What settings make a Tabata timer?

Work 0:20, rest 0:10, rounds 8. Four minutes, start to bell. Lengthen the rest or add rounds and the session still works; whether it is still tabata depends on why you chose 20/10 in the first place.

Do I need a dedicated EMOM mode to run EMOMs?

No. An EMOM is a round timer whose round happens to be a minute: work 1:00, no rest between rounds, one round per minute of the session. Any timer that starts each round with a cue you can hear will run it, because the format lives on knowing when each minute turns. A dedicated button only types those numbers for you.

How do I score For Time on a countdown timer?

Take what is left on the screen away from the cap. A 20:00 cap finished with 6:12 showing is a 13:48. If the bell arrives with reps outstanding, the score is the cap plus the unfinished work, and both numbers belong in the log.

Can one timer cover EMOM, AMRAP, Tabata and For Time?

Yes, because the fields are always work, rest and rounds; only the numbers differ. Save each version as a preset under its protocol name, and the whole set is one tap away when the session starts.

Building protocol timers: EMOM, AMRAP, Tabata, For Time

An interval timer has never heard of EMOM. It holds a few fields, work, rest and rounds, plus a bell at the end, and it is content to stay at that level of ignorance. The acronyms on a whiteboard or in the PDF from your coach are instructions for filling in those fields. Learn the four standard translations and the fifth protocol programs itself.

Two shapes cover everything. In the first, the clock restarts every round: a cue, a block of work, a block of rest, again. Tabata and EMOM live here. In the second, there is one long block and a hard zero at the end of it, and everything inside the block is your business. AMRAP and For Time live there. Which format suits which training goal is a comparison we have made before; this piece is the step after the decision, when the protocol is on paper and the timer is in your hand.

Tabata: two numbers, eight rounds

The recipe is short enough to memorize: 0:20 work, 0:10 rest, 8 rounds. Four minutes, bell, done. On a timer with preset cards, tabata is usually among them; if yours has it, tap the card and skip the typing. If it does not, the three fields above are the entire manual.

Restraint is the harder part of the setup. Nine rounds because four minutes felt short, or 0:15 of rest because ten was brutal, and the session drifts from the protocol into something tabata-shaped. That can be exactly the right call; the 20/10-versus-40/20 question has its own article. Make the change deliberately, with both numbers in front of you.

EMOM: make the round a minute

Set the work interval to a minute, leave out the rest block, and the round count becomes the length of the session: ten minutes, ten rounds. If your timer insists on a rest value, it is zero. Everything hangs on the start-of-round cue: when you hear it, the task begins, and the part of the minute the task did not need is your rest.

Minutes can carry different tasks. A five-round rotation of swings, push-ups, squats, rows and a plank, repeated three times through, is a complete session, and the round counter keeps your place while your hands are busy. When the rotation needs unequal minutes, or the block should run longer than the stock structure allows, per-exercise timing extends the same idea. And an E2MOM is not a new feature to wish for: the round grows to two minutes and the round count halves.

AMRAP: one block, a hard zero

As many rounds as possible needs exactly one setting: a work block as long as the cap and a single round. A 12-minute AMRAP is a 12:00 block. Rest inside the block is unprogrammed on purpose; you take it when the round demands it, and deciding when that happens falls to you.

The bell carries more weight here than in any other shape, because the last rep completed before zero counts and the one after it does not. A final signal you will actually hear, over whatever is playing, is the difference between a score and a guess. Scorekeeping stays with you: rounds plus reps, written down between breaths, repeated in a few weeks to see which way the number moved.

For Time: the clock runs backward

For Time looks like a job for a stopwatch. On a countdown timer it is one line of arithmetic. Set the cap as a single work block, one round; 15:00 is a common cap for the short couplets. Race it. When the last rep lands, the number still on the screen is the time you did not use: subtract it from the cap and that is your score. Finish with 4:07 left on a 15:00 cap and you have a 10:53.

A session ends one of two ways. Reps done before zero is a time; the bell arriving with work outstanding is a time cap, logged as the cap itself, and the unfinished reps are the gap to close next attempt. Solo, without a judge or a training partner counting reps, the timer’s record is the only record, which is the same trust a garage CrossFit session runs on.

Save the translation, skip it next time

Every one of these recipes is a one-time job. Type the numbers once, save the configuration under the protocol’s name, and the format becomes a tap: your 20/10 next to your Saturday 12:00, the minute rounds next to the countdown you race. The fields take any whole-second value, so a coach’s 35/25 or a 50/10 from a physio’s sheet enters the same way as the classics; the odd numbers have a piece of their own. Each saved preset keeps its name for next time.

Cue volume deserves the last check before the first round. The beeps and the voice need a volume of their own so they arrive over whatever is playing, because every protocol above is read with your ears while the screen stays dark in a pocket. Set that once too and the whiteboard vocabulary is fully converted, with nothing left to program between the warm-up and the bell.
