Jump classification

Metric Jump labels each rep automatically by watching how you move into and out of the jump. You don’t tell the app your jump type. It detects and classifies in real time.

Metric Jump is a separate app and is currently in beta.

Countermovement jump (CMJ)

The default vertical jump test. Hands on the hips, dip down and drive straight back up in one motion, with no pause at the bottom.

CMJ height is a clean test of jumping ability. You’ll notice the heights read lower than a jump mat or a Vertec reach test, and that’s expected. Jump mats can be gamed by tucking the legs on landing, which stretches flight time and inflates the result. A Vertec measures reach as well as jump, so arm length and shoulder/torso mobility feed into the score.

Metric Jump is a more pure measure of direct jumping performance, tracking the rise of your centre of mass.

Squat jump (paused)

Starts from a held squat, paused for at least a second. Lower to the bottom of your dip, hold, then jump from a dead stop. The squat jump tests concentric power in isolation, removing the stretch-shortening cycle.

Tip: A common cheat on squat jumps is to add a small dip or bounce before the jump. Metric Jump catches this and labels the rep a CMJ. Pauses that wobble, or run shorter than a second, are also labelled CMJ.

Abalakov jump

A two-leg countermovement jump with a full arm swing. The swing adds drive and lifts height for most athletes. Compare an Abalakov against a hands-on-hips CMJ to see how much height your arm swing adds to height and take off velocity. Abalakov jumps require more coordination and timing than a standard CMJ.

Single-leg jump

A jump and landing on one leg, tracked per side, left or right. Single-leg tests surface left-to-right imbalances in power, which makes them useful for return-to-play screening and asymmetry monitoring. For the per-side comparison, see Composite jump analytics.

Mixed sets

Each rep is classified on its own, so one set can hold different jump types. Charts and personal bests are split by jump type.

Tip: Just jump the way you normally do or as your coach instructs. Metric Jump sorts the labels and keeps each type’s history separate.

Editing a classification

For incorrect classifications and false rep detections, you can reclassify a rep or remove it from your data set. Just scroll to the rep summary table and update any rep you like.
