Peter Sun’s class on Sunday was awesome. It was super challenging and he was attentive which made me work my hardest! Now I’m super sore today in all the right places. Highly recommended!

Brian’s beyond rude - what is wrong with this guy? Flatiron is like the flagship store for SLT, and shouldn’t have someone like him to ruin the brand image. I love SLT and all the instructors are super nice, but please get this guy Brian out of the reception desk / picking up any phone calls, he is just so rude 👎🏿

BE AWARE VERY RUDE customer service - Brian at the Receiption picked up my phone call. It’s my first time calling SLT, and just to let them know I won’t be able to make it for the next class in 30 minutes - @3:30pm, I was calling to ask if he could kindly mark my attendance so classpass won’t charge me a cancellation fee, and SLT will still get paid. Inside of telling me yes or no, he said very impatiently “Okay I will TRY, BYE and HAVE A NICE DAY.”

Beautiful gym with great staff and really good equipment.

A great workout! The teachers are awesome and really know what theyre doing.

I am SO sore after working out, I can barely walk. Abs feel hard. I love this place

Addicted to this workout! Hard and very challenging.
