Product Description

Amazon.com

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 personal trainer set is a hybrid system that employs the weight stack from PowerBlock's Personal Set and the handles of the Elite Set. As a result, users can achieve every 2.5-pound jump within the weight range of 2.5 to 50 pounds per dumbbell, in effect doing the job of 40 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. The personal trainer set is not expandable and is compatible with the Elite/Pro weight stand. It also carries a limited 10-year warranty.

4.0 out of 5 stars Some cautions and considerations August 31, 2007

By Patrick D. Goonan

I agree that these are the best adjustable dumbbells on the market. However, I would add a few caveats. For starters, it is important to have the PowerBlocks on a level surface and make sure you insert the pin straight across rather than at an angle. If you don't, it is possible that a plate could fall and hit you even with the elastic backup mechanism. It is also very important to put the pin assembly together right side up. If you don't, the magnets that hold this assembly in place don't engage.

On exercises like OVERHEAD triceps extensions, the points above are particularly important. While I think this product is great, it does limit range of motion in some exercises such as upright rows. The dumbbell is rather long and this could be a problem depending upon your frame. However, I wouldn't worry about the square design. I find using these dumbbells to be quite comfortable and the padded grips certainly help.

While this product is quite expensive, it's also the best out there that I know of and I shopped around carefully. It also seems to be the safest and is certainly more convenient, takes up less room and even costs less than a set of full dumbbells that can cover the same weight ranges.

If money is an issue for you, you may want to consider getting the model of dumbbells one tier down from these that adjust in 5 lb. increments and then purchasing adjustable wrist weights in 0.5 increments. This will give you about the same effect for less cost.

5.0 out of 5 stars Read if you Indecisive Over the Adjustable Dumbbell Choices April 15, 2010

By Dr. Zeus

After much research, I've purchased the Powerblocks Sport 9.0's that go up to 90 lbs. The 50lbs are expandable to the 90lbs, and then that set into the 130lbs. I am completely satisfied and excited by the set. My review is not to explain their function, but to save anyone the research time between Weider's, Bowflex, Ironmaster, Powerblocks, etc.

I purchased the Powerblocks over the Bowflex because I have not read one positive bodybuilding review concerning the Selecttech's durability. The plastic breaks easily, even when being gentle. Also, the bulkiness of the overall Selecttech makes moves like flies and presses difficult. Thus, the entire Selecttech system--although looks shnazzy--is impractical and a waste of money.

Thus, this left the only major contendor in terms of price, durability, and practicality: the IronMaster QuickLocks. Every other adjustable dumbbell is to be forgotten. These are the two major contendors.

The biggest difference between the Ironmasters and Powerblocks is one thing: speed vs. function. Both dumbbells are rock solid, but the Ironmasters are droppable. But how many people actually drop their dumbbells regularly? The Powerblocks are faster to switch between the weights, ESPECIALLY in terms of the Ironmasters slowness after 75lbs. However, every thread I've come across state both dumbbell brands are incredible in terms of durabilty, effectiveness, ugradeablability of up to around 130lbs, the outstanding customer service, and overall efficiency over multiple dumbells. The only downfall for the Ironmasters is the change time on weight over 75lbs. The only downfall for the Powerblocks is they make a little more noise.

The decision really is this in terms of adjustable dumbbells: do you want a more traditional looking dumbbell? Or something a little faster? Both are great designs, but I've found the Powerblocks to be the perfect choice. I hope I saved someone some time, because as long as you stick to either Ironmasters or Powerblocks for your adjustable dumbbell needs, you will be 100% satisfied for the years to come.

4.0 out of 5 stars Awesome February 19, 2008

By D. Miller

I bought the elite version (5 lbs empty handle up to 90 lbs) for about $600 from a local fitness store to avoid shipping and handling. Initially I thought the handle might restrict wrist movement but it hasn't been a problem. The trickiest part to using them is inserting the selector pins correctly and this is no biggie - just do it right so you don't dent the floor or your head. Selecting the weight in increments of 10 lbs is very quick. To make smaller adjustments requires removing the handle from the weight set, removing a cylinder or two and then reinserting the handle - not terribly time consuming but I find myself trying to avoid it during a workout. I use them for every exercise I would use a regular set of dumbbells except for pullovers. You can't drop these like regular dumbbells and I try not to bang them together. I have had them for about a year and use them at least twice a week. They look brand new. I would give them five stars if I wasn't taking into account the price.

12/9/10: No complaints. Solid piece of equipment. Cats like to chew on the elastic cords.
