Here’s a Unique Training Split Separating Anterior & Medial Delts
Question: What do you think of this training split?
DAY 1 Chest, Front (anterior) Delts, Triceps
DAY 2 Back, Biceps, Rear Delts, Side (medial) Delts
DAY 3 Rest
DAY 4 Legs, Abs
Rest for 2 – 3 more days and repeat. James K./via bodybuilding.com forum
Answer: That’s actually a pretty good option! That takes into account that the function of the anterior delts is practically the same as the upper (clavicular) pecs.
You would just have to keep in mind on this training split not to do exercises that hit both the anterior and medial belts significantly in one movement like (arguably) Arnold presses.
It especially makes sense to train the rear delts on Back day because the function of the rear delts is extension of the humerus, which is likewise a function of the lats.
I give you an a for putting your thinking cap on!

As you previously mentioned in one of your articles I am getting some interesting results by including regular push ups almost everyday short of failure of course. I have also noticed that my arms seem to respond better to low volume done more often like 3 to 4 time a week versus the usual once a week training with 12 sets for both bis & tris. And I am now definitely convinced that calves can be trained with low volume almost everyday switching exercises around since people are finally noticing them. So my next question is why wouldn’t the rest of the body like chest, back and legs benefit from low volume 3-5 sets more frequently which would translate in a full body workout. But my understanding is that you are not a pro full body training guy for complete hypertrophy development. Thanks and keep up the great work.
