Ask any serious bodybuilder; free weights are hands-down the best tools for increasing your strength and muscle mass. They open up a huge range of exercises and, as opposed to machines, engage a lot of additional muscle groups to keep the balance.

Each muscle group requires a different weight, and with your Ativafit® dumbbells, you can select just the right amount in seconds. You can literally put your progress on speed dial. Simply twist the secure lock-in dials and select the desired weight within seconds. Any remaining weights will be left in the base plate.

Giving you the versatility of 6 sets of standard dumbbells, your Ativafit® set saves you on the initial outlay cost as well as being much more compact to store! With superior design and build quality, it should come as no surprise that Ativafit® are leaders in the U.S. market. While other adjustable dumbbell models have a plastic locking system, Ativafit® employs a secure high-tensile steel design.
