get used to it... it takes a toll on your body... drum corps is whole other issue, i am 25 and feel like im 50 getting out of bed in the mornings, i have major back issues, and knee problems. 6 years div1 with a 32"bass was fun but man it still hurts.. who ever came up with the idea to make a bottom bass player hump a 32" bass at 206+ was a master of his craft. lol just kidding man it hurts but im not complaining... You get used to it first couple weeks its gonna be killer. but my best advice is to not develope bad habits such as:
1. Leaning backwards(arching you back backwards) to relieve the stress it feels good then but causes some serious damage.
2.Leaning forwards all the way (bent over) drums hanging or touching the ground will damage you. Also when you goto upright yourself you are dead lifting 35+- lbs with your back... not good!!
3.Not rolling your feet or being on your toes in crab or back march (or whatever your style may be) there is method to that madness along the lines of the drums dont bounce which will save your back.
4. #1 problem I see drummers do and I used to do it myself.... DO NOT HANG YOUR DRUMS FROM THE BACK OF YOUR NECK! Drummers have a habit of lifting the carrier off their shoulders and letting the back bar sit on the back of their neck.... that is not good!!! probably the worst thing in this list other than the dead lift.
5. any other weird posture other than a straight back will hurt you in the long run. You will find ways that feel good for temporary relief but it most likly will cause major damage to you in the long run. Almost like eating something really tasty the better it taste the worse it is for your body (trust me i weigh 260)....
All in a lil mineral ice, helps when you goto bed, and a heat pad. NO ICE!!!!
Just my 2 cents.... Also dont let people give you beef about your size I have a kid on my indy line who is smaller than you in weight and humps a 38 pound set of
Dynasty big boy six pack tenors better than anyother able bodied person. Also have a snare player even smaller than him and SHE runs laps around our snare line even though the "Shorty" snare pretty much bangs her knee caps!!! in case your wonder no im not marching the worlds smallest drumline out here or a circus freak show. They are some of our best players hopefully they stick around for WGI season. Once again just MY 2 cents.
