I guess there are just different techniques on this, but I'm alarmed that no one is familiar with this. I assumed it was common practice. All three of my instructors have told me about this method.
To clarify, I'm not saying that these are used on a drum or on a kit. It's practice pad exercise. I'd never pull my stick up like that while playing the kit.
Anything beyond this is speculation on my part, but I don't think going to the gym will come close to working the muscles in the same way. The actual action of doing this method and these exercises with the sticks is what will develop the muscles to give you better stick technique.
I don't know Joe Morrello's technique, but I can't believe that all three of my instructors had a collective delusion about the best way to develop a good stroke.
