re: Looking for thoughts on my current lifting routine

I like the GZCL programs, which are basically variations on 531. You do a T1 lift, which is heavy compound, a T2 lift, which is a different compound but balanced between volume and intensity, and 3-4 T3 lifts, which are accessories focused on volume.

So if you were doing a P/P/L of GZCLP your leg day might look like this:

T1-Squat 85% of training max 5x3

T2-Deadlift 65% off training max 3x10

T3-Leg Ext light 3x15

T3-Leg Curls light 3x15

T3-Calf Raises light 3x15
