PowerBlock Personal Adjustable 5 to 45-Pounds per Dumbbell Set

The only dumbbell system that can expand to meet your strength needs, PowerBlock dumbbells are the most versatile and effective exercise tool ever developed for strength training. PowerBlocks work intuitively. Rather than requiring you to buy a room full of dumbbells, PowerBlocks act just like a weight stack at the gym, with a weight handle that fits inside the first weight, which fits inside the second, which fits inside the third, etc. When you want to change weights, you simply move the weight selector pin into the appropriate slot and you're set. As you lift the core, all the weights above the selector pin are lifted at the same time, turning your 3-pound dumbbell into a 6-pound dumbbell, or your 6-pound dumbbell into a 12-pound dumbbell. Not only is the system remarkably easy to use, but it's also cost- and space-efficient, as a single pair of dumbbells can do the work of dozens.
This pair of 45x5 dumbbells, for instance, adjusts from 5 to 45 pounds in 5-pound increments (5, 10, 15, 20, 25, 30, 35, 40, and 45 pounds), in effect doing the job of 18 individual weights. Even better, the weights are more compact and balanced than traditional dumbbells, with a padded handle that protects people with weak wrists. Best of all, the free weights are terrific whether you're trying to build muscle mass, firm and tone your physique, or get rid of unwanted body fat.

Customer feedback:

1. I bought these dumbbells from a local dealer instead of Amazon because of a sale. I had been looking at the Bowflex select-type of dumbbells as well as these. After trying them out at the store, I was sold. They are easy to manipulate and sturdy in construction. One would think that a square dumbbell would get in the way of doing exercises--this is NOT the case. The handle is in the middle of the box and the side tubes are padded for comfort.
I just finished an hour long dumbbell workout a few minutes ago and it was everything I expected: bench press, military press, bent over rows, seated curls, triceps extensions, dumbbell deadlifts, upright rows, dumbbell squats, etc... All of these exercises were performed using this product. No problems encountered at all.

2. I like that there is a back up system of an elastic cord and magnets holding the pin mechanism in place. I have found there is only a real danger on certain exercises and only if you don't follow the instructions. Even then the odds are small anything will happen, but it's something I want to warn people about because I have had some near misses.
I find the smaller version of these are better than the larger version. The large version can be cumbersome and a bit long for some exercises. However, I agree with the other reviews you can comfortably do a variety of exercises and the trade-off in terms of a slightly smaller range of motion on some particular exercises isn't a big deal. For example, for upright rows I tend to prefer a short curling bar... ditto for overhead triceps extentions. However, using one dumbbell with two hands is possible and quite comfortable.
