Rated 5 out of 5 by from Excellent addition!! I was looking at these dumbells for a few weeks. I then had them purchased as a gift. I've been lifting weights for roughly 20 years now. Anyone who is a gym rat understands that with a nice adjustable bench you can do just about any movement with dumbells. They replace 9 sets of dumbells and feel just as good as standard hexadecimal head dumbells. I use them every day in my routine. My only knock would be this set is not expandable, the sport exp is. I thought I could purchase the add on kit to go from 50 to 70 then 70 to 90 pounds. This is an older set that doesn't allow expansion so I have to buy the heavier set now. Just for the simple reason 50 pounds isn't enough weight for me on most exercises. I do love the set up though just not enough weight.

Rated 4 out of 5 by from Beats the other options! I bought these for home use for a new workout program. In looking in the store, the units with the rotary selection for weight didn't work - neither of them. The PowerBlocks have been great thus far. However, I have found that the weight is not quite accurate. The base is supposed to weigh 10lbs. Both of my base units the weigh 9lbs. When you add the first plate, which should make the unit weigh 15 lbs., they actually only weigh 14.4, which means the first plate is 5.4lbs. If I weigh the entire set, both weigh 51.4lbs, which is higher than the 50lb rating. So be aware, that while they are consistent between the two dumbbells, they are not consistent with the true weigh. Also, the plastic piece holding the weight in place also looks like it could break down the road, but I assume that would be an easy fix. That said, it definitely beats having to buy multiple sets of various weights and then find somewhere to store all those dumbbells. For convenience and space, they can't be beat!

Rated 5 out of 5 by from Sport 50's are great Picked these for several reasons. When doing overhead tricep extensions, you can flip the unit over (upside down) and grab the two bars that were just on the bottom, one in each hand, and it feels very natural and controlled. With the Bowflex units I bought my son years ago, tricep extensions are more awkward. And although our Bowflex units haven't broken yet, when I went to the Dick's store, both of the Bowflex display units were broken so you couldn't adjust the weight, which didn't give me confidence. These Sport 50's were also attractive, without the gaudy colors that other Powerblock units have. And my son immediately noticed how compact they are, which helps during a lot of different exercises.

Rated 5 out of 5 by from The Best I thoroughly researched all of the adjustable dumbbells. Before buying, I was concerned that it might be awkward to use, but it isn't. Also got a good deal from Dicks.

Rated 5 out of 5 by from Great set of weights! I was having some serious issues with quick clipping between weights for a few minutes and realized that it was because they were sitting on carpet which made the pin not line up correctly. After sliding a piece of cardboard under my set of Powerblocks everything lines up perfectly, so sitting them on a hard surface is key to quick changes.Other than that, i have been using them non stop on a daily basis and really enjoy their quality and ease of use.Highly Recommended

Rated 5 out of 5 by from Great dumbbell set! Worth EVERY penny! Don't buy Bowflex or any orther brand. Look nowhere else for an adjustable dumbbell set. The Power Block 50's are perfect for any type of space availability. Their design is simplistic and sound which means no breakdowns like the other competition that uses dials. I also appreciate the design because I have large hands and they fit into the Power Blocks very well compared to the older version. I went to Dicks to look over & compare them to the competition. The Bowflex weights were jammed on the dial and couldn't change and the other brand looked like they were made better but they were jammed as well. After making my decision, I had them ordered and delivered with free shipping. My 11 year old son likes using them as well. With a range of 10-50 pounds, just about anyone can use them. VERY STURDY BUILD! I highly recommend!!!

Rated 5 out of 5 by from Very Happy After using the PowerBlock Sport 50 for two weeks now, I can honestly say that I am very happy with my purchase.This PowerBlock differentiates itself from its more notable PowerBlock peers by increased weight by 5 lb. increments using the pin. The larger PowerBlocks have two cylinders within the block (each able to contain a 2.5 lb. weighted cylinder). This throws off the balance slightly, and is a slight inconvenience compared to just using the all-in-one pin. I know – I said “slight inconveneice.” But I wanted the closest thing I could get to the ease of just picking up the next set of dumbbells… then put them down and pick up the next set. This was also one of the safest and most solid set of adjustable dumbbells I could find.Reasons why I chose this over the Bowflex 552s:Flat & smooth sides on the ends – when I am sitting down on my bench, I prefer to rest dumbbells on my legs before and after a set, and other adjustable dumbbells (Bowflex) do not accommodate this. Try doing bicep curls with the Bowflex before you purchase them – they are so incredible wide I found myself catching the sides of my legs every rep. These PowerBlocks are much more compact – so no issues here. Both Bowflex demo models at Dicks were broken when I went in to the store. After doing some reading, it turns out they have a reputation for breaking and occasionally dropping a weighted disk. If you’re going to move around a heavy weight over your face, I would want to be as confident as possible that it’s not going to break or come down on me.Pros:Compact, easy to use, very fast to change weight settings, well-balanced, efficient in terms of cost and space. Cons:You have to get over the psychological barrier of sticking your hands inside of the metal “cage.” When doing an overhead tricep extension, it’s a bit uncomfortable – both of my hands manage to fit inside one block, but in this position, part of the block tends to rest on my wrist, making things a little uncomfortable.

Rated 4 out of 5 by from Great product, but... I really like the idea of this product, but be aware. According to PowerBlock customer support, this set does not support an expansion set. So if you want to go any heavier than 50 per hand, you might want to go with their other sets. This works great for me now, but I worry I will out pace it eventually, and it won't be heavy enough.
