Pocket singles
Singles with the hands pinned where a double under needs them.
3 × 45 seconds
Hands creeping up on double unders
Like reaching for more rope speed. Usually it arrives when you are tired.
The cue
“Thumbs to your pockets.”
What it looks like
The hands rise from the hips towards the chest as the set goes on.
Why it costs you doubles
Raised hands lift the bottom of the rope off the floor, so it has further to travel and passes under later.
The fix
The drills for it, best first. The figure is the first one, at half speed — tap it to pause.
Fast wrists
The second pass of a double comes from the wrists speeding up, not the arms.
3 × 40 seconds
Towel tuck
Pins the elbows to the ribs so the arms cannot fly out.
3 × 30 seconds
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.
