ok then at least you know where to get them when you eventually get the option, because DeadlyShadow is right that they are the next stage for the room workout, you just need to find the other trigger.No I never picked them up (and does not exist in my inventory) and when I go to my room and try train it says:
"I don't think I can improve my strength anymore with this" and I only have two options when I try it out.
Workout or Leave. Never had any option to add those red weights. I must have gotten that extra 0,33% elsewhere somehow.
Send me your save if you want.
