progress won't be perfectly lateral regardless of which you choose. if you go with doubles to triples you'll still stall and get frustrated. if you want to get better at push press, do mostly push press. or, listen to pendlay because he's an actual expert.
Here is the
sourceit doesn't end at doubles and triples, progress goes 6x2 one week, then 6x3 the following ... up to 6x6 by the 6th. I actually got there once even when i was cut to sub 75kg! THat was a year ago and i think partially it was b/c I had accepted a mediocre squat and i had more recovery resources available? im in a similar position now with my squat decided to vanish so i may just priotise upper body instead of freakign otu and getting down, im sure squat will come back eventually ..
tbh, now that im on the ohp 5x5 wagon, im even tempted to just stick with it and see where THAT goes .. heh, which is what i did today!
have decided though that while my push press is WiP .. i will consider using the btn variant as my strength builder if that one is easier to do technically correctly and if teh normal one ever gets good enough technically i can just switch over, otherwise no harm done ive got a decent compromise in the btn variant. It's not as sexy but 100kgx5 btn power press is still an okay goal to work towards
