Im going to say this. I did the same thing and couldnt wait to go workout just to see some improvements. You will see the same gains if you cut it down to 4-5 days a week of lifting with supplemented cardio. Your body is not having time to repair and your tearing down all this new muscle but not giving it time to heal. I lift 4 days a week with 5 days cardio and am 190 lbs. I can honestly say those who lift 7 days a week will not see half the gains i see in 4. And while lifting after each set I take a 3-5 minute break so some of that muscle can repair and once I hit the weight that shit tears right back down. So moderation is key when doing this dude your overworking your body
