Personalized Coaching with Health Data
C4 taps into Health Connect and your wearable to tailor coaching to real metrics. Training intensity, recovery windows, and nutrition guidance can reflect your sleep and activity patterns, making sessions feel balanced rather than random. A typical week might include a gentle day after low sleep, followed by a higher-intensity block when recovery looks strong, helping you stay consistent without overtraining.
1-2-1 Coaching with Chris J. Gregory
In C4, this feature centers on direct, 1-2-1 support from Coach Chris J. Gregory for steady accountability. Check-ins focus on how workouts felt, what changed in daily routine, and where nutrition or sleep needs adjustment. Over time, the plan adapts to your progress, so goals remain realistic and the effort feels productive rather than rushed.
