I'd like to, in the future, use a Push-Pull workout routine without a separate training day for my legs. In a 3-split the extra training day for legs essentially would result in something like an extra rest day before the training days for the upper body begin again.
So I'm wondering: Is a Push-Pull workout routine with 4 training and 3 rest days a week suitable to recover enough from it in order to not overtrain over time? That would be a cycle of Push, Pull, Rest, Push, Pull, Rest, Rest per week.
A little about myself and my training progress: I'm going to the gym for almost a year now. I'm a pretty skinny guy and therefore focussing on compound movements. I like my workouts to be around 60-75 minutes (including general warmup and specific warmup sets for every exercise) and I really dislike full body workout plans. Thats why I personally prefer a 2-split, which I currently do since about 4 months in an Upper-Lower-Body workout routine.
