First Boomer Boot Camp Week

I missed the first day of Bootcamp because of still being sore from my bike accident. However, I did make it to the second class today. I was able to do it, just kept the weights light and had some trouble following all the steps - but I know I will make it.
So are any of you in an exercise program to undo the years of not doing? What is it like? What keeps you motivated?

Boomer Camp Here I come

OK, tomorrow I start Boomer Bootcamp. It is an intense workout program to get my out of shape bod into shape. So, here I am 60 years old and ready to start an having someone direct me how to work out. My body is scared. Two days a week! Doesn't help that I fell off my bike today - again!
OK I will post again tomorrow.
