I found it odd that a 160 pound barbell only gave 40 units of lead, so I made the barbell weights have sensible quantity of lead . Each barbell now has an equal amount of lead based on its weight. So a 20 pound barbell has 20 lead, 160 pound barbell has 160 lead.I've also added on 2 steel for the handbar that holds the weights.
Just a simple mod, extract, drop into the Data folder and activate it in the mod list.
