Recon Ron- Essentially do a pyramid once a day for a week, then add some more reps to the same workout the next week, continue forever because it doesn't make a lot of sense. Just adding volume, set up for overtraining.
Ladder is a Pavel "naked warrior" thing. Get on bar and do 1 rep, drop, then 2, ect like a pyramid but stop 1 or 2 reps before you max out and start back up the "ladder". Could look like this 1,2,3,4,5,6,7,wouldn't be able to finish the set to 8 so-1,2,3,4,5 - 1,2,3 - 1,2, 1,2 ect. Good to spread throughout the day- do as much as possible, as fresh as possible. Great for peaking on a PT test or to just increase your max reps.
