Question: can you jump off two feet in high jump

Answer: No, The rules for the high jump are set internationally by the International Association of Athletics Federations (IAAF). Jumpers must take off on one foot. A jump is considered a failure if the bar is dislodged by the action of the jumper whilst jumping or the jumper touches the ground or breaks the plane of the near edge of the bar before clearance. The technique one uses for the jump must be almost flawless in order to have a chance of clearing a high bar.
