Legs acting up while playing animation?

I’m trying to make a simple punching animation and the problem I am having is that the legs get stuck when running the animation. They seem to somehow act up, freezing either in a default mode or some odd leg kicking out to the side mode even though I haven’t added any keyframes for the legs themselves. Can anyone see what I am doing wrong?

This is the script inside my tool:

local Humanoid = nil

script.Parent.Activated:Connect(function()
	local Animator = Instance.new("Animator")
	Animator.Parent = Humanoid
	local Ani = Animator:LoadAnimation(script.Parent.Punch)
	Ani.Priority = Enum.AnimationPriority.Action
	Ani:Play()
end)

script.Parent.Equipped:Connect(function()
	Humanoid = script.Parent.Parent:FindFirstChild("Humanoid")
end)
