Myo-Reps are the name for the rep/set approach wherein you basically split up your set into a few mini-sets, with very small breaks in between. Something like:
10 to 15 reps, pause for ~5 seconds, another 5, pause for 5, another 5, pause for 5, another 5.
This allows you to get more volume spent near failure more quickly, but is probably not as “optimal” as just doing straight sets leading up to that volume in the near-failure zone. It’s certainly less time spent resting than the Ideal Rest Time for Hypertrophy. You may still utilize that for performing successive Myo-Rep sets, however.
Discussion on these seems to suggest they are better for isolation exercises, perhaps towards the end of a workout after doing your Big 6 Exercises-type lifts.
