In my opinion, at the very beginning you should not be working out your muscles too hard. Try to train all your muscles, and don't exhaust an individual muscle too much. Otherwise you'll get muscle ache, and you have a bigger chance of injury. Besides, in the first trainings, your muscles start to use more of the muscle fibers - and I think that holds help for this - exercises like wall sit, holding pushup/crouch position as much as you can, and other similar. I think that in a week or two, you can start training more intense.
Anyway, I'm not that competent about this.
