I beat a friend's Challenge but our scores are reset. What gives?

It’s easy to get caught up forever perfecting a single routine and setting a high score. Our leaderboards track all-time best score. Live Challenges are all about what you can do TODAY. We’ve set them up to reset periodically every 1-2 weeks so your Live Challenges feed will always display what your friends are doing now, not what they did on some Tuesday last March.
