Science-backed interval training on echo bikes. A supportive community that keeps you coming back. Real improvements to your cardiorespiratory fitness in just 8 weeks.
✓ Fun, energetic workouts • ✓ Supportive community • ✓ Real results in 8 weeks
We test your Maximum Aerobic Speed — the point where your body shifts from aerobic to anaerobic metabolism. This single metric powers your entire program.
Every workout uses your MAS as the baseline. Sprint zones, endurance targets, and recovery breaks are all calibrated to YOUR fitness level — not a generic template.
Air-resistance, full-body engagement, and self-limiting effort. You can't fake the Echo. It forces honest output—no momentum, no cheating.
Hard efforts are 1–2 times per week. Recovery matters. You'll build aerobic capacity AND sprint power without burning out.
Each series targets a different adaptation. As you progress through 8 weeks, intensity and volume build strategically—all calibrated to your Maximum Aerobic Speed (MAS).
Our 8-week program cycles through 5 different interval series. Week 1–3 builds foundation and technique. Week 4–6 increases intensity. Week 7–8 peak performance with measurable improvements.
You'll track every session—distance covered, watts generated, recovery metrics. Before and after testing shows your exact progress in cardiorespiratory fitness.
