Walking animation that uses C0 is lagging behind? Help.

Hello, there! I was trying to make walking animations for a script I was gonna run in void script builder (place 2), but it's failing to load the walking animations, and is lagging behind. Script:

local punching = false
local lerping = false
local Player = owner
local Character = Player.Character
Character.Animate:Destroy()
Character.Humanoid.Animator:Destroy()

local Torso = Character.Torso
local RootPart = Character.HumanoidRootPart
local RS = Torso["Right Shoulder"]
local LS = Torso["Left Shoulder"]
local RH = Torso["Right Hip"]
local LH = Torso["Left Hip"]
local N = Torso.Neck
local R = Character.HumanoidRootPart.RootJoint
local defRS = RS.C0
local defLS = LS.C0
local defRH = RH.C0
local defLH = LH.C0
local defN = N.C0
local defR = R.C0

local function lerp(th,go)
spawn(function()
--[[
local st = Neck.C0 --// This is the start C0 of the neck

local Go = Neck.C0*CFrame.Angles(math.rad(30,0,0)) --// This is the goal
]]
lerping = true
for i = 0,1,0.1 do --// You can also use for i = 0,1,0.1 too!
th.C0 = th.C0:lerp(go,i)
wait()
end
end)
end

function returntonormal()
lerp(LH,defLH)
lerp(RH,defRH)
lerp(RS,defRS)
lerp(LS,defLS)
lerp(R,defR)
lerp(N,defN)
end

function punch()
if punching == false then
punching = true
lerp(R,defR*CFrame.Angles(0, 0, math.rad(-30.023)))
lerp(LH,defLH*CFrame.Angles(0, math.rad(30.023), 0))

C0 animations do not replicate well to the server. Some people use tweenservice so the server creates at leats a tween between the frames in server. Else you can try sending C0 e C1 by remote event.
