Choose this one if
- You want a full dumbbell gym in the space of one pair
- You want 2.5 lb jumps at the top end, not 10 lb ones
- You want stainless knurled grips rather than moulded plastic
The detail
Twenty-nine selectable weights from 5 to 100 lb is the whole argument, and the increments are what make it a serious tool rather than a space-saver. Above 50 lb the steps are 2.5 and 5 lb, which is finer than most fixed dumbbell sets in a commercial gym — those usually jump in fives to 50 and then tens. Small jumps are how a press keeps progressing.
PowerBlock's own figure is that one pair replaces 30 sets of dumbbells and a seven-foot rack. In a garage where floor space is the binding constraint, that is not marketing; it is the difference between owning dumbbells and not.
Knurled stainless grips are the upgrade to take. The TPR option is comfortable and slick under sweat; stainless knurl grips like a barbell and, as with any stainless part, has no coating to wear off. On a 100 lb dumbbell, grip is what fails first.
At 38 mm the grip is thick — noticeably thicker than the 32 mm on the Pro 32. That is correct for heavy loads (more surface, less strain on the fingers) and harder for small hands.
The shape is the real trade, and it is worth being clear about. A PowerBlock is a nested cage, not a bar with plates on the ends. At 19.21 inches long and 7.72 inches high, the block sits around your hand, which means the bottom of a bench press and a deep lunge both have less clearance than with a hex dumbbell. Most people adapt within a session; some never like it.
The magnetic selector pin is faster than the spring pins on older designs and harder to leave half-seated — which is the failure mode that drops a plate stack mid-rep.
The Elite USA 90 is the comparison in PowerBlock's own range: less top-end weight, made in the USA.
