Learn the precision jump: take-off, arm swing and a silent forefoot landing in six stages — with target criteria, a distance rule and distance before height.
A precision jump is a two-footed jump onto a pre-defined, often narrow target — an edge, a wall top, a bollard — where you land on the forefoot and stop instantly, with no extra step and no wobble. This precision constraint at landing is exactly what separates parkour biomechanically from other jumping sports: a standing broad jump turns into a jump you steer towards the landing while still in the air [1].
The precision jump is not a long jump with a target. It is a landing preceded by a jump.
And it is remarkably safe when the technique is right. On a force plate the precision landing produced 3.2 body weights of peak force versus 5.2 for a traditional landing (drop from 0.75 metres, ten men) — roughly 38 percent less, and 54 percent less in loading rate [2]. At 75 kilos of body weight that is roughly 240 instead of 390 kilos passing through your joints.
The trick behind it is time, not strength: traceurs stretch the landing to about twice the duration of untrained participants, and the knee alone dissipates around half of the energy [3]. You do not stop the impact — you spread it.
How long does it take to learn? Most people own the ground version within a few sessions; a clean edge-to-edge version takes weeks to months. That is training experience, not a study figure.
Two chalk lines on the ground, clearly inside your maximum distance. Two-footed take-off, land with the toes exactly on the second line, freeze immediately.
Milestone: 10 out of 10 landings within 5 centimetres of the line, with no extra step.
Same drill, but you stay motionless for three seconds after landing. This rule filters out everything that only looked good by accident.
Milestone: 8 out of 10 jumps with three quiet seconds on landing.
Now add the drive: arms far back, then explosively forward and up while hips and knees extend. The arm swing is not a detail — traceurs average 59.2 centimetres in the countermovement jump with arm swing [4].
Milestone: your distance grows by at least 15 centimetres versus step 1 without the landing getting shakier.
Only now an object: a kerb or a pallet, at most 20 centimetres high, with a wide surface. Forefoot on the edge, heel hanging free, knees bending, stand still.
Milestone: 10 clean landings in a row, none of them with heel contact on the edge.
Two low objects, the gap clearly inside your safe distance. Your eyes stay on the target edge the whole time, never on the gap between.
Milestone: 20 repetitions with not a single extra step, set up in both directions.
Add distance in steps of about 10 centimetres — and only then height. Height does not make the jump harder, it only makes the mistake more expensive.
Milestone: hit the target distance identically 5 times in a row before you raise it.
The precision jump looks harmless but is statistically the most conspicuous movement in the sport: in a survey of 161 traceurs the precision jump was involved in 18.8 percent of injuries and the long jump in 11.1 percent; 69.9 percent of injuries hit the lower limb, the most common diagnoses being sprains (22.3 percent) and contusions (21.1 percent) [5]. The survey cannot tell why; it is plausible, but not shown, that the jump is simply used most often.
Three guard rails:
The good news: jumping power is trainable and quickly measurable. In adolescents training parkour twice a week, the standing broad jump rose from 234 to 251 centimetres in 10 weeks, an increase of about 7 percent [7] — though in only twelve boys and without a control group. More distance means a bigger safety buffer.
This guide explains and motivates, but it does not replace supervised training. As soon as height or a drop is involved, an experienced coach or a parkour gym belongs in the picture — someone who stops you before you stop yourself.
Measure your maximum standing broad jump on flat ground once, honestly, and write the number down. Everything you then jump with height or an exposed edge stays at 60 to 70 percent of that distance at most. It sounds conservative, but it is why experienced traceurs get old: the buffer absorbs exactly the days when you are tired, the edge is damp or the run-up is half a step off. Your maximum belongs on the ground, not on the wall.
Any distance works to start — you are training against your own mark, not against a norm. For context: experienced traceurs average 282.7 centimetres in the standing broad jump, trained strength athletes 261.3 [4]. More important than the absolute number is being able to reproduce your distance within ± 10 centimetres.
In small steps and separately from height: distance on the ground first, then the same distance on low edges, then height. Jump training pays in directly — with parkour twice a week over 10 weeks the standing broad jump rose by about 7 percent [7] (twelve boys, no control group). Never raise distance and height in the same session.
Usually because you are jumping too far and the heel drags you over the edge, or because you land too stiffly. Traceurs stretch the landing to about twice the duration of untrained people and dissipate around half the energy through the knee [3]. Wobbling means you stopped the impulse instead of spreading it.
In a survey of 161 practitioners it was the individually named movement most often involved in injuries (18.8 percent) [5]. Whether that reflects how often it is used or the technique, the survey does not show; it is plausible that the jump is simply used most often. With ground progression and a distance buffer it is manageable.
No, and that is not caution, it is sequence. A round rail additionally demands arch stability and a different foot position. First 50 clean landings on a wide, low edge, then narrow, then round — and your first rail precisions at knee height, not above a drop.
