Buy NowThe Bowflex SelectTech 552 is a pair of dial-adjustable dumbbells that replace roughly 15 sets of fixed weights in one compact, nightstand-sized unit. A molded plastic tray holds unused plates while a dial on the end of the handle selects the working weight – turning the dial and lifting the handle swaps loads in about 2 seconds across 15 settings from 5 lb up to 52.5 lb per dumbbell (2.5 lb increments through 25 lb, 5 lb increments above that). The tray and dial housing are mostly plastic around internal metal plates, which keeps the unit light but means it isn’t designed to be dropped – doing so risks damaging the adjustment mechanism and voids the warranty. An optional dumbbell stand is sold separately. Buyers, especially of a used pair, should confirm current recall status before purchasing: Johnson Health Tech recalled the 52.5 lb SelectTech 552 in June 2025 over weight plates dislodging during use. Within that caveat, it remains a popular first adjustable-dumbbell purchase for beginner and intermediate lifters who want a full weight range without a rack full of fixed pairs – advanced lifters regularly pressing or rowing over 52.5 lb will outgrow it.

Adjustable dumbbells replace a whole rack of fixed dumbbells with one pair whose weight you change via a dial, pin, or selector plate. They are the space-and-money saver for home gyms: a single set can span roughly 5–50+ lb per hand. The trade-offs are bulkier handles, a fixed max weight, and a mechanism that can wear or rattle.
Fast adjustment (dial or lever beats stacking plates), a wide and useful weight range, a balanced feel that doesn’t clunk mid-rep, and a durable locking mechanism. Many sets include or offer a stand — worth it, since the blocks are awkward to load off the floor.

The Bowflex SelectTech 552 remains the default recommendation for space-constrained lifters who want a full dumbbell rack’s range in one nightstand-sized footprint, and its dial mechanism backs that up – testers report hundreds of clean weight changes with no misfires, and one four-year owner reports zero mechanical failures despite frequent, often rough use. Functionality is the standout dimension: a roughly 2-second dial swap across 15 settings from 5 to 52.5 lb beats anything else at this price. Durability is the weakest and most consequential dimension – Johnson Health Tech recalled the 52.5 lb version in June 2025 over weight plates dislodging during use, and the mostly-plastic housing is explicitly not rated for dropped or dynamic/explosive reps. Buyers, especially of used units, should confirm current recall status before purchasing and treat these as controlled-movement dumbbells rather than CrossFit-style tools.
