Bouncy singles
The rhythm every double is built on: small, quick, and the same every time.
3 × 45 seconds, 30 seconds rest
Uneven rhythm on double unders
Like chasing the rope, or it chasing you.
The cue
“Same bounce, every bounce.”
What it looks like
Some jumps long, some short, with no pattern to it.
Why it costs you doubles
A rope turns at a steady speed. A jump that is not steady too meets it at a different place every time.
The fix
The drills for it, best first. The figure is the first one, at half speed — tap it to pause.
Side swing and jump
Hear the rhythm first: the rope slaps the floor, you jump. No rope to trip over.
3 × 30 seconds
Single, single, double
The classic bridge: two singles to reset the rhythm, one double, and round again.
5 × 5 cycles
Can the camera see it?
dulike can see this one from any angle.
It watches your body, not the rope: a speed rope is a few millimetres across and faster than a phone records. Whether a jump was a double is estimated from your time in the air, and how it works shows every threshold.
Not sure this is you? Film 10–30 seconds of skipping and dulike will check — along with the other faults it can see, and the one to fix first.
