I've been pet sitting all during the month June. I wasnt able to get to the gym, so I bought the Core Rythmns DVD's. I've been doing them for a week, and enjoy doing the work out. Its a little confusing the 1st time, but keep it up, it gets easier to catch on. You can really feel it in your abs. Believe me, I am soaking wet after 45 minutes. I use hand weights afterward also.
I just got Turbo Jam today, so I am going to give that one a try this afternoon.
