Summary: Parents need to know that NFL Training Camp is a fitness program that uses isotonic and isometric exercises presented with a professional football theme. Training can be performed by two players, but the box only comes with one set of monitors and one rubber band (used for resistance exercises), so that if you want to exercise with another, you must buy another set of the equipment.
