Thanks Mind Power and Gracey for your advice! I will take a little bit of each one of your advice and try it at home. I have only been able to go to the gym either Sat. or Sundays. So whether I like it or not I have to start working out at home. I don't mean to sound naïve but first time I heard of circuit training and for sure I will try it. I have a punching bag at home and when I'm in the mood I do kicks and punches (I used to do martial arts before) but I get bore of doing the same thing. Now that I'm aware of the circuit training I will try to incorporate everything into it.
Oh and Gracey thanks for reminding to stretch!
