Help make my script look better

[PENG_LINMEME (Nameless)]

This is my code:

UIS.InputBegan:Connect(function(input, gpe)
if input.KeyCode == Enum.KeyCode.LeftShift and gpe == false then
sprinting = true
while sprinting and task.wait() do

		if character.Humanoid.MoveDirection.Magnitude > 0 and sprinting and power > 0 then

			Tween1:Play()
			character.Humanoid.WalkSpeed = Run
			power = power - 0.03
			Bar.Size = UDim2.new(power/ 10, 0, 1, 0)
			
		else 
		
			tween2:Play()
			character.Humanoid.WalkSpeed = Walk
			power = power + 0.01
			Bar.Size = UDim2.new(power/ 10, 0, 1, 0)
			end
	end
end

end)

UIS.InputEnded:Connect(function(input, gpe)
if input.KeyCode == Enum.KeyCode.LeftShift and gpe == false then
sprinting = false
while sprinting == false and power < 10 and task.wait() do
tween2:Play()
character.Humanoid.WalkSpeed = Walk
power = power + 0.01
Bar.Size = UDim2.new(power/ 10, 0, 1, 0)

	end
end

end)
