I recently finished my first six week HST course and did the three days per week routine. Granted it was only six weeks, but I didn't feel like there was enough volume with the program (I'd consider myself an intermediate lifter). I'm thinking of upping the number of days I work out from three per week to every 48 hours. So instead of working out 18 times over six weeks (three times per week), I would get 21 workouts over the six weeks. Also, I'm thinking of upping my volume from two sets per exercise to three. Curious if one or more of these changes to the HST program might induce over training. Also, after my initial six weeks (two weeks of 15s, two weeks of 10s, and two weeks of 5s) I'm doing an additional few weeks of 5s and upping the weight. I went up in most my maxes, but not some. What is a good rule of thumb when to de-load and start back with the 15s? When I've hit a wall with all my maxes? Half? Or just keep dong 5s as long as even one exercise in my routine is increasing in max weight?
