I'm relatively new to the commercial gym thing and it's really not for me. Walk in get eyeballed, figure out what the fk you are going to do because people are standing and talking but left their towels on shit, this being the apparent indicator to let you know you can't use that piece of equipment..
Find a squat rack, excellent, I've deadlifted so now I like to front squat. Finish my first set to a tap on the shoulder, i remove headphones.
"hey bro, let me show you something"
I move from the rack, he gets under the bar sets for a back squat.
"see the bar goes behind your neck"
I rest my case, commercial gyms are not for me.
