Everybody gets sore and starts to burn when they play long passages or a serious session of chop building...Is there any physical signs that you should stop practicing....

The reason I ask I have a very high pain threshold so a burning wrist for me can be dusted off and dealt with .

As far as teaching kids when they complain of being sore from chop building or excerises I think its just complaining...

By all means I dont over work them and I do give them the proper break time...
Is there anything else I can do to make sure that these muscles are over worked and my drummers face injury

To me, it's not how big the pain is, but where the pain is. Chopping is supposed to build finger, and arm muscle. There should be a slight growth of wrist muscles, but not much. If your students are having alot of pain in their wrists, and not much every where else, then you might be having a genuine problem here.
Hope that helps

Real pain should never be ignored. Some pain is good pain. Other pain is, well, not so good. The classic “burn” is usually a good thing, however, in young players, too much could damage muscle. Playing drums is like working out, it’s good to feel a little pain but too much could do more damage than good.

On a second note. Being between generations, I see from the outside. I deal with the younger generation (25 yrs old and younger) on a daily basis, teaching them how to do their jobs. I’ve noticed that a lot try to get the max for least. What I mean is that some try to put in a little effort as possible and get the maximum benefit. Sooo, watch your kids. As in instructor, by default, your probably older than they….and physically more mature. It’s OK and recommended to push your students, but also know when to hold back.

Some will complain, you have to watch those too. The best way to catch on to that, imo, is to watch for patterns of behavior. If you notice a complaint every time you push, or if something new is introduced, then you know. If they complain about it hurting and say they have a medical condition, great. Your next statement should be along the lines of “With a doctor’s note, I can fully deduce what you can and can’t participate in. Keep in mind that if the doctor’s orders prohibit you from running, we may need to place you in a non-marching position because some sets may require running or fast paced marching”

There’s also the bone pain to think about. If a student complains about writs, elbows, shoulders, or any other joint, that could be a serious sign of arthritis, tendonitis or something other.

If you have any diabetic students, feet can become an issue (I know from personal experience). With diabetes, the blood does not flow as strongly to the appendages as it should (and that’s every appendage). If the feet are hurt, one could be in serious trouble. It’s not uncommon for a diabetic to have an appendage amputated because of an injury that would not heal, thus causing infection.

Burning and soreness is good. Pinching and sharp pains are bad.

Cramps are normal and usually a sign of dehydration. Take chaffing seriously and fix the issue. I'm shorter and it's real tough if your carrier rubs in the wrong spot.

Also, do everything possible to make the drum heights and positions as comfortable for each player as possible - forget making the drums an even line.

When I chop out (rollz) I go until I can't anymore.
HOWEVER, I usually take a long break afterward.
I would recommend chopping out daily (for your line), starting easy and getting progressively more choppy.

Any real pain is bad. Pain that reaches from one place to another (like down your wrist) is bad. The key to play fast and in control is to be relaxed. Learn the difference between a good burn, and pain. Pain results from tension, and tension is a result of poor technique (ie. playing something faster than you really can, holding the sticks the wrong way, slicing, etc.).

My drum line instructor always said the burn should be in the forearm, and it should feel like exercise and use of muscles it should never be felt in the wrists. If any pain is felt in the wrists especially the left hand when playing traditional it is not a good sign and you should stop playing temporarily until the pain goes away. This is usually a good indicator that their form and technique is not correct because a lot of beginners and intermediate players often use incorrect technique and while it does not affect playing ability too much it may seriously damage tendons in the wrist. This was all told to me by my drumline instructor who had this happen to him at a young age and now must wear a wrist brace sometimes due to overuse. The most important thing i would say is to make sure their form is correct. If they are complaining about burning in the forearm that just means you are doing a good job getting their chops up to par.
