As I previously wrote, I froze my gym membership. I ordered a kickboxing dvd from Half.com for $8. I did it on Monday night and thought it was pretty easy....Too bad on Tuesday, I was sore!! I couldn't believe it. It is 30 mins of non-stop jumping, punching, etc. My hamstrings hurt. So, I guess it works. I was surprised Evie didn't even bother me that much while I did the DVD. I am going to keep doing it but I want to get light weights to do it with. Then I will really be sore.
