Stay Focused, Train Hard!
If you are looking for a great way to define the muscles of your upper body, try kickboxing. Although it may sound like kickboxing is only good for working the lower body, it is actually a healthy, strength-building activity for your whole body. In addition to being a strength- building exercise, kickboxing works the heart muscle and creates an aerobic effect. Kickboxing has traditionally been thought of only as a martial arts activity, but is becoming an increasingly popular form of aerobics and strength training.
