There are a lot of health benefits which we get from exercising. However some of us have no idea that we get injured from exercising. The best exercise is an activity that you enjoy enough to really pursue enthusiastically. Experiment with different forms of activity (cross training). Alternating new activities with old favorites will keep your enthusiasm high. Cross training also helps avoid injury due to repeatedly doing the same activity.
Furthermore, flexibility is a critical element of an exercise program but it is often overlooked. Stretching is important for a number of reasons; increases physical performance, decreases risk of injury, increases blood supply and nutrients to the joints, increases neuromuscular coordination, reduces soreness, improves balance, decreases risk of low back pain, and reduces stress in muscles.
