Great question

And one that we took into careful consideration BEFORE we redesigned the Weighted Hands grips and add on weights.

This is by far the most common questions asked by Heavyhands and Weighted hands enthusiast.

And the answer is YES.

Both the old Heavyhands and new Weighted Hands fit together like peanut butter and jelly.

All you have to do is twist either your existing Heavyhands weights to my new ergonomic grips.

Or twist my add on weights on to your old Heavyhands foam handles.

However, my ergonomic grip Back straps will NOT fit or replace your old broken Heavyhands back strap.

It may be time to upgrade.
