How to Save Weights? (Weightlifting sim)

Making a Weightlifting game and i have multiple weights u can buy but im also trying to make it so the weights also save so you dont lose the weights when you go back into the game but idk how to save the weights could anyone help and explain? Thanks!

local DataStore = game:GetService("DataStoreService")
local PointsData = DataStore:GetOrderedDataStore("Points")

game.Players.PlayerAdded:Connect(function(player)
    local points = PointsData:GetAsync(player.UserId)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    local pointsValue = Instance.new("IntValue",leaderstats)
    pointsValue.Value = points
    leaderstats.Parent = player
    pointsValue.Name = "Strength"
end)

game.Players.PlayerRemoving:Connect(function(player)
    local strength = player.leaderstats.Strength.Value
    PointsData:SetAsync(player.UserId, strength)
    print("Saved Data!")
end)

game.ReplicatedStorage.BuyItem.OnServerEvent:Connect(function(player,weight)
    if player.leaderstats.Strength.Value >= weight.Price.Value then
        player.leaderstats.Strength.Value = player.leaderstats.Strength.Value - weight.Price.Value
        local newWeight = weight:Clone()
        local oldWeight = player.Backpack:FindFirstChildOfClass("Tool")or player.Character:FindFirstChildOfClass("Tool")
        oldWeight:Destroy()
        newWeight.Parent = player.Backpack
    end
end)

(thats strength that im saving currently but i also want to save weights along with it)
