Blending Cardio, Recovery, and Smart Contracts – Any Unique Ideas?

Lately, I’ve been curious about how to mix my love for dance, cardio, and recovery with my interest in smart contracts. Has anyone experimented with tech-driven approaches to fitness tracking or rewards? For example, setting up a smart contract that unlocks a donation to a charity after hitting a weekly step goal or maybe even automating workout challenges with friends. I’d love to hear if others have tried something similar or have creative ways to merge these worlds. How do you keep cardio and recovery engaging while playing with tech?
