Learn the squat vault: prerequisites, build-up from squat-on to the box vault, a controlled landing and the mistakes that leave you stuck on the apparatus.
The squat vault is a support vault in which you run up, take off with both feet, place your hands on the apparatus, pass your tucked legs between your arms and land behind it. It is the first jump in which you go over an obstacle and thus the ticket to the straddle vault, the piked vault and later the handspring vault.
The honest answer to "How long does it take?": with regular practice many adults manage the squat vault over a low box in a handful of sessions. The high, fluent squat vault over a buck or lengthwise box takes longer because run-up, take-off and hip height must fit together. That is an experience-based estimate, not a study figure.
What you should know beforehand: the vault is not harmless in gymnastics. In a children's-hospital review of 163 injuries in young male gymnasts, vault was the second most common apparatus after floor (20 percent of injuries) [1] — the figure comes from a clinic and not from a random sample (TRANSFER to you as an adult). The Swiss Youth and Sport (Jugend und Sport) material stresses that helping and spotting "must not be improvised" and are among the main tasks of the teacher [2].
Six to eight steps, steadily getting faster. Shortly before the board a small hop, then a two-footed take-off. The arms swing along. Milestone: ten run-ups in which you hit the same take-off every time.
Hands on the box, legs into a squat between the arms, landing on the box. Repeat until the sequence hands – hips – feet is in your feeling. Milestone: five squat-ons, each time hands first and feet cleanly in the squat.
From the squat on the box jump off in a controlled way and land softly. This trains the landing separately from the flight phase and builds confidence. Milestone: ten soft landings, knees over feet.
Same run-up, hands on the apparatus, legs through between the arms. The spotter stands at the side of the apparatus and grips only as agreed and practiced beforehand. The hips must stay above the hand line. Milestone: five squat vaults in a row without your feet touching the box and landing on both feet.
First the box one level higher or the buck at medium height. Then the distance: mat further back. Milestone: three clean squat vaults per height before you touch the next.
The surprising trick: practice the landing separately before you put the vault together. Jump off the box ten times and land softly, knees over feet. Only when the landing is a habit does it stop costing you attention in the full vault. That is a practical tip from training, not a study finding.
Through build-up: run-up with board, squat-on onto the box, controlled jump-off, then squat vault over a low box with a spotter. Only when you land cleanly three times do you increase the height. A video from the side shows whether the hips stay over the hands.
In the squat vault you pull the bent legs through between the arms, in the straddle vault you take straight legs past the arms to the side. The squat vault needs less flexibility and is therefore usually the first vault, the straddle vault follows.
So low that you clear it safely without touching it with your feet. For many a crosswise box at its lowest height is enough. Height is not a goal but a result of control. Three safe vaults per height, then one level higher.
Usually momentum is missing or the hips stay low. The take-off from the board must be strong and two-footed, and the shoulders belong over the hands. Practice the squat-on until the feeling for hip height sits, and let an experienced person spot you.
