Soreness after workouts is generally caused by microscopic tears in the muscle fibers. It's called DOMS (delayed onset muscle soreness) and realistically, there's not much you can do to prevent it, other than than maybe dialing back the workouts a lot if this is a consistent problem. Your body will eventually adapt, and it won't hurt so much, but if it continues, you may be overtraining.
