gym

What should I do ? Should I gain muscle mass or lose weight? I have 5 meals a day, 20 years old, 182 cm and 72.5 kg.

I have a weird problem. I am doing PTTP and the gym I go to has several barbells and lots of plates. However, for some strange reason they only have four (!) 2.5lb plates. Usually this is not an issue at all - I only need two at most on any given session and I am always the first one at the gym...
