I made a change in the program this week. I went back to a 3 day split. I was doing 1 set to failure - entire body mon, wed and fri. I was seeing great gains till last week and I felt like I was not finished recovering from the last workout. I had really upped the intensity too. I did miss a day once and the next time back I felt much better and seemed to be able to lift more, and on mondays I felt more rested (with 2 days rest in between). So, I am going to see how this feels aver a couple of weeks just hitting each part once every 7 days. Hopefully it wont' be too long of a rest.
But now that I am back to the split I have more time to spend on each muscle so Last night I hit the chest, tri's and shoulders really hard. It just felt like I didn't do enough since I didn't touch the rest of the body. Wierd.
