Why it matters

The Jump Rope builds your aerobic base, work capacity and conditioning.

How to do it

Intent is the point — every rep should be maximally fast, and the set ends when speed drops.
Settle into a cadence you can hold for the full effort.
Breathe rhythmically and in time with your pace.
Build the pace gradually rather than starting too hard.
Keep your jumps low and turn the rope from your wrists.

Grinding out slow reps once fatigue sets in.

This takes work off the target muscle and reduces what you get from the set.

Instead End the set the moment bar or body speed visibly slows.
Starting too fast and fading in the second half.

A fast start you cannot hold means the back half of the effort suffers.

Instead Open at a pace you could hold to the end, then build.
Tensing the shoulders and upper body while working.

Tension up top wastes energy that should go into your legs and lungs.

Instead Relax your hands, shoulders and face so the effort stays in your legs and lungs.
Letting the effort drift down whenever your attention wanders.

Coasting drops the training effect for that stretch of the effort.

Instead Check your pace regularly and hold it steady to the end.

Tempo: Hold a sustainable, repeatable pace for the target duration.
Breathing: Breathe in a steady rhythm matched to your cadence.
If you are new to it: Use intervals of easier effort to build duration over time.
Once it is easy: Add pace changes or intervals to raise the training stimulus.
