Despite what infomercials and clever marketing may lead you to believe, getting in shape isn't as simple as taking a "miracle" pill, eating only protein or using some knock-off gizmo three times a week. You do need discipline, and you'll need to make wise food choices and some sacrifices to attain the results you desire. That aside, the key to getting in shape and being healthy is pretty basic. Although there's no "one way" that's going to be effective for all persons, the best approach to optimal health and fitness combines a sensible diet strategy with a sound exercise program consisting of both aerobic and anaerobic (weight training) activity.
