EMOM and AMRAP workouts: what they mean, how to use them, and what little research shows

What they mean

EMOM (every minute on the minute): start a set at the top of each minute and rest for what's left. AMRAP (as many rounds or reps as possible): repeat a circuit, or one move, for a fixed time and count what you get done.

Sources 1, 2, 3

The research is thin

We found no trials of EMOM training, and one randomised trial that used an AMRAP circuit as one of its programmes. The rest are single-session lab studies of 12 to 25 experienced athletes, so most of the advice here is our own.

EMOM is easier than the same work done non-stop

With rest built into each minute, an EMOM gave a lower heart rate, oxygen use, lactate and effort than the same work done as fast as possible, and the least slowing of reps within sets.

Sources 1, 4, 5

AMRAP rewards pacing

Experienced athletes slowed their reps and spread their effort in AMRAPs, and matched for work, an AMRAP and a "for time" workout both drove heart rate to about 99% of maximum.

Sources 5, 6, 2

Use each for what it's good at

Our suggestion: EMOMs for skill, strength practice and steady conditioning, because sets broken up with rest built in matched normal sets for strength in trials; AMRAPs for conditioning and as a test you can repeat.

Sources 8, 9, 10

EMOM

Every minute on the minute. When a minute starts, you do a set number of reps, then rest for whatever is left of it: finish faster and you rest longer. Lab studies used EMOMs of up to 20 minutes, often with a different move each minute. Longer windows, such as every 2 minutes, work the same way (our description).

Sources 1, 4, 5

AMRAP

As many rounds (or reps) as possible. You set a time, 12 to 20 minutes in the studies, and repeat a short circuit with set reps, or one move, resting when you choose. Your score is the rounds and reps you complete.

Sources 5, 2, 3

For time

The mirror image of an AMRAP: a fixed amount of work, done as fast as you can. Studies call it "for time" or "rounds for time".

Sources 1, 2

AMRAP sets in strength training

In strength programmes, an AMRAP set is a single set taken to as many reps as possible, often the last set of a lift, used as a test or to set the next session's weight (common practice). People misjudge how many reps they have left, so treat it as a rough test.

Source 11

Where they come from

Both come from cross-training and high-intensity functional training, which uses varied whole-body moves over different durations, with or without rest, unlike the fixed hard and easy bouts of HIIT (high-intensity interval training).

How little research there isMixed evidence

We found no trials of EMOM training, and one randomised trial that used a 30-minute AMRAP circuit as one of its programmes. Everything else is single-session lab studies of 12 to 25 experienced cross-training athletes, so they show how the formats feel and tax the body, not what they do over months.

Sources 1, 4, 5, 6, 2, 7

EMOM: lower strain, cleaner repsEmerging evidence

In 12 trained adults, an EMOM designed to leave about 30 seconds of rest a minute (in practice they rested 30 to 49 seconds) took 20 minutes against 12 for the same work done as fast as possible. Heart rate averaged 153 against 171 beats a minute, oxygen use 31 against 38 mL/kg/min (millilitres per kilogram of body weight per minute), lactate 6.5 against 11.2 mmol/L, and effort 4 against 7 out of 10.

In 25 athletes with matched loads, EMOM caused the least lactate and effort, and jump height fell after AMRAP and "for time" but not after EMOM. In two studies of squats, pull-ups and presses, EMOM showed the least slowing of reps within sets and the lowest heart rate.

Sources 1, 4, 5, 6

AMRAP and for time: close to the limitEmerging evidence

In 23 experienced CrossFit participants, a 20-minute AMRAP and a "for time" workout with the same work both drove heart rate to about 99% of maximum and lactate above 14 mmol/L. In AMRAPs, athletes chose a slower bar speed, pacing themselves, and slowed more between sets than in EMOMs.

Sources 2, 5, 6

Sets with rest built in: the nearest training evidenceEmerging evidence

An EMOM for strength breaks your reps into small sets with rest built in, like cluster sets. In 17 studies, cluster and rest-redistribution sets gave the same strength and muscle growth as traditional sets, better speed and power at lighter loads, and less muscular endurance; in 29 studies, there were no differences, possibly with less fatigue. The American College of Sports Medicine's (ACSM) 2026 overview found set structure made no consistent difference to strength or power, with too little data to judge muscle size. None of these tested EMOM itself.

Sources 8, 9, 13

One every-minute structure in a training trialEmerging evidence

In 21 men, 12 rounds of 30 seconds of kettlebell swings starting each minute, twice a week for 6 weeks, raised half-squat strength and jump height as much as jump-squat training did (about 10% and 20% across both groups). Our kettlebell swing workout uses this structure.

Source 10

AMRAP as a training programmeEmerging evidence

In a 6-week randomised trial of 58 young adults, a 30-minute bodyweight AMRAP 3 times a week (90 minutes a week) raised aerobic fitness no more than 16 or 27 minutes a week of fixed intervals. An exploratory analysis suggested slightly larger gains in muscular endurance, about 4 more reps, with wide uncertainty. Fitness was estimated from a bike test rather than measured directly.

Programmes that mix the formatsMixed evidence

High-intensity functional training, which mixes these formats, improved strength, power and endurance in 19 trials of people aged 10 to 23, on low-certainty evidence. Across CrossFit research, few studies had a low risk of bias.

Sources 14, 15

Injuries in group classesEmerging evidence

In 100 adults followed through 6 weeks of group strength-endurance classes, there were about 9 injuries per 1,000 training hours, and 18% of people had one. Knees and backs were hurt most often, and burpees and squats were the commonest moves involved.

