I took a weight lifting class at the community college back in my 20s for two separate semesters. The teacher was cool and said even thought the class was three times a week for 50 minutes, the room would always be open and unlocked if we wanted to come in to work out a bit.
As for the gym, I would be pissed. If youre not in a contract, and dont have to pay a cancellation fee, then I would just cancel. If you can afford to upgrade to the bigger facility, i would just try it out for a few weeks and see if its even worth the extra $20.
Some gyms are extremely shady at how they do business, and you can get fucked over by the sales people. I am a member of two different gyms. A personal trainer I know was a member of five different gyms (but recently cut it down to three). It all depends on what you want. Some gyms have an great day care to get families in. Some gyms have weights that go really heavy geared towards bodybuilder types. Some gyms are more like health clubs with the amenities like pools/spas/hot tubs etc. Some gyms are basic with little to no amenities...just some cardio weights and maybe trx or something.
One gym im a member of used to charge me $25 per month...then they upped it a year later to $26, then a year later upped it to $27, and starting January of this year its now at $28. My girlfriend is a member of the same gym and has the same gym membership type as me, but she got a great deal where she paid $600 for the first 2 years and now only does 1 $100 payment a year. The other gym im at starts at about $60 for an individual membership, goes up to about $80 for a couple about $100 for a family of 3 to 5 and like $120 for a family of 5-7. I just keep both of my memberships because one is open 24 hours a day, and the other has better amenities, cleaner equipment, and fix machines quicker once they break...not to mention have certain machines that I cant find at other gyms like the back pullover machine or the seated tricep extensions or the shoulder lateral raise machine, etc.
I dont have a fancy phone and so im not paying $100+ on my phone bills which lets me have extra money to have 2 gym memberships. But I will be dropping one of the memberships soon im thinking, just to try and save even more money if I can.
