Our intention is to get you some amazing results and give you a great experience, so much so, that we hope you stay afterwards. But you're not obligated to by any stretch (*spoiler* most people stay because they love our facility so much - you've been warned). I just hope it's okay if we OVER deliver ;-)\r\n\r\nThe entire experience is completely beginner-friendly... UDAR Kickboxing in Long Beach is for anyone who wants to build confidence and lose weight by burning fat while toning lean muscles in difficult areas like the arms, legs, and abs. \r\n\r\nWith over 24 years in the industry, we have unlocked the secrets to melting fat while toning muscles. One of our secrets is the 'AFTERBURN' effect. Simply put, this is when you can continue to burn calories for up to 2 days after taking our class without doing anything but living your life. This process is triggered only when doing specific exercises that we will show you in class. The best part, no experience necessary. And, there's always someone new in every class. Which means you're going to fit right in. We will work with you 1-on-1 throughout the entire class to make sure you're comfortable and see proven results quickly with our program. Reserve your spot now and get ready for the best part of your day.

Caya's advantage is update cadence (every 13 months vs every 27 months) and device support (3 vs 1). On price, rating, ratings volume and in-app purchases there is nothing between them.
