Double-under rhythm trainer
Single, single, double. Hear it before you jump it. Pick a pattern, press Start, and let a stick figure do the tripping for once.
The trainer needs JavaScript. Without it, say it out loud — it works just as well: single, single, dou-ble. The drills are below.
- Single1 rope turn
- Single1 rope turn
- Double2 rope turns
- Double2 rope turns
- Single1 rope turn
The lit box is the jump happening now. The beats are evenly spaced to keep the pattern easy to hear — real doubles hang in the air longer than singles, so this is the order of the jumps, not their timing.
Ready. Press Start.
Off unless you turn it on. A single is one low tick; a double is two higher ticks, one per rope turn. On screen, the same thing: the lit box says Single or Double.
Paused
Heard it? Now try it with the rope, at whatever speed feels comfortable — the drill steps below are the real instructions.
A 10–30 second clip gets you a count, the one thing to fix, and the drill for it. The video stays on your device — it is read in the browser, never uploaded. The rope is too thin and fast for a camera, so rope counts are estimated from how long you are in the air.
The link holds the pattern and the speed, and nothing about you. Opening it sets the trainer up; it waits for Start.
Playing a rhythm is not a set: nothing is saved, counted or moved on the ladder. No account, no camera, nothing to download.
The pattern, in plain words
A single is one jump, one rope turn. A double is one jump, two rope turns — so you jump a bit higher and flick a bit faster. Single-single-double puts two easy singles between each double, to reset your rhythm. Double-single cuts that to one. When the single between doubles disappears too, you have unbroken double unders.
The beat here is a demonstration. There is no correct speed for everyone — rope, height and legs all change it — and keeping up with this page is not evidence you can do the movement. Follow the drill steps at a pace that feels comfortable.
The drill: single, single, double
The classic bridge: two singles to reset the rhythm, one double, and round again.
- Single, single, double, single, single, double — no stopping.
- Keep the singles bouncy; do not hop high on them.
- When five cycles feel easy, go to one single between doubles.
How much: 5 × 5 cycles.See the single, single, double drill animated.
The drill: double, single
One single between doubles: nearly unbroken, with a breather built in.
- Double, single, double, single.
- The single is quick and small — a reset, not a rest.
- Drop the single when the rhythm holds.
How much: 4 × 10 doubles.See the double, single drill animated.
Want a cue for your own jumping? Film 10–30 seconds and dulike counts the jumps, names the one thing tripping you up, and hands you the drill for it. The video stays on your device, and rope counts are estimated — a camera can't see a speed rope.
A demonstration, not medical advice. Warm up first — calves and Achilles tendons are what double unders break, and they break cold. Build volume slowly, and stop if something hurts rather than aches.
