I think the 2 major factors in fatigue were from
A) low caloric diet, and not right balance of Pro-Carb-Fats B) 3 full body workouts per week at high repetitions without having enough recovery time, for too long of a cycle i.e.10 weeks. My workout consisted of Squats, Deads, Bench, Rows, Lat pulls, and Iron Cross (?). M,W,F 3 sets of 15-20 reps. Complete workout was approx 45min-hour cycling 2 people. Basically I burned myself out but my main goal was to burn calories. It was more like a cardio workout than resistance training, but it did the trick. Looking back, I just probably went about 2 weeks too long without changing things up. My starting weight was 222+/-2lbs. currently 198+/-2lbs. I changed everything up 2 weeks ago, splitting up body parts, still M,W,F. Now I cycle between 4 sets of 8-12 reps one day, and 4 sets of 4-6 reps the next, for each body part, with corresponding weight increases for low rep days. So far I feel absolutley wonderful, and strength has increased more than I would have expected.
