Get the iOS AppThis is an EMOM — Every Minute On the Minute. At the top of each minute you start the prescribed work; whatever time is left once you finish is your rest, and then the next minute begins whether you are ready or not.
A well-scaled EMOM leaves you roughly fifteen to twenty-five seconds of rest in the early minutes. That will feel too easy at the start, and it is meant to — the fatigue arrives about two thirds of the way in, and the rest you banked early is what carries you to the end. If a minute arrives before you have finished the previous set, cut the reps.
This session assumes you can already pace yourself across a full workout without your technique falling apart. The volume is higher and the rest is shorter than a beginner equivalent. If you are having to stop mid-set to recover, treat it as a signal to scale rather than a reason to push through.
Scaling is how this workout stays useful across a range of abilities. Pick the version of each movement that lets you keep moving at a steady pace, and note what you changed so the next attempt is a fair comparison.
Hollow Rocks — easier: hold a static hollow position instead of rocking. Harder: extend fully and increase the range of the rock.
Burpees — easier: step back and step in rather than jumping, and skip the jump at the top. Harder: add a push-up at the bottom and a tuck jump at the top.
Alternating Lunges — easier: hold a wall or chair for balance. Harder: switch to jumping lunges.
No equipment at all. Everything here is bodyweight, and floor space roughly the size of a yoga mat is enough. This one works in a hotel room, a garage or a corner of the living room.
Warm up before you start the clock. Five to ten minutes of easy movement plus a few light reps of each movement in the workout is enough, and it matters more on short, intense sessions than on long ones.
