Approach at a 45 degree angle, jump off in front of the vaulting box with the leg facing away from the wall and push off from the wall over the box with the leg facing the wall, landing on the soft mat.
Make it easier:
To improve the grip on the wall, a small soft mat can be set up at the point of contact with the wall from which the participant can push off.
Variant I:
After the jump, support yourself on the vaulting box with the hand facing away from the wall. Walk over the vaulting box with your feet.
Variant II:
After the jump, support yourself on the vaulting box with your hand facing away from the wall. Walk along the wall with your feet.
