I've been weight training around a year and a half now, coming from a somewhat skinny-fat physique, you know, a little beer belly and skinny extremities. As of now I am looking pretty decent, 5'11 and weighing in at 88KGs. Probably around 18% body fat. I've had several people who I haven't seen in a few months comment 'have you been working out' and people at my gym who I have never spoken to, say hello, and comment that I'm getting bigger. So, my routine is working. The issue I have is that, I have been using a push-pull FULL BODY workout, one day on and one day off. I have been using this for 4-5 months, and have seen the best gains in doing it. Prior to that, I was doing a split routine, of 2 days on, 1 day off, 2 days on, and 2 days off, repeat. I switched to the full body 1 day off and 1 day on, because it felt like I was overtraining, I would wake up shattered, my sleep was getting messed up, and I my gains were super slow. I also got a few colds here and there, which is rare for me. I recently switched back to the split routine nearly 2 weeks ago, and already I am feeling knackered. I worked out yesterday and today I cannot even imagine giving it my all in the gym. I went back to the split because I feel I am no longer a beginner, and should move to an intermediate routine. So what gives, why can't my body handle 2 sessions in a row? I am eating enough calories, and on each day I train 18-22 sets total. I will list yesterdays workout below. Incline Smith 5 sets Overhead Press Machine 4 sets Chest Decline 3 sets Tricep Dbell Overhead Extensions 3 sets Tricep Pushdowns 3 sets Side lateral Raises 3 sets Facepulls 3 sets >Should I go back to the full body routine, 1 day one and 1 day off?
