Tall singles
Singles with the ribs down and the body long, so the shape holds when the jumps get bigger.
3 × 30 seconds
Knees coming up on double unders
Like tucking to give the rope room.
The cue
“Tall like a pencil.”
What it looks like
The hips fold in the air and the knees come forwards, like sitting on a chair that is not there.
Why it costs you doubles
A pike tips the chest forwards and the landing lands behind it, so you travel and the rhythm breaks.
The fix
The drills for it, best first. The figure is the first one, at half speed — tap it to pause.
Pogo hops
Teaches the legs to stay long and the ankles to do the work, with no rope to worry about.
3 × 20 hops
Wall singles
Facing a wall stops the lean and the forward drift at once, because the wall will not move.

Can the camera see it?
dulike can see this one only side-on.Film from the front or at an angle and it is reported as not checked — never as passed.
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.
