How this EMOM workout works

This 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.

Who this intermediate workout suits

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.

How to scale each movement

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.

What you need

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.

Common questions

About 15 min of working time, plus five to ten minutes of warm-up beforehand and a few minutes of easy movement afterwards.
Do I need any equipment?
No. Every movement is bodyweight, and floor space about the size of a yoga mat is enough.
Can beginners do this workout?
It is written at intermediate level, but the scaling options above let you run it at a lower intensity. Reduce the reps and choose the easier movement variations.
