Challenge 51 is almost here and this year, it’s more personal than ever.
F45 Challenge is a guided 45-day program built around your specific goal. Select your track, train alongside the rest of your studio in the same class, and get coaching, nutrition guidance, and workouts tailored to exactly what you’re working toward.
Choose one of three tracks based on your goal, and you’ll receive information tailored to your track:
POWER
Designed for members who want to build muscle and increase strength.
LEAN
Designed for members who want to reduce body fat, preserve muscle, and create sustainable habits.
ATHLETE
Designed for members who want to improve speed, power, and overall performance.
Once the Challenge begins, here’s what your experience will include:
Nutrition guidance: practical tips to support your goals throughout the Challenge
Progress tracking: log measurements and set goals
Educational content: tips and expert guidance to help you train smarter, recover well, and build habits that last beyond the 45 days
The Challenge runs October 5 – November 18, and registration is open now!
