How to film a take that counts
How to film a contest take that counts: phone placement, framing, light, the right angle for each contest, and why takes are not counted.
The highest box you can jump onto from a two-foot take-off, landing on both feet and standing up tall. The box height is measured in the take, and your result is ranked on your gym, city, country and world boards at once.

A box jump is a test of how high you can get your feet, not just your hips. The tape measure decides, and the camera shows the take-off and the landing in one clean take.
Set up the box, prop your phone side-on and press record. Hold a tape against the box so the height is readable, then step back, set your feet and jump. Land on top with both feet, stand up fully, then step down. Enter the measured height in the app and submit.
The height goes on your gym, city, country and world boards at the same time, with age group, sex and weight class brackets. Height jumped depends a lot on your own height and weight, so the brackets let more people compare with others like them.
The automatic check confirms the video is unbroken. Anyone can flag a take, for example if the tape reading looks wrong. When a jump lands in a top 10 or sets a record, a referee checks the measurement, the two-foot take-off and the landing frame by frame. A jump that is not counted shows the reason and the moment, and you can appeal to a second referee.
Build up the height a few centimetres at a time, and stop if your landings get messy or a shin catches the edge. Use a box you can step down from, and always step down rather than jumping back to the floor. Squats, jump squats and short sprints all help. Test a new height when you feel fresh, not at the end of a hard session.
Only firm, stable boxes or proper plyo box tops, and the full stack must be measured in the take. Soft mats that compress do not count.
Standing up shows you landed in control. Tucking the knees high and landing in a deep squat is fine, as long as you then stand tall.
Any age limits are shown on the contest page in the app. Whatever your age, use a box you can step down from safely.
