Weird Push Up Animation

Hello, today I am trying to make a push-up system in Roblox. I had a problem, when I play the push-up animation the character seems to be in the air and I don’t understand why. Do I need to put a script on the character to stop this from happening?

Try lowering the players Humanoids HipHeight property when the animation is playing.
