Before starting any exercise program please make sure you research the exercises to make sure you will do them properly for maximal health benefits as well as prevention of injury. You can hurt yourself even doing innocent sounding exercises like pushups or situps. I know people who have hurt their wrists badly by doing pushups so just make sure you know how to do them right. Additionally, dont try to do too much too fast. Build up to it at a healthy pace.
