after... 9 years of playing marching percussion, 7 of them on quads, I have ridiculous muscles in my lower back. Most people have very weak muscles in their lower back, which can lead to back problems later in life, so as long as you don't screw your back up while holding a drum, it's probably a positive thing.

I'm probably going to be in a wheelchair by the time I'm 30. But, I can't give up playing.
