TaeKwonDo

So, the big boss here at my job is a master sensei in TaeKwonDo. We have our own class two times a week. There is rarely an opening and there was one this month. Three of us decided to try it. One has alot of experience, one I don't know, but he's a big guy, and me who was a yellow belt in college and smaller by 50 or so pounds.
Anyway, the sensei emailed me after tuesdays class asking me if i had ever had a stress test because i got winded during the running part of the warmup. I was not offended, but was sad. It was like a slap in the face that I have allowed myself to get so far with my health. Admittedly, I don't run. I walk, and probably need to walk faster. I tried running before, but there is a lot of stuff bouncing when someone my size runs. yuck!!!! I felt I had the stuff, just Don't run. The key here is DON'T.
Well, I decided, and prayed for strength to make it through todays class. The lead sensei wasn't there and another black belt lead us. She mentioned that they don't run unless he is there, so it should be better. I don't even remember all that we did, except jumping jacks and jumping in place and punching. Anyway, after 20 minutes of that I felt OK. Then after we started practicing forms I felt like all my energy was gone and I wasn't ready to let myself pass-out. Who wants to be that person who passes out? I can't say for sure that I was that close, but I couldn't get my heart rate back down. So I had to step out a few times to sit and collect myself.
I hate to admit it, but I might not be ready for such intense workouts. I really hate admitting that. But don't want to do too much so that it isn't even helping me loose weight. I have heard that working out past your talking point is bad for you.
Abbe doesn't want me to use this as an excuse. I see that. Jenn mentioned that it's not quitting if I find a different class that is a little less intense. I just feel bad that I can't keep up. But am ready to admit that the 1hr workout here is too much for me right now.
We shall see
