This is a nice, compact weight set. It could work well as a starter set for kids, as a lighter set for elderly, or just a simple set for those who want to stay toned and mix some basic weight-bearing exercises into their workouts. It’s nice that the weights are rubber coated and look less “industrial” – you could leave this set out in your carpeted bedroom. (See photos.)Some possible issues to consider: First, the plates are of odd weights: 4.4 pounds, 3.3 pounds, and 2.8 pounds. That doesn’t make it terribly easy to calculate the total weight with any combination of the plates, or to easily track your progress (i.e., it’s much easier to remember that you lifted 5 more pounds in weights today then 4.4). Second, the dumbbell and barbell bars have no indication of their weight, so you really don’t know the total weight you’re lifting. If interested, the dumbbell bars alone (with collars) each weigh 0.8 pounds. The barbell bar (with both dumbbell bars screwed in and with collars) weigh 2.5 pounds. I’d recommend creating a one-time chart of all possible dumbbell and barbell weight combinations (a starter example is at the end of this review), so you can instead just refer to your chart to know what combination of plates you need.Third, the length of the screw-end portions of the bars is long. It takes a noticeable amount of time to screw and unscrew the dumbbell bars into/from the center for the barbell bar. Even when you’re using only one set of plates on any bar, it takes an equally noticeable amount of time to screw and unscrew the collars. That is, these are not “quick-change” weights where you can easily switch from using the barbell to the dumbbell bars, or even quickly change weights. This set would have been much more functional if the dumbbell bars locked into the barbell bar with a quick-release pin and if the collars were spring collars instead of screw collars. But if you vary your exercises by day (e.g., you do dumbbell exercises on Monday and barbell exercises on Wednesday), then you might not mind having to do all the screwing and unscrewing of the parts to switch between the two.Here’s a partial example of the chart I recommend creating if you do use this weight set (remember to add 0.8 pounds for each dumbbell, and 2.5 pounds for the barbell):DUMBBELL with… Two 2.8 plates = 6.4 pounds Two 3.3 Plates = 7.4 pounds… Two 3.3 and Two 4.4 plates = 16.2 pounds… Two 2.8 and Four 4.4 plates = 24 pounds… etcBARBELL with… Two 2.8 plates = 8.1 pounds… Two 2.8, 3.3, and 4.4 plates = 23.5 pounds… Four 2.8, 3.3, and 4.4 plates = 44.5 poundsYou can fill in all the other combinations. This chart will be much easier to use than having to add up the odd plate weights in your head each time. You can just refer to the right side of the chart to pick the total weight you want, then look to left side for the combination of plates needed.
