This hexagon dumbbell is specially designed to gradually tone muscles. Its hexagonal shape keeps the dumbbell from rolling away from you. Dumbbell is based on a completely new workout technology called Dynamic Inertia, which ignites the muscles in your arm, shoulders, and chest.
Other Thoughts:If you're looking for an effective, affordable, and space saving set of high quality dumbbells, definitely purchase this item. I was on a budget and with the weight I've lost and muscle I've gained since I purchased these, I've already received my money back tenfold!
Other Thoughts:These Hex Dumbbells allow me to have all the weights I need in a small workout area. You do need to treat them more gently than “gym weights" but that's a good habit to get into anyway. They work great for P90x
Other Thoughts:I have owned and used these Neoprene Dumbbells for two weeks now, and they have performed perfectly.......comfortable to use........I have not experienced any of the issues that earlier purchasers apparently did. in my opinion this a great product.
