Naw.
Agree. I use them because they are cheap and no silly contracts that have upfront membership fees and you have to mail them a letter to cancel. They are open 24 hours so I can go whenever I want and there are 2 of them on both routes I can take to my job.
As for their alarm, I've only heard it go off a few time at idjits slamming weights. Never for grunting.
There's one that opened in the town near me. Thinking about checking it out. To me if you want to grunt and slam weights, get your own. You don't own them, so don't slam them around.
All that purple bothers me though.
