Training 7 days a week - people say you shouldn't do this but I'm literally addicted to it. I never hit the same muscle groups 2 days in a row, but I am seeing a change in my body at least every 2 days. I just think, slaves would bust their asses from sunrise to sunset everyday, so a rest day isn't a must. People say they can't see results till months. There is a zone that most people don't get in. If you want to sculpt your body it's going to take a lot of pain that you have to push through. When performing a set and it starts to hurt, your body naturally wants to stop. You say to yourself ok I got about 4 reps left in me, but then you end up doing 12 more. You get in to a zone where you don't feel pain, you just keep going till failure. You are a lot stronger than you think. Your muscles tighten up and this feeling is like my fix. When you get into that zone you don't even hear the words of the music playing. It becomes background noise. Your focus gets locked in on your workout. Your body conditions itself to push through pain, this is why I always superset as well.
