Sure thing. Start with a carbon‑fiber frame, keep the mass down. Use an electromagnetic motor with closed‑loop speed control so the treadmill can instantly react to the runner’s power output. Integrate a load cell in the belt for real‑time force feedback and feed that to an algorithm that adjusts belt tension and resistance on the fly. Add a high‑resolution optical encoder for precise speed measurement. Keep the electronics minimal—just what’s needed for control and telemetry. That should give you a lean, smart, brutal system that actually improves performance.
