Just before the holidays, I met up with NYC personal trainer and author of several fitness books, Danny Kavadlo, at his home gym so he could use his vast experience and skill to give Dualbell a test drive. Enthusiastically, Danny got right into things with a variety of exercises utilizing the dumbbells he already had in his gym space.
Create a new fitness product and have personal trainers try it out. That idea seems to make perfect sense to me.