Source 16

Skill and technique

An EMOM gives fresh, repeated practice with rest built in. In lab studies it showed the least slowing of reps within sets, and the authors of one suggest it suits technique work and recovery days in trained people.

Sources 1, 5

Strength

EMOMs of 2 to 5 reps with a weight you could lift about 8 to 10 times (our suggestion): short sets with rest built in matched normal sets for strength and muscle in pooled trials.

Sources 8, 9

Conditioning

Alternating-move EMOMs of 15 to 20 minutes, or AMRAPs of 10 to 15 minutes (our suggestion). The every-minute kettlebell swing structure improved strength and jump height in a trial, and a 30-minute AMRAP raised fitness, though no more than much shorter intervals.

Sources 10, 7

Density

Doing the same work in less time, or more work in the same time, is a form of progressive overload for conditioning (our progressive overload guide). Write down your rounds and reps.

Fast starts

Racing through the work caused the most slowing within sets, and a perspective on pacing suggests planned rests for beginners and keeping away from failure in long AMRAPs. Start at about 7 out of 10.

Sources 5, 3

Misjudging the reps you have left

People underestimate the reps they have left by about 1 on average, and are less accurate in sets of more than 12 reps, which is where AMRAP sets live.

Source 11

Grinding to failure

Training to failure gave little or no extra muscle or strength in two meta-analyses of 15 studies each, so keep most sets 1 to 3 reps short.

Sources 17, 18

Too many reps in an EMOM

If your reps take 50 seconds, the EMOM has stopped giving you rest: cut the reps (our suggestion).

Classes and big jumps in volume

In group classes, keep your own pace: injuries most often involved burpees and squats. Sudden big jumps in hard exercise can cause rhabdomyolysis, a rare but serious breakdown of muscle.

Check with your GP first if

• You haven't exercised for some time, or have a medical condition or concerns (the NHS advice before any new exercise).
• You're inactive and have heart, metabolic or kidney disease, such as diabetes, or get chest discomfort, unusual breathlessness, dizziness or fainting when active.
• Your blood pressure is high and not yet controlled: keep breathing through every rep, and keep to moderate effort until it's controlled.
• You're pregnant: don't start a new vigorous activity.
• You have ME/CFS: NICE (the National Institute for Health and Care Excellence) advises against exercise outside a specialist programme; see our ME/CFS guide instead.

Call 999 now (911 in the US)

Stop and call 999 (don't drive yourself to A&E) for:

• Sudden chest pain or discomfort that doesn't go away: it can feel tight, heavy, like squeezing or pressure, or like burning. Or pain that spreads to your arms, neck, jaw, stomach or back.
• Chest pain with sweating, feeling sick, light-headedness or breathlessness.
• Severe difficulty breathing: gasping, choking or not able to get words out, lips or skin turning very pale, blue or grey, or sudden confusion.
• Someone who faints while exercising, or who has fainted and can't be woken within a minute, has chest pain or a pounding, fluttering or irregular heartbeat, or hasn't fully recovered.
• Palpitations that don't go away, or come with chest pain, breathlessness, or feeling faint or fainting.

Call NHS 111 (in the US, your doctor or urgent care)

Get advice the same day for:

• Being suddenly more short of breath than usual.
• Palpitations with chest pain, breathlessness or fainting that have now stopped: ask your GP surgery for an urgent appointment, or contact 111.
• In the days after an unusually hard session, especially your first class: dark, red or cola-coloured urine, passing less urine than usual, or muscle pain, tenderness or weakness far worse than normal soreness. These can be signs of rhabdomyolysis; in reported cases after spin classes, symptoms appeared about 3 days later.

Sources 25, 27, 29, 19, 20

See a GP

• Chest pain that comes and goes, or went away quickly but you're still worried.
• Palpitations that keep coming back, are happening more often or last more than a few minutes, or any palpitations if you have a heart condition or a family history of heart problems.
• Breathlessness that gets worse during normal activities or when you lie down, or comes with swollen ankles.
• A faint at any time other than during exercise (fainting during exercise needs 999).

During a session

In group classes your pace is your own: injuries in group strength-endurance classes most often involved burpees and squats. Stop a move for sharp or increasing pain, and use its easier version.

"EMOM and AMRAP are proven to work better than normal sets"Mixed evidence

We found no trials showing either beats other ways of arranging the same work. The studies are single sessions, and in the ACSM's overview set structure made no consistent difference to strength or power, with too little data on muscle size.

Sources 1, 13

"In an AMRAP, go all out from the start"Emerging evidence

Racing through the work caused the most slowing within sets, and experienced athletes pace their AMRAPs. Start at a pace you could hold for the whole time.

Sources 5, 3

"An AMRAP set to failure builds more muscle"Strong evidence

Training to failure gave a trivial or no advantage for muscle and strength in two meta-analyses, and people misjudge the reps they have left, more so in long sets.

Sources 17, 18, 11

"EMOM is easy because you get rest"Emerging evidence

With moderate reps, an EMOM was clearly easier than the same work done non-stop, but reps that take 50 seconds leave almost no rest (our reading).

Source 1

"AMRAPs burn fat for 24 to 48 hours"Strong evidence

The extra energy you use after any session (the afterburn) is about 6 to 15% of the session's own cost, and a review called its role in weight loss generally unfounded.
