How we measure real cardiovascular fitness progress
As you get fitter, you face a frustrating reality: BEAT Points reward reaching high heart rate zones. But here's the problem—as your cardiovascular fitness improves, it becomes harder to reach those zones. Your heart becomes more efficient (which is exactly what you want!), but the BEAT Points system inadvertently penalises you for it.
You're genuinely improving—recovering faster, maintaining lower heart rates for the same effort, finding workouts easier—yet your BEAT Points plateau or even drop. It's demotivating.
Rhythm Score solves this. It measures what actually indicates fitness improvement: better recovery, improved heart rate efficiency, easier perceived effort, and consistent training. Unlike BEAT Points, Rhythm Score increases as you genuinely get fitter.
Rhythm Score is calculated from four weighted components that capture different aspects of cardiovascular fitness:
Your recovery points trend—the single most important fitness indicator. Higher recovery = better cardiovascular fitness.
Lower heart rate percentage for similar effort = better cardiovascular fitness.
How hard workouts feel—captures both physical and mental adaptation.
Rewards adherence to your personal training rhythm, whether that's 1x/week or 7x/week.
Rhythm Score uses absolute scoring—it rewards having good fitness metrics rather than just improving from your personal baseline. This means:
✓ Fit users score higher than unfit users from day one
✓ Elite users can reach 90+ scores
✓ Progress is clearly visible as metrics improve
✓ Scores are comparable between users
Recovery: 42 points → (42/40) × 100 = 105 × 0.40 = 42 points
HR Efficiency: 92% → 150 - ((92-85) × 5) = 115 × 0.25 = 28.75 points
RPE Efficiency: 4 → 150 - ((4-3) × 14) = 136 × 0.20 = 27.2 points
Consistency: 3 sessions/week → 75 × 0.15 = 11.25 points
Raw Total: 42 + 28.75 + 27.2 + 11.25 = 109.2
Normalized Score (0-100): max(0, min(100, 109 - 50)) = 59
Starting your journey or returning after a break. Your body is adapting to regular training. Focus on consistency and building a foundation.
Solid baseline fitness. Training regularly keeps you at this level. You're consistent but not pushing progressive overload.
Clear improvements visible. Recovery getting better, HR dropping, workouts feeling easier. This is where most dedicated members sit.
Elite territory. Consistent 3-4x/week training with excellent recovery and HR efficiency. You're in the top tier of fitness.
Exceptional cardiovascular fitness. Very high recovery (45-50), HR in the 82-88% range, workouts feel easy. This level requires dedicated, consistent training.
Baseline: 37 rhythm score (recovery: 28, HR: 96%, RPE: 5, sessions: 3/wk)
After 12 weeks: 58 rhythm score (recovery: 40, HR: 90%, RPE: 4, sessions: 3.5/wk)
+57% improvement—clear fitness gains!
Month 1: 9 rhythm score (recovery: 18, HR: 97%, RPE: 8, sessions: 1/wk)
Month 5: 39 rhythm score (recovery: 35, HR: 95%, RPE: 6, sessions: 1/wk)
+333% improvement—sustainable rhythm with real gains!
Baseline: 35 rhythm score (recovery: 26, HR: 97%, RPE: 7, sessions: 3/wk)
After 12 weeks: 68 rhythm score (recovery: 39, HR: 91%, RPE: 4.5, sessions: 4/wk)
+94% improvement—exceptional progress with optimal training!
Peak recovery (46), excellent HR efficiency (84%), low RPE (3), perfect consistency
Rhythm score: 94-95 (near ceiling)
Top 1% of fitness—hard to improve further!
The score still works 80% effectively! When RPE is missing, the weights shift: Recovery (50%), HR Efficiency (30%), Consistency (20%). You'll still see meaningful progress tracking.
Rhythm Score uses absolute scoring, not relative. If your friend has better recovery, lower HR%, and trains more consistently, they'll have a higher score. This is by design—it rewards actual fitness, not just personal improvement.
Rhythm Score uses your most recent sessions (typically last 8-10 sessions) to calculate current fitness. You'll see changes within 1-2 weeks of consistent training.
Not really. To artificially inflate your score, you'd need to simultaneously: improve your recovery points, lower your HR%, train consistently, and reduce perceived effort. The only way to do this is... to actually get fitter. The system is designed to resist gaming.
BEAT Points measure how hard you worked in a single session (time in high HR zones). Rhythm Score measures your cardiovascular fitness over time. Think of it this way: BEAT Points = effort in that workout. Rhythm Score = how fit you are overall.
Absolutely! Rhythm Score celebrates any consistent training pattern. If 1x/week is sustainable for you, and you stick with it, you'll see real improvements in recovery and HR efficiency. The algorithm rewards long-term adherence (2 years of 1x/week) just as much as sporadic higher frequency. Your score will reflect your genuine fitness gains, not penalise you for a sustainable rhythm.
Rhythm Score solves the fundamental problem with BEAT Points: as you get fitter, your BEAT Points plateau because you can't reach high HR zones as easily. Rhythm Score rewards the real improvements—better recovery, lower heart rate, easier effort—so you can see your true cardiovascular progress.
It's not about gaming a number. It's about understanding whether you're genuinely improving, and celebrating the hard work that goes into getting fitter.
