They say nobody is paying attention to you in the gym but that is patently untrue because I am always people watching the few time that I am there. When you don't know how to work out you feel like the stupidest guy in the world but if you go with your friend then feeling stupid becomes having a laugh. For example you can do isolated calf raises one leg at a time and balance on each other's shoulders. You can do bicep curls in sync and giggle together. Your friend can show you how to do a lateral raise and you can whine about it but that's fine, you are just learning and spending time in good company. Everyone should have a gym buddy who teaches them a few random exercises that don't really apply to their physical needs
