PH3: Layne Norton's Power And Hypertrophy Trainer, Day 23
Lifting to failure isn't always the answer. Keep some reps in reserve and you'll keep yourself coming back to the gym!
I know, I know—you're strong as hell now, and you're ready to take some of these moves to failure, right?
Wrong! Those reserve reps (RIR) are in place for a reason; they help your body recover more quickly, so you can continue to move serious weight at your next workout. Take everything to failure and you'll find yourself needing six rest days per week. It's pretty hard to make progress if you're only recovered enough to get to the gym once per week.
If you find yourself crunched for time today, move some of the exercises over to your rest day.
