With help from a few folks here, esp Kenny Croxdale, I've established that pause variations are my best bet to increase my numbers on the main lift.
Specifically though I'm wondering if I should hammer my legs with one more exercise.
For me, Sunday is deadlift day. Squats follow on Thursday after 3 full days of lower body rest. Deadlifts occur again after 2 full days of lower body rest.
If I add another intense leg exercise on Squat day that gives me only two days before deadlifts, which might not be enough. That was the source of my "is this too much" question.
Or I could add another intense leg exercise on Deadlift day. That leaves more rest until squats day, which may be better than hammering on squat day.
