Planet Fitness can eat my ass. Fuck their entire organization from top to bottom. Whoever came up with the "Lunk" think should fucking kill themselves.
From a business standpoint, it's brilliant. How else are you going to lure in the fucking fatties that are going to buy a membership and then never show up? The LAST thing that you want is dedicated lifters that consistently show up and put wear and tear on your shit.
In almost any big-box gym, less than 10% of the membership will show up in a 30 day period. 10 years ago, I belonged to a Gold's that had a lot of serious lifters. People I saw day in and day out. Talking to the membership director, he said that they had over 5000 monthly paying members and in any 30 day period, only 600 came. Think about that, just once a month shaved the crowd from 5000->600. If all the members showed up one day, the place would have to close.
If he could have found a way to cancel the membership of those 600, he would. Why not? They represent ALL of the costs and 12% of the revenue. They are a poor ROI.
