How to add an interval timer to a fitness stream

People following a workout on stream cannot count your rounds for you. A phone timer on the floor tells you where the class is; it tells nobody watching.

How do you add an interval timer to a fitness stream?

Set a screen’s clock to Intervals, choose the work and rest lengths and the number of rounds, and use the band layout so it runs along the bottom while you stay in view. Rotating lines under the clock carry your cues, and the rounds move on by themselves.

Work and rest rounds, with the coaching line changing while the clock runs.

What you’ll build

Work and rest rounds counting down on stream by themselves, with the round number and your cue, and you still on camera.

Step by step

  1. 1

    Add your Kloot overlay to OBS once

    One browser source. The timer lives inside it.

  2. 2

    Set the clock to Intervals

    Choose the work length, the rest length and how many rounds. 30 seconds on, 15 off, eight rounds is the default.

  3. 3

    Write your cues

    Add rotating lines under the clock, such as the move and a form tip, so the screen says what to do as well as how long is left.

  4. 4

    Pick the band layout

    The band runs along the bottom of the frame, so the person on the mat stays in view while the rounds run.

How screens run a whole stream

One key each carries the show’s arc — Starting Soon before you go live, BRB at the break, Ending at the close. Here’s the loop, and what each side sees.

  1. Before you go live· step 1

    Fire Starting Soon, then start the stream

    Press the Starting Soon key before you hit Go Live in OBS. The scene covers the whole canvas — your title, subtitle, and an optional countdown — so early arrivals see a show warming up, not your desktop or a frozen game menu.

    You: Press Starting Soon
    Overlay: Full-screen scene + countdown
    Viewers: Sees a show about to start
  2. Show time· step 2

    Press again — your scene was under it all along

    When you’re ready, the same key clears the screen. It fades out to reveal whatever OBS was already showing — game, cam, everything. You never built a second OBS scene and you never switched one.

    You: Press it again
    Overlay: Fades out to your scene
    Viewers: The stream opens clean
  3. Breaks· step 3

    Tap BRB — it covers everything instantly

    Door, food, bathroom: one tap (your phone deck works from the kitchen) and the BRB scene covers the entire canvas in one press — game, cam, and all. Set a countdown and it can even clear itself when you’re due back.

    You: Tap BRB from your phone
    Overlay: Covers the whole canvas
    Viewers: Knows you’ll be right back
  4. Wrap up· step 4

    Fire Ending to close the show

    The thanks-for-watching scene holds the screen while you say goodbyes, plug the socials, and send the raid. Screens are one-at-a-time, so firing Ending swaps out anything else — then you end the stream on a produced note.

    You: Press Ending
    Overlay: Thanks-for-watching scene
    Viewers: A clean outro, not a hard cut

When a full-screen scene earns its press

Every stream has moments the camera shouldn’t carry alone. These are the ones a screen covers:

The pre-stream ramp

When: You go live a few minutes before you’re actually ready — and viewers arrive early.

Why it works: A countdown screen turns dead air into anticipation. Notifications land, the room fills, and you finish your setup behind a scene that looks deliberate.

Breaks without dead air

When: Bathroom, door, food delivery — the two-minute step-away every stream has.

Why it works: One tap covers the room: game, cam, and desktop all at once. Nothing awkward stays on screen, and the countdown tells viewers exactly when to drift back.

Technical difficulties cover

When: The game crashes, audio drops, or a capture card picks tonight to die.

Why it works: A calm, branded “hang tight” screen beats a frozen frame. Viewers stay seated while you fix it, instead of assuming the stream is over.

The outro that holds raiders

When: End of stream — you’re saying goodbyes, plugging socials, sending or landing a raid.

Why it works: An ending scene keeps a produced frame on screen through the whole wind-down, so the last thing anyone sees is your brand, not a hard cut to offline.

The scenes you can run

Starting Soon, Be Right Back, Stream Ending — every preview below is the real full-screen renderer with its countdown ticking, scaled down, not a mockup.

Starting Soon — the pre-show hold

The countdown that turns early arrivals into an audience.

Fire it, go live, and finish your coffee. The purple sweep, your title, and a live 05:00 countdown hold the screen while notifications bring people in — by zero you have a room, not an empty chat.

One key up before you go live
☕
Be Right Back
Grab a snack — back in five
05:00

Be Right Back — the break cover

One tap covers everything — game, cam, desktop — instantly.

“Back in five” with a ticking timer reads as a promise, not an absence. Set the countdown to auto-hide at 00:00 and the stream uncovers itself the moment you’re due back.

Thanks for Watching!
See you next time

Stream Ending — the goodbye

A produced close that holds the room through the wind-down.

“Thanks for watching” stays up while you wrap, plug tomorrow’s stream, and send the raid. Retext the subtitle to your schedule once and it’s one press at the end of every show.

One key closes the show

It covers everything — that’s the point

Your Kloot source sits on top of your OBS scene, so a screen hides the whole canvas in one press — and one more press reveals the game that was under it all along. No scene collection, no switching.

Common mistakes to avoid

  • ✕Using the full-screen layout for a working set, which covers the person demonstrating the move.
  • ✕Writing one long cue instead of a few short lines that change while the round runs.

Frequently asked

Do the rounds move on by themselves?

Yes. Work becomes rest, rest becomes the next round, and the screen shows which round you are on until the last one ends.

Can I have no rest at all?

Yes. Set rest to 0 and one work block runs straight into the next, with the round markers still counting.

Can I count reps as well?

Yes, with a counter beside it. Open your deck on your phone and press +1 between reps.
