Im starting my 6th week of DC. The first day of chest shoulders back tris was great. I went up 3 reps on every exercise from my last workout. On week 4 I went up about 2 reps on everything. My back is seeing sick gains as I used a higher weight and still got more reps. Ive always tried to pound my back but it barely ever got sore till I tried this program and im seeing great results. My partner is also seeing the same type of gains. The stretches definitely help improve fullness and shape although I was skeptical about them at first I figured what the hell and Im happy I tried them.
