Power for Powder

My new thing at work is to put on classes for 8-10 people. I just started up a 6 week ski and snowboard strength and conditioning class called Power for Powder. Check out my flier on Facebook. I know, it sounds pretty hard core right? I never pictured my self doing anything like this but hey, I'm jumping into it with both feet and hopefully I'll land upright. I was always such an advocate that as an Athletic Trainer I can't help you get fit but I can help you if you get injured. Well I guess technically I can take my education and try to do both. So the first day of my class was today. I was a little worried that I would not have a lot of people show up but the class is full and I even have a waiting list! We started with some dynamic stretching and then did some fast pace circuit training and then a little section of the class I like to call "last run endurance". Every one at work kept asking me if I was nervous which is weird because you would think I would be but I never really was. I kept it cool all during the class and hopefully I was motivating and positive and gave every one a good work out. The only thing is, now that I am home, I am totally freaking out about the class. Did every one like it? Will they show up for next weeks class? Did I explain things well enough or did I go through everything too fast? Oh man. And yes, now I am nervous that I have to do it all over next week. What is wrong with me?!
