Forgot to add this:
Heard this from Bengt Saltin, a professor in sports science:
Training twice a day, and every other day, is better than training once every day.
So if your schedule permits, you could try it out.
I'm currently on an every other day schedule, although I only have one workout each day.
If time permits, I'm gonna split some of the workouts into two workouts, AM and PM.
Thing is, I have very few sets on the current powerlifting routine I'm on right now, never more than 9 sets, and sometimes as few as 3 working sets for one workout (only once or twice every third week though).
So my workouts are already fairly short, around 35-45 minutes. Splitting that in half wouldn't hurt though, I'd imagine.
Will get back later on in the fall with some kind of conclusions.
