Surprised myself!
Last week I ran into a friend at the gym and we both happened to be doing legs. I had been warming up for a while and he walked up and just jumped in. I lost count of how many sets I did, but my method was wave loading: A work set of 5 reps, followed by a heavy single A heavier set of 5, a heavier single I worked up to 5 reps with 295 and a single at 365. I tried for 5 reps at 315 but got dizzy at the second rep. Yesterday, Sunday 27 SEP, I did the same on my own with new-found confidence and worked up to 295 for 5 and a single at 385. I really happy with those numbers but I feel it in my knees today. I'm working diligently to shift the pressing to my heels.
