This morning I did my usual boxing class. I've not had any elbow problems with it, but given that my elbow has been hurting a lot, I was a little worried. However, it didn't bother me at all. I talked to the pro leading the class, and he agree that it shouldn't if you're punching with proper form. Always keep your elbows in at your side and punch forward; don't "flap" your elbows and punch around from the side. I generally keep pretty good form, so I guess that's why it hasn't bothered me. Good! I was feeling a little tired today during class, which I guess is no surprise after yesterday.
I have a 3.0 match this evening, so that will be the real test of my elbow. Hopefully I can play smart and win without tweaking it again.
