Most of what we see in the fitness world is bodybuilding which is not what an athlete and especially a drummer should be doing. Increasing muscle size will not benefit your playing, who would make a better drummer - Arnold Schwarzenegger or Bruce Lee? Proper workouts focus on improving function, not beach muscles which can actually hinder your performance. You do not play faster rolls due to bigger muscles, this comes from better motor control from practice not weighted sticks.
You do not need a gym membership to get healthy, less than 15% of the population belongs to a gym and many of them are not healthy. Using simple home equipment or simply just your body weight is very effective if performed the right way. Most of the Drummer’s Rx programs are designed using minimal equipment at home, if you go to a gym that is great and will be addressed but not essential to our system. None of the Drummer’s Rx programs require expensive equipment or vast amounts of time to see results.
