About 10 years back the MAX-OT program advocated doing no more than 45 mins per workout, and this included stretches and plate changes. Any more, and the excess would simply be burned calories, not extra muscle mass/strength.
But if you’re on a cut, doesn’t this make perfect sense to go to an hour, or even 90 minutes?
Well that felt fucking great!! Paced myself nicely, most of my lifts went up a few reps from last week. Session lasted over an hour, but don’t know exactly.
