I have one to add -- at the local community center gym in a little beach town in Alabama - very nice facility, small, most of the machines you'd expect, small weight rack, preacher curl, squat rack, smith machine, couple benches.
In walk home boy 1 & home boy 2 - these are guys who look about 17 w/ the baseball cap turned slightly as if they were cool rap artists - except they are skinny white rednecks from 'Bama (not saying people from 'Bama are all skinny white rednecks - just these guys who are posing as big hot rappers, but are more the un-rapper....)
Anyway - they spend 90 minutes walking around that gym doing the same curling motion on every piece of eqpt. I'm guessing it was "bi's nite" - but they never changed anything - all curls, all nite, all eqpt.
Whatever.
I was so tempted to suggest 21s or something. Or at least slap those silly hats off their heads & send 'em home to mama.
