So I have a similar routine (push, pull, leg/ab), but different workouts and set/rep combination
One of the cool things about the present is we no longer have to guess which exercises are most effective at stimulating muscle development.
By using a technique called Electromyography (EMG), which measures the electrical activity of muscles during exercise, we have a good proxy for how much of the muscle is being used.
Edit: so originally I had some data here that I had from I saved in my notes from years ago to refer back to, back when EMG analysis was new and articles about it not common.
Now that’s not the case, and I can’t find that specific source, so deleting that, but ultimately I think my point of using EMG analysis of best exercises to target your muscle groups as opposed to just guessing still stands, and you can review the many articles online to determine which are best for yourself.
