High impact can do more harm than good. Like somebody else said, make sure you warm up and do what you can do safely. You're supposed to sweat. You're supposed to be sore (If I'm not sore then I don't think I really worked out). You're not supposed to give yourself tennis elbow or pull a tendon. If your muscles are sore, fight through the pain and you'll actually nullify the soreness. If your bones/joints are hurting then you've done something wrong. Take some time to recover.
