Could you give an example of what a week of training would look like? Because training every muscle group with one direct exercise per session requires very dialed-in programming. It could very easily be argued that the particular full body approach you’re talking about requires more thinking than a bodypart split to allow progress and avoid overuse/overtraining.
Much more importantly, you haven’t updated your training log since you started this thread almost a week ago. What have your workouts looked like most recently? What you were doing wasn’t anything close to optimal for building size, so I’m wondering if you’ve adjusted your plan.
