Well being prety new to drumming I cant help but notice that my left hand is so much slower than my right. I mean I expected it to be a little but slower since I am right handed but it is riduclious. I asked my drum teacher and he said what really helped was counting to 4 and playing either LLLR or RLLL. I understand it is not going to happen overnight but do you guys having exercises that you use to strengten your weak hand?
