What is a better way then just looping through everything in the workspace?

So would I loop through all the tags? And what if a new player joins?

You’d tag new humanoids as they are added.

local Game = game
local Players = Game:GetService("Players")
local CollectionService = Game:GetService("CollectionService")

local function OnPlayerAdded(Player)
	local function OnCharacterAdded(Character)
		local Humanoid = Character:FindFirstChildOfClass("Humanoid") or Character:WaitForChild("Humanoid")
		CollectionService:AddTag(Humanoid, "Humanoid")
	end
	
	local function OnCharacterRemoving(Character)
		local Humanoid = Character:FindFirstChildOfClass("Humanoid")
		if Humanoid then CollectionService:RemoveTag(Humanoid) end
	end
	
	Player.CharacterAdded:Connect(OnCharacterAdded)
	Player.CharacterRemoving:Connect(OnCharacterRemoving)
end

Players.PlayerAdded:Connect(OnPlayerAdded)
