Lightweight and easy to carry and store, resistance tubes are an ideal supplement or alternative to weight machines and free weights, helping build muscles by providing progressive resistance (an increasing amount of oppositional tension) as they are stretched. Great for use in aerobics, too. The medium-resistance tube provides 8.5-10.0 lbs. of resistance and features durable plastic grips. Great for use with P90X®. Length: 4 ft. Weight: 1 lb.
