I like it! Been a member there on and off over the past 3 years.

Pros: The savings with the annual rate are pretty good. Try to get one of their no-fee or "x months free" sign-up deals. If you're ready to commit to a year, it can come down to ~$65/mo, which is really good around here for a clean gym, with pretty well-maintained equipment, that also has nice locker rooms with showers and towel service, plus group fitness classes included.
Proximity to the red line is great for not having to drive.
Shocking amount of equipment packed into a small space. They recently added 2 new power racks, which is relieving some of the rush hour pressure.
The second location is clutch when the first gets too busy, and not so far that you can't just walk over on a whim.
Overall excellent group fitness instructors.
Crowd is overall very courteous in the weight room, if occasionally lacking spatial awareness when walking around.

Cons: Can be stupid busy in the after-work hours. This got better when they extended their hours again post-pandemic closures, but you're still better off going off-hours if you can, especially if you want power rack or bench access.
Second location closes early.
Expensive for month-by-month memberships.
Shitty guest policy. 1 free guest per month, and after that they have to pay the usual day pass price of $20.
No dedicated parking. I think they validate at one of the garages? But honestly, take the T or walk.
