I love my Bowflex SelectTech 552 Dumbbells! They have helped take my strength training to the next level. Using the selection dial it’s simple to adjust from 5 - 52.5 lbs. I love that I can dial up in 2.5 pounds increments; not in 5-10 pounds typical in using single dumbbells. Plus, Bowflex Dumbbells replace 15 sets of weights! Easier on the budget buying single weights and less space! LTKFind LTKhome LTKfit
