Here's something I've been doing for the past 3 os so weeks:
Early PM: Eccentric-less
PM: High volume (max rep circuits)
It's basically what we've seen from the Daryl Gee project! Works really well for upper body pressing.
To limit SNC fatigue when training larger muscle groups (legs, for example), I'll sometimes go:
PM: Neural charge
Just play around with the 3 types of workouts, you should be able to find what works best for you!
