What is the difference between the DB550, DB575 and DB5100 sets?

They differ only in top weight: 5-50 lb, 5-75 lb and 5-100 lb, all in 5 lb increments. Pick the range that covers your heaviest lifts.

How accurate are the weights?

Each dumbbell is held to a +/- 3% tolerance, tighter than standard commercial rubber dumbbells. That keeps left and right pairs closely matched.

The heads use virgin rubber rather than recycled rubber, which the maker says means less odor and longer life. Some rubber smell is normal when new.

Yes. The hexagonal heads stop the dumbbells rolling and hold them stable for renegade rows and other floor exercises.

The set carries a 5-year commercial warranty, so it is rated for gym use, not just home use.

The handles are contoured chrome shaped to fit the hand. The chrome finish gives a secure grip, though chalk helps on heavy, sweaty sets.
