Active 2 Square December 2025 Software Updates

Active 2 Square
The December update introduces BioCharge and support for TrainingPeaks and Intervals.icu training plans, along with new workout types and Stryd compatibility.
Monitor your all-day training readiness with BioCharge™ to ensure your body is prepared for the challenge ahead. Plus, with the new third-party integrations, you can access a richer variety of structured workouts to elevate your training.

BioCharge
BioCharge represents a whole new way to understand your physical readiness. By synthesizing a complex array of critical metrics—including your nightly sleep quality, daytime rest and naps, Heart Rate Variability (HRV), Resting Heart Rate, and daily activity levels—BioCharge calculates a real-time Energy Score.
Instead of guessing how you feel, this system quantifies the dynamic fluctuations of your body's energy throughout the day. It provides a visual representation of your current state, empowering you to scientifically balance high-intensity training with necessary recovery.
More Variety, More Fun
Keeping your fitness journey exciting is just as important as the hard work. This month, we’re bringing you more ways to engage with your fitness.
Dive into structured training with new support for third-party plans from TrainingPeaks and Intervals.icu. Looking for a new kind of thrill? Try out the new Indoor Rock Climbing activity profile. And for data-driven runners, we’ve added support for Stryd accessories to give you that extra edge in precision training. It’s all about adding more flavor to your workouts.
