Too many just don’t think for themselfs.
Cf said many many yrs ago, If you’re not improving in some area of your training each and every wk, you’re doing something wrong.
I start people on as little as possible, then work upwards, but only go upwards if improvement is still happening.
I generally try people out for a 2 H/Intensity split per wk. And try for 72Hr recovery.
so, Mon and Thurs type deal.
Some, due to work commitments, have to do Tue/Thurs - Such a long delay from Thur-Tue (5days) that you can see Less of an improvement than from the Tue-Thurs. These people would be better off with a Tue-Thurs-Sat split, but at times, that just can’t happen.
If you’re not recovering from 72hrs rest, and you’re starting at the low end of Volume etc in training, 80% of people will start RAPID improvement with NUTRITION.
I myself prefer a Mon-Wed-Fri split for Weights if i’m looking for improvement. I can hold 1 x session per week for Maintenance for about 8-10weeks.
Speed - Max speed and Acc = Max of 2 x wk, with SE the other. Need lots of therapy to keep Posture though.
Yet, i know of people (typically beginners) who really only need 1 x Hard session per wk for improvement.
