Would you consider using a longer training split if the front squat, deadlift and overhead press were to be incorporated using the layer system? For example
Day 1: Front Squat, Day 2: Bench, Day 3: High Pull, Day 4: Back, Day 5: Overhead, Day 6: Deadlift, Day 7: High Pull, Day 8: Arms
I don’t like it… two many focus lifts and too much negative carryover. That is the number one mistake people make: focusing on too many different lifts. Not all lifts are of equal importance. That doesn’t mean that you cannot do more lifts than what you focus on, just that not all lifts deserve their own day.
A good example is olympic lifters (especially Chinese and Russian systems)… they only have two focus lifts (snatch, clean & jerk) some would argue 3 (back or front squat). But they do more lifts than this. For example in the Russian system front/back squats, RDL, push press, behnind the neck jerk, snatch pulls, clean pulls, etc. are used. But they are not main lifts.
I personally do not like doing squats as a layer exercise but rather do them as an assistance exercise after high pulls. Deadlift (or the Dead-Squat) lends itself better to the layers, BUT I still prefer to do it as an assistance exercise after a second high pull session because true layers on the deadlift are devastative on the nervous system.
Something like this would look better to me:
DAY 1. High pull (layers) + Front squat (3-5 sets of 4-6 reps)
DAY 2. Bench press (layers) + Dips (3-5 sets of 4-6 reps)
DAY 3. High pull (layers) + Deadlift (3-5 sets of 2-4 reps)
DAY 4. Overhead (layers) + Overhead supports (3-5 sets of 6-9 seconds)
DAY 5. Back
DAY 7. Biceps and abs
