The best short-term thing to minimize muscle soreness is a proper cooldown. Learn some gentle stretches or yoga type stuff where you aren't pushing your body further, just to keep the muscles limber after you get into the house instead of crashing out on the sofa and being suddenly sedentary. A hot bath or shower can also be a huge help.
