EMOM – Every Minute On the Minute
You have one minute to complete the number of repetitions. If you finish the repetitions in less than a minute, you get to rest for the remaining seconds (i.e. perform 10 reps in 45 s; earned 15 s rest).
Aim to complete all 4 Sets back-to-back without any additional rest.
The goal is to have your HR elevated for the entire 12-minute block.
