the gym i go to is kind of like a diner in a small town...great food, not a whole lot of people, and the owners are friendly.
there are not a whole lot of rules and the ones that do apply are mainly for safety (speak to a dr before weight training which nobody under the age of 50 does), courtesy (rack your weights), and cleanliness (wash your damn hands after useing the crapper) that i cant argue with. Oh and its 24hr.
i've been to a fitness USA...once...when i was 15 and dont really remember much other then that, from what i hear, i dont think i'd step foot in a planet fitness or anything that has rules against doing certain lifts or makeing too much noise. get real, dudes are jacked and ready to rock, its like asking a pack of lions or wolves to be gentle and kind while mowin down on a fresh kill. we are killin the weights, not eating dinner with the royal family.
