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! :-)
