We worked out with the tapes on days 5 and 6, a half hour seems to be about all we can manage. Yesterday, though, I started feeling a little more energized after working out, instead of just tired. Maybe we are starting to get a little fit! Took a rest day today, but I was out pulling weeds in the yard, and we went for a short hike as well. I am trying to listen to my body and not overdo anything. We did well though, 5 workouts in 7 days. More workouts than I have done in quite awhile! I must say that I detest jumping jacks, though. I won’t specify why, I think there may be other middle aged female readers who can relate!! Anyway, I sometimes do a few, then just jog in place for the rest. The variety of exercises on the tapes is really great though.
