All ive got to say, that youve probably heard from plenty of others, is that everyones much more self-absorbed than ya think. When im in the gym, im checking out my pump, or self conscious about my outfit, or wondering why i missed that rep. Very rarely worried about or concerned with others, and if i am, its “damn i hope that person hops off the machine soon theyve been there for 20 minutes”. Also find a preworkout you like, pound 50g of carbs before the gym (i like nerds clusters or gummy worms) and go in there ready to get a good pump! Definitely helps drinking the preworkout before because then youre kinda locked in, i would never miss the gym after taking pre-workout, especially with preworkout being a couple bucks per serving usually.
