While Bowflex is a well-known brand for adjustable dumbbells, FitRX offers a more affordable alternative. Currently, you can purchase a pair of FitRX Adjustable Dumbbells for just $196 (or a single dumbbell for $98). Compared to the Bowflex 551 set, which costs over twice as much, this is a significant savings. Walmart even provides free shipping, though be prepared—the package weighs over 100 pounds.
Pair of FitRX Adjustable Dumbbells (52.5lbs Each)

FitRx 52.5lb Adjustable Dumbbells (Pair)
$398.00 (Save 51%) $196.00 at Walmart
The FitRx dumbbells adjust smoothly from 5 to 52.5 pounds across 15 weight increments (5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 30, 35, 40, 45, 50, and 52.5 lbs) with just a dial turn. Their compact design eliminates the need for multiple dumbbells, saving space. While a stand isn’t included (available separately for $249), any sturdy surface will work.
Though I haven’t tested this specific model, adjustable dumbbells like these typically share a durable, straightforward design. FitRx’s version has earned strong reviews on Walmart, with over 5,000 users averaging 4.5/5 stars.
Ideal for home workouts with limited space, these dumbbells provide versatility for full-body exercises. Pair them with bodyweight movements like push-ups or squats for a complete routine without crowding your home gym.
