Re: WEIGHT TRAINING AFFECTS ON DRUMMING(advice needed)
I'd stay away from lifting heavy weight honestly. Maybe if your doing light weight/more reps it would be alright just to tone yourself up. I have always understood the bigger you get the slower you get. Plus look at the pro drummers....how many of them do you see that have arms the size of their head? I can't think of any lol. Plus trying to play and practice while being sore as hell is a B***ch!
Unless you're planning on being 300lbs, I don't think you'll EVER have that problem... and even then, it would be fairly neglible. A guy who is 150lbs and weak for his size in his forearms and fingers (or the majority of the non labourer drumming population...) will be slowed down by the weight he has to move far more.
It will take the average guy at 5'9 a good, long, hard slog of some years at training - even purely bodybuilding orientated - to reach a "mere" 190-200lbs at less than 10% bodyfat. That's not a lot of weight to lug around, but it's a lot of muscle and a conditioned frame.
Getting "arms the size of your head" takes freakish genetics and years of intense training.
Worrying about lugging around excess fat is WAY MORE of an issue than excess muscle ever could be. I know a few 300lbs drummers, and I know a LOT of drummers over 200lbs. (LEAN 200lbs guys are rare, and it takes building an awful lot of muscle to get there) Despite the horrific health issues however, the weight they need to move has a
minimal factor on their speed compared to their technique and forearm/wrist conditioning. These guys have no problem playing death metal sets. A bulky muscle guy will have even less to worry about.
The most critical thing for drumming, IMO, when it comes to weights, is avoiding injury. The wider variety of intense physical activities you do, the more chance that you could get hurt, so just like drums, refine and refine and refine that technique. I take one day of drumming a week - that's the day after I do lower back and shoulders. Not because of soreness (despite bodybuilding, I get very little of that), but because one day off is a good idea anyway, (I drum full time), and there is no better day than when delicate injury prone muscles are recovering than to take off. Conversely, after I train quads and chest/upper back, my rotator cuffs and lower back aren't hit very hard, and I can have a 10 hour drumming session the next day no problem. Much nicer to drum with a recovering chest and lats than the more delicate areas. My rotator cuffs would get very tired very quickly drumming the day after shoulders.
Rotator cuffs are delicate and get used alot in moving around the kit, so I do specific rotator cuff exercises (L-Fly's) too.
Also, in drumming we develop the flexor muscles of the forearms and fingers alot, but this can leave the extensors relatively neglected, which can lead to elbow trouble. So I recommend any drummer do finger extensions with elastic bands and reverse curls, or a form of reverse wrist curl that DOESN'T irritate your wrist joints. (I need a thick bar to safely do reverse wrist curls). These things won't add significant visible muscle to your physique or even build great overall strength, but they focus on oft neglected smaller muscles and can keep you injury free and healthy to employ the basics.
Also, there are many ways of training to minimise soreness. I do a bodybuilding routine, and have low levels of it, even though this is probably the most soreness guaranteed way of training. I spend several weeks building up to my top weights with frequent workouts (pure conditioning and technique building) before employing slow steady progression on basic exercises for a few months (1 kilo a week). No drop sets or intensifiers or any fancy stuff. Just, consistent, hard work, lots of warming up, lots of Vitamin C and veggies and fruits, plenty of protein and water. Very little soreness, certainly none that could get in the way of my drumming. It's all about a decent approach.
If you do a pure strength/conditioning routine it should be even less of an issue.
