Bowflex SelectTech 552 Dumbbells
Versitile dumbbells for strength training. You can move the dial to select any weight you want to use for your fitness level. Weights adust from 5 to 52.5 lbs. Both my husband and I use them with great results. Another good thing is that you can set them to the highest setting, when not in use, so little children cannot pick them up and hurt themselves.
