many of the the core exercises (like squats and cleans) than men are, because of their center of gravity being at the hips. Almost without fail, my best athletes are women.

If your knees and back are hurting, I’d first see a doctor to make sure that you don’t have a pre-existing injury that has been aggrivated by the lifting.

Other wise, here’s what I do to help prevent knee and Back injuries:

For the knee:

1: Stretch your quads (front of your thigh) and your calves. There is some research that suggests people with stiff quads and calves are more prone to knee injuries.
2: make sure on your squats, you go BELOW parallel (that is, your hip joint lower than your knee joint). If you stop above parallel, then all of the force of the weight will be directed straight to your knees. IF you go below, then that weight is shifted to your hips, where it belongs.
3. Always do specific Hamstring Work (back of thighs). Most people have stronger quads than hamstrings, and that is a precurser for knee pain.

For your Low back (I have a low back problem myself)
1. Stop doing back squats, and do Front Squats instead. They help you stay more upright, and put less strain on your low back
2. stretch your Butt and hamstrings. For the same reasons as for your knees. Keeping limber on the back side of your legs relieves a lot of pressure on the low back.
3. do back extentions in your warm up. make sure your low back is nice and warm before attempting to lift anything heavy.

I hope that helps. If that doesn’t work, then certainly there may be a bigger problem at play.
