Will my strength (or lack thereof) particularly in my forearms prevent me from getting my double strokes up to 200 bpm? To put this in context, I am one of the weakest adult males I know. I've always thought that you don't have to be strong to be fast, based on some of the kid drummers I've seen flying around the kit, but I'm wondering if I should at least build my strength up to average. Right now my open roll becomes uneven above 150 bpm.
