Park and his staff are knowledgeable and caring, and they carefully cultivate a gym culture where everyone feels like part of the same team. I'd never done any olympic lifting before, and I initially thought it was really intimidating, but they are so great about teaching safe and proper form, and not pressuring you to throw more weight on the bar than you are ready for. In any workout they are able to give you options for modifying a movement if you have an injury, or maybe just aren't advanced enough to do the "Rx" version (me). I can't recommend them highly enough!

Upon arrival we were greeted by the friendly and knowledgeable GM Candice. Her passion for the brand and offerings was palpable. She herself was a member for over a year before she took the position. Together we reviewed the cool gear, lotions, supplements, amenities as well as all the different studies (cycling, rowers, yoga, etc.). Classes refresh about once a month ensuring you don't get bored. Class sizes are limited to 3 to ensure you have enough space to safely and enjoyable enjoy your workout. Before class started we were acquainted with the infrared sauna our class would air in (on tv built into the wall). We learned how to turn off the lights, increase the volume and most importantly adjust the heat to suit our preferences (heat was set to 125 which we lowered down to about 105). Our yoga mats as well as foam roller and towels were all nicely set up for us. The class itself was ok. With the tv so high up on the wall it was a little challenging to keep an eye on the instructor without craning our necks. While we felt like we had a decent workout (each tv aired class features different people displaying different levels of difficultly) we really missed hearing music and the fun it provides - tho we were told we could bring our own in via phone or little speaker. Overall this is a super clean place with friendly staff and great membership options. Since you can come in anytime (you get special access via your phone once you become a member) it's super convenient. There's also the added fun of challenges (there were cute handmade goodie bags for past participants at the front - showing the care Candice has for her members). Definitely check this place out if you are looking for a new gym with lots of flexibility and many class options.

There's a reason every person here wrote a 5 star review…read more I came to EDX on the recommendation of two friends to talk to Angelo about individual training. I was coming off a knee injury, had a handful of other aches and pains, and felt like my training (which I had been doing consistently for years), had started to plateau. Working with Angelo has been a game changer, and the depth of his fitness and coaching knowledge is absurd. Simply put, I've made measurable, significant gains in every area of my fitness. While I don't work directly with the other coaches or attend the classes (I use the open gym for the individual training plan Angelo writes for me) everyone on staff is friendly, helpful, and most importantly incredibly knowledgeable. There's no attitude here, just the expectation that you'll show up and work hard. Additionally - I've had multiple sessions with Liliana at EDX Bodyworks (the attached sports therapy clinic) - and she's a wizard, it's a great resource to have on hand for when tweaks and injuries pop up. I've been a member of probably 6 or 7 gyms, this is the best one yet, my membership will end when Angelo and Liliana decide to retire. No matter your fitness level, if you're serious about getting in shape do yourself a favor and give the EDX community a shot.
