Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to pole vault [title] Select the height of the bar for your vault. [step] For your first few vaults, you should remove the bar completely to give you the most space to learn the movements of vaulting. For your next few jumps, try using a bungee cord to approximate the feeling of a pole.

Ending1: There isn't much wiggle room during this initial jump, just the ropes are flexible and can move easily and correctly. [substeps] Try to get a normal amount of rope, about 9 to 10 feet (3.0 to 4.6 m). Ending2: [title] Lift yourself up to the height of the bar. [step] Elevate one arm on the front bar. Ending3: For some sloppy jumps, sizing up the height of your vault may be more difficult. [substeps] For the kettle vault, measure two sides of the bar , 1 from the top to the bottom. Ending4: Then, once you are confident with clearing the bungee at 5 to 8 feet (1.5 to 2.4 m), place the standards (the pole you jump over) at the same height. This bar will get progressively higher as you become more confident.
