How I Hurt My Back and How Not to Do Multiball
I think I hurt my back shoveling snow on Sunday or Monday. Because of snow and icy roads, I didn't do any serious coaching from Sunday to Tuesday, other than a one-hour multiball session on Tuesday, where I probably aggravated it. On Wednesday, when woke up, my back was in agony. I did a one-hour multiball session, but had to cancel a one-hour private session. Today I had 3.5 hours of coaching scheduled, but due to the snow (5-8 inches expected, it's coming down pretty hard) they are all cancelled. If not for the snow I'd have had to cancel them anyway.
I think my new mattress is also a culprit - it's not firm enough. Rather than buy a new mattress (again), I just ordered an extra firm mattress topper. Hopefully it'll be firm enough.
I'm probably going to cancel all my coaching on Friday as well. I'm not yet sure about Saturday - I have two hours of private coaching and a two-hour multiball session scheduled. I'm almost for certain going to cancel the private coaching for that day. We'll see about Sunday. Most likely I'll cancel all private coaching that day (four hours), but teach the two 90-minutes classes I have scheduled.
When I feed regular multiball, it doesn't affect my back too much. The problem is feeding backspin. When I do this I tend to drop my right shoulder and rotate my back into it - ouch!!! Right now I can't feed backspin without aggravating the back. I had to stop feeding backspin in the session yesterday.
