Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to execute the major kicks in taekwondo [title] Position your body properly to execute a front kick (ap-chagi). [step] The target of a front kick is-not surprisingly-in front of you. Your target should be a " leg-length " away from your body for your kick to be effective.

Ending1: [substeps] Target your body with the right leg; your left leg should be bent at right angle; your right foot should be on the ground-or, if you have a knee). The target of your kick should be to the right. Ending2: In some cases, you might jump a little forward or backward to make sure that your kick lands. If this is the case, you'll also want to make sure that you have sufficient room around you to complete your front kick. Ending3: It needs to be your back leg rather than one of your heels. [substeps] Bend at the waist slightly so that your shoulders are slightly higher than your hips. Ending4: If you aren't used to moving your body, a stronger target may be a side leg. If you are unfamiliar with how to move your body into a roundhouse kick, practice with your shoulders.
