You can't hold a gym LIABLE for any losses including the loss of self-esteem due to the lack of results.
I wish I could hold someone or something liable for my infinitesimal progress at the gym and my waning interest in hammer curls and reverse crunches. I wish I could blame it on my instructor's total lack of concern over my Herculean struggle to repetitively lift 4 lb. dumbbells or on the gym's ancient electricity-free equipment (I strongly suspect they inherited these from Fred Flintstone), but I can't.
My failure to fit the clothes of yore is entirely my fault. You see, I can endure displacing my bowels with 15 straight sets of ab exercises but I can't stand having to park my brain for a few minutes to run on a treadmill.
I can't survive with my brain on screen saver mode. It constantly needs to have something to process. I try to process the images of the aero dancers in front of me into useful pieces of information, but all I can think of is me on that dance floor looking like a limp cow in a herd of gazelles.
I need to learn to mentally shut down or I will lose the battle with the bulge.
