I like it, Ben. You and I are on the same page. I've also constructed my own PLP v.2.0, which will begin in 3-wks after the completion of PLP v.1.0.
50 reps/day stays constant, no rep progression. Instead, load progression per rep on the pullups and lunges.
PULLUPS & LUNGES: 50-total reps
Day 1, 10-reps, +10 lbs. +20 lbs. for lunges
Day 2, 11-reps, " "
Day 3, 12-reps, " "
Day 41 will complete the process with all 50-reps performed with the additional 10-lbs. for pullups, and additional 20-lbs. for lunges. Pushups stay the same, as simple supplemental work.
Also, b/c I've fallen in love with training every day, my primary program will consist of this light, perfect form, "crush it" warmup/practice session.
Following this, select 1-2 movements, and ramp up to one heavy set of 3. My thought process is that my CNS will be exposed to every movement pattern that is important to me, EVERY DAY.
Heavy DL's, and Hip thrusts will be performed once every 2-weeks on a "wildcard day".
