Alternative Workout Idea: Tai Chi
The seemingly serene, soothing practice of tai chi can actually give you a competitive edge on court, field or other arena of high-intensity contest.
Tai chi improves flexibility, balance and coordination -- all key in athletics. It also enhances your ability to focus and concentrate.
In addition, tai chi can help protect you against knee strain or injury, because the continuous, fluid movements strengthen the small stabilizing muscles that surround and support the knees.
