I went to Blink for a really long time and it was great. Generally a basic selection of things but enough to get things done. My closest location and primary location kinda fell off the same time a bunch of LA Fitness branches opened so I switched. Definitely a big price difference but the amenities and variety of equipment add the value. I like chains so that I can change venues when things get stale or if I'm traveling for work.

Depends on what you're looking for, where you are, and what you want to spend. If you want bare bones, classes, boutique, powerlifting, competition, etc.
