I went to the F45 W 42nd Street location for a Saturday morning workout and it was also their 1 year anniversary party! It was so tough but such a great experience, my Apple Watch says I burned almost 400 calories in an hour workout. I booked through ClassPass but they have good deals for new members too. It's a HIIT style workout with exercises that emphasize both cardio and strength. I did the Spartan workout which had 12 stations that you rotate through three times, then a 15 minute cardio segment (ski erg, bike, row machine). Because you are constantly moving, your heart rate is elevated throughout. The exercises varied from curls to row machine to squats. Such a good workout! For the anniversary party you could spin the wheel for giveaways and they had some free water bottles and baked goods. Love when fitness studios have little treats like that.
