How to Prepare for the F45 Challenge with the Reebok Smart Ring

The F45 Challenge™ is a 45-day guided program built around your specific goal, Power, Lean, or Athlete, with coaching, nutrition guidance, and workouts tailored to what you’re chasing. But showing up for class is only half the equation. What happens in the other 23 hours, your sleep, your stress, your recovery, determines how much you actually get out of those 45 days. That’s where the Reebok Smart Ring comes in.

What Is the F45 Challenge?

Challenge is built around three goal-specific tracks, all training together in the same class:

• Power track — for members who want to build muscle and get noticeably stronger, with progressive overload and lift tracking each week.
• Lean track— for members focused on reducing body fat, preserving muscle, and building sustainable habits, with workouts designed to keep heart rate elevated.
• Athlete/Performance track— for members chasing speed, power, and conditioning, with explosive sessions and performance data to track.

Whichever track you choose, your progress is measured with InBody scans at the start and finish, plus weekly coaching and nutrition content along the way. That’s a lot of data about where you’re starting and where you’re headed, but it’s only half the picture. The other half is what the Reebok Smart Ring tracks every day in between.

The One Score: Your Daily Readiness Signal

At the center of the Reebok Smart Ring is the One Score, a single number from 0 to 100 that distills your steps, movement, stress, sleep, and recovery into one daily readiness figure. Instead of parsing a dashboard of graphs, you open the Reebok Fitness App and get one clear signal: push, pace, or prioritize rest.

For anyone doing Challenge, that signal matters. Forty-five days of consistent training only pays off if your recovery keeps pace with your effort. The One Score is built on three inputs:

• Activity — every F45 session you log, plus the steps, distance, and calories you rack up outside the studio.
• Stress and recovery — driven largely by heart rate variability, which tells you whether your nervous system has bounced back from your last session or is still working through the load.
• Sleep — tracked across light, deep, and REM phases, since sleep is where the actual adaptation from your training happens.

A dip in your score isn’t a failure, it’s information. It might mean an active recovery day or an earlier night serves you better than another full-intensity circuit. A climbing score is your cue to go all in.

Four Ways to Use the Ring to Prepare for Challenge

1. Let Recovery Data Guide Your Training Load

Forty-five days of F45 programming is demanding by design. The ring’s readiness, resting heart rate, and stress metrics tell you when your body is primed to push and when it’s still catching up. Training hard only works when it’s matched with smart recovery, and overtraining partway through Challenge can undercut the very progress you’re chasing.

2. Use It to Pace Across Your Track

Whether you’re in Power, Lean, or Athlete, your One Score trends help you see how your body responds week over week, so you can balance strength work, conditioning, and rest days deliberately instead of guessing. That’s especially useful heading into the higher-intensity weeks of your track.

3. Prioritize Sleep From Day One

Challenge asks a lot of your body over 45 days, and sleep is where recovery and results actually compound. Tracking your sleep phases from the start gives you a baseline to build better pre- and post-training routines around, so the gains from each session have a chance to stick.

4. Check In Around Your InBody Scans

Your before and after InBody scans mark the start and finish of Challenge. Use your One Score trends in the days leading up to each scan to make sure you’re walking in recovered rather than depleted, since fatigue and poor sleep can skew how your body composition results actually read.

Train Hard, Recover Smarter

The F45 Challenge gives you the program, the track, and the community. The Reebok Smart Ring gives you the layer in between sessions that tells you how ready you really are to meet it. Stack 45 days of smart training with smart recovery, and the results follow.
