PowerBlock Personal Trainer Adjustable Dumbbell Set (2.5 to 50 Pounds) | Efficient, Cost Effective Strength Training
The PowerBlock Personal Trainer model adds 5 additional pounds to each dumbbell over the PowerBlock Classics (50 lbs vs. 45 lbs) but also increases versatility by lowering the increment value. The Personal Trainers are adjustable in 2.5 lb increments, compared to the 5 lb increments of the Classic set. In effect, the Personal Trainers replace 20 pair of dumbbells (2.5 - 50 lbs in 2.5 lb increments) while the Classics replace 9 pair (5 - 50 lbs in 5 lb increments).
All PowerBlock models are ingeniously engineered to save gym space and cost less than a full set of dumbbells covering the same weight range. Weight is adjusted using a selector pin that allows you to quickly increase or decrease weight between exercises. The weight handle fits inside the first weight, which fits inside the second, which fits inside the third, and so on. Padded handle grips increase comfort and wrist protection.
Weight can be adjusted in different variations, not just at 2.5 lb stages. Selecting in increments of 10 lbs is very quick, while smaller adjustments require removing the handle from the weight set, taking out a cylinder and then re-engaging the handle.
For some users the rectangular shape initially feels odd and clunky. One advantage to this design is that the size of the dumbbell decreases as you remove plates, improving the range of motion. By contrast, the Bowflex SelectTech adjustable dumbbells use a dial-up adjustment mechanism that maintains a constant dumbbell size regardless of weight. Another criticism of adjustable dumbbells in general is that you can't drop them on the floor after a set like traditional dumbbells.
The Powerblock Personal Trainer Dumbbells are designed to expand with your needs and can be used to build muscle mass, firm and tone or reduce body fat. They come with a limited 10-year warranty.
An optional PowerBlock Personal Dumbbell Set Stand is available.
