I like the structure of the workouts and that there are two strength classes a week. I have not ventured into the CrossFit classes yet I have only taken the Metcon, circuit and strength and conditioning classes. In regards to coaches they're absolutely amazing and all very informative, they give good demos and are motivational. I love Annessa, she's so smiley and friendly and really pushes me. Brennan is so fun on a Saturday morning and is super personable. Sean Cooney is a rockstar- he takes his time with individuals and works through injuries and provides alternative moves. He makes individuals feels at ease if they have to decrease weight due to injury and makes sure everyone is doing the exercises correctly. There's a lot of free street parking and the gym is extremely clean and have a sauna and open gym times if you have a membership!

I hate working out…read more One day I was on a treadmill in my apartment building and I had just had enough. I wasn't tired or sore... I was bored. I started looking around and came across Atlas' CircuitFit (and eventually Fit360) classes. You will not get bored in these classes. You are doing different workouts sometimes as quickly as every 30 seconds. I leave these classes with sweat streaming off of my chin. The real stars here are the instructors. I've been going here for about half a year and I can't say that I've repeated a class-long routine. I'm now up to 4 classes a week (the 5:45AM/6:00AM ones). The only criticism I have is that the showers need to be cleaned more regularly. I almost put 4 stars, but hopefully this improves so I don't need to update this review.

You can probably find cheaper gyms but you will not find the high level of coaching, the well maintained equipment and the incredible community that you will get here.

I recently started F45 in Skokie and absolutely love it! Since I'm in law school on Tuesdays and…read moreThursdays from 10:00 a.m. to 8:30 p.m., with only a few breaks in between, I can't make it to the Skokie studio those days. Luckily, I found another F45 studio right off the Diversey Brown Line . I have a three-hour break between my Constitutional Law class and my evening class (which always drags). Going home isn't an option because I know I wouldn't make it back to campus. So, F45 Lincoln Park North turned out to be the perfect solution. I hop on the train after my second class, get about 45 minutes to study, and then do the F45 class. The trainers there are fantastic! Shout out to Katelyn and Ashley, who I see every Tuesday, and to Keely, who taught me on a Friday, my very first day at F45 Lincoln Park North. Thank you, F45, for having me on Tuesdays and making my day both productive and fun!

Just here to update my previous review. Still a very very good gym in the city (or should I say…read moreclub) - with everything you really could want for an entire day..,.work out? Check. Lunch? Check, swimming, tennis, golf, childcare, the list goes on. You can even get your clothes cleaned and your car washed. One drawback is the price. It is very pricey (with rates going up in 2026).., I don't really want to think about how much more I'm paying since I joined. However, I've easily spent entire days here swimming and working and working out so I guess I can't complain too much. Their spa is also great though it can get busy and in the summer the pool is a total scene (and packed). New locker rooms are underway (men's done and women's getting close) with new features and upgraded lighting and fixtures. Worth it if you don't mind paying for the amenities (and be careful with the house charge account ... it can get surprising!)
