PowerBlock U-33 Stage I Urethane Series Dumbbells
PowerBlock U-33 Stage I Urethane Series Dumbbells are part of the utherane series sets of dumbbells. PowerBlock is the most compact dumbbell available. At any weight, you will not find a shorter more compact dumbbell than PowerBlock. This means the PowerBlock U-33 Stage I Urethane Series Dumbbells has the weight more concentrated around your hand and makes the dumbbell easier to balance and control.
Having dumbells like the PowerBlock U-33 Stage I Urethane Series Dumbbells saves you space and money. The PowerBlock dumbbells will replace 16 pairs of dumbbells of 352 lbs of free weights with a weight range of 3-21 lbs.
Traditional weight training is an excellent way to build balance and strength, preserve bone density, and even add mass or reshape bodylines if you like. Traditional weight training includes all the machines and free weight implicated machines. Free weights, specifically dumbbells, used in controlled, slow movements, cannot be beat for effectiveness, safety, building strength, balance,coordination, and symmetry.
Free weight training, unlike machine training, forces you to control the weight in all planes of motion. This control is accomplished by the recruitment of synergistic and stabilizing muscles, so you are building a complete base of strength. Free weights are available as dumbbells, barbells and kettlebells.
We recommend dumbbells for reasons of safety (with barbells you need a spotter so you don’t get pinned) and for symmetry (you can’t cheat one side against the other like you can with barbells). PowerBlocks are the ultimate home dumbbell gym. Each set of PowerBlocks adjust quickly anywhere through the range of weight in about two seconds. Each set of PowerBlocks is the equivalent of many sets of traditional dumbbells. For example a single 90 lb Urethane Set is the equal of 34 pairs!
PowerBlocks, like the U-33 Stage I Set Urethane Series Dumbbells are ruggedly made, yet attractive and compact so they don’t take over the whole house or office. The cost per pound for PowerBlocks vs. the alternative of regular dumbbells and is very dramatic and the space savings is priceless!
