Almost all gyms and jui jitsu schools require access to your credit card for monthly deductions. Good luck trying to cancel.
I train at home now but prior to covid I was training at a mom and pop type gym that had 30 year old plus equipment. You could pay with cash for three months and they threw in a month for free.
At a posh gym across town that had something 30 treadmills, all new equipment; beautiful flooring and lighting they play a different game. No cash allowed. Sign the multiple page contract electronically. Told the wife I didn't want them having access to my credit card or bank account. She went and got me a three month gift card to the place. I showed up with my gift card and they said we need your credit card. I refused and asked for the money back for the gift card. A manager came over and said let him work out here for three months. I signed the electronic contract but with no credit card they were fucked. Never took me to court or sent me a letter.
It's getting more appealing than ever to work out at home. I have an elaborate set up but truth be told you don't need it. Adjustable dumbbell have evolved from the "antique" design of power blocks. Nuobell is one example. They look like a regular dumbbell and the weight is changed from a quick click of the handle. Have an adjustable bench with chinning option/dip attachment then you could do so many exercises while storing the set up in a small corner of a room. Dumbbell squats, dumbbell lunges, stiff dumbbell dead and split Bulgarian squats are few options for legs alone.
What I have: Bench
DB bench
Squat rack
Barbell
Dumbbells
Curl bar/EZ bar
Dip bars
Pull-up/Chin-up bar
I don't feel like I really need anything more than this but might get a stationary spinning bike as well.
I cancelled my gym membership almost two years ago and don't miss it at all.
