The LifePro PowerFlow are some of the adjustable dumbbells released in 2021. In terms of adjustment system, they’re similar to the Ativafit 44 lbs models. However, they have all-metal plates rather than plates encased in plastic which is a plus. The set includes two dumbbells (25 lbs each) with their trays.

Dumbbell construction

The LifePro PowerFlow 25 lbs adjustable dumbbells feature a pretty standard construction. However, as opposed to many other models, they have more metal and less plastic. To begin with, the handles are made of steel with a chrome finish. Their grips are cylindrical, not convex as is the case for the Bowflex dumbbells. They have a knurled design in order to provide superior contact.

One of the main advantages of the LifePro dumbbells is that they have all-metal weight plates. They’re made of steel alloy and they’re coated with a black paint finish so they don’t catch rust. They do not have plastic casings as is the case for other adjustable dumbbells. This considerably improves their structural strength. However, just as for any other adjustable dumbbells, dropping or throwing them is not recommended, as they can still sustain damage. Also, even though they can withstand push-up exercises with no problem, these are still not recommended for any type of adjustable dumbbells.

The most notable plastic elements in the dumbbells’ construction are the head caps, the heads of the adjustment pins, and the covers of the selectors. These are made from a pretty durable ABS plastic material. They don’t have a super important role in the dumbbells’ overall structural sturdiness, though.

Although the LifePro PowerFlow dumbbells don’t offer a very high weight range, they’re still pretty large. They are approx. 15.6″ (40 cm) long, and 7.7″ (19.5 cm) wide. Also, when placed in their trays, their height is approx. 9.6″ (24 cm). As opposed to that, the average 25 lbs hex dumbbell is approx. 13″L x 6″W (33 x 15 cm). But nonetheless, even the shortest users shouldn’t have a problem with this size during any type of exercise.

Adjustment system and increments

The LifePro PowerFlow dumbbells are equipped with an adjustment system similar to the XMark dumbbells. It’s a pin adjustment system. Each dumbbell has a selection pin on one head which is also connected to the other head so that when you select a certain weight, it locks a similar number of plates on each head. The selection can be placed into five different slots. This being said, each dumbbell offers five adjustment settings, five different weights.

Just like for most other adjustable dumbbells, if you select the first level, the handle won’t pick up any plates. So, the empty handle weighs 5 lbs (2.26 kg). The 2nd setting will pick up one plate on each head, the 3rd setting will pick up two plates on each head, and so on. Each plate weighs 2.5 lbs (1.13 kg), so each dumbbell can be 5, 10, 15, 20, and 25 lbs (2.2, 4.5, 6.8, 9.0, and 11.3 kg).

It’s important to add here that in order to adjust the dumbbells correctly, they have to be placed in their trays. These keep the weight plates correctly aligned so that the connection elements will always grab the desired number of plates.

It’s also important to mention that since each dumbbell has only one selector, you cannot create an offset weight. Once the pin is inserted in one of the holes, the dumbbell will grab an equal number of plates on each side.


The LifePro PowerFlow selectorized dumbbells don’t come with too many accessories. The only notable accessories are the adjustment and storage trays. The trays are made from a heavy-duty thermoplastic material, slightly flexible, and designed to withstand shock, so they shouldn’t break so easily.

The trays are actually pretty necessary for the quick weight adjustment. As we’ve mentioned above, they keep the weight plates well-aligned and tight so that the selector pin grabs the correct amount every time. It is not recommended to try and adjust them while out of their trays as the selector may not grab the plates properly, they may drop from the handles and lead to damage or injuries.

The Pros

  • Space-saving – 5 dumbbells in one;
  • Sleek design which can serve as a motivation factor;
  • Metallic weight plates without any plastic for improved structural sturdiness;
  • Selectorized adjustment system great for quickly changing weight;
  • Decent weight range (from 5 lbs to 25 lbs);
  • Fairly decent micro-adjustability – 5 lbs (2.26 kg) adjustment increments;
  • No manual plate loading and unloading hassle;
  • Knurled handles for a superior grip;
  • Sturdy handles made of metallic alloy;
  • Storage trays included.

The Cons

  • The knurling on the handles may be too rough for beginners (gloves can always solve this problem);
  • Sligthly larger than hex dumbbells of the same weight;
  • Not as sturdy as fixed or non-selectorized dumbbells.


The LifePro PowerFlow adjustable dumbbell set includes two dumbbells with their trays. Each dumbbell offers 5 adjustment positions, with a 5 – 25 lbs (2.2 – 11.3 kg) adjustment range. They are selectorized dumbbells with one selector controlling both heads. Just like any other selectorized dumbbells, they help save a lot of time when adjusting weights and also save space. Due to their weight range, they may not exactly be the best choice for advanced users, but they should suffice for beginners and mid-level users.
