I am halfway through the Physique 57 November challenge and so far I have seen no changes. Have I done every workout? No. Have I done more than 50 percent of them? Yes. So I feel like I should see SOME difference. I will take 3/4 of an inch difference. The truth is I know that just doing these exercises while they are full body and have a little bit of cardio it isn't enough for my body. I need more cardio in combination with weight training.
