Cyclebar is amazing! It's the perfect combination of Soul Cycle and Flywheel but at a fraction of the prices. Similar to Flywheel, your metrics a tracked throughout the ride, and you can see your progress as you peddle. After the class, you can use the website to see your progress over time. Each workout is intense and I've definitely been able to see proof of how much better I've gotten since I first started a year ago!
All the instructors are great, but they each have their own unique style so you may have to try a few to find the best fit for you. The other thing I love is that there are so many free amenities: free shoes, towels, hair ties, and water. The best part is the chilled towel at the end of each workout!
