The circuit training program is designed in a guided format based on sets, reps, and progressive overload. This will allow you to fine tune your workouts and maximize your results over time. We recommend this program if you're looking to learn a style of training that's effective and more in-line with how we personally train to reach our goals. The follow along program is designed to be more in line with how you train with our YouTube workouts. While circuit training can be more effective, we always recommend committing to a program that will give you the best chance at being consistent. The follow along program is built for consistency, effectiveness, and fun with the motivation built into each workout. With this challenge, you will be joining a community of people who will be following along with us and take advantage helpful resources that come with it. We encourage you to utilize the community feed within the app for motivation, encouragement and helpful tips from others doing this challenge right along with you.
