Warning: this virtual cycling game is extremely addicting...you've been warned. I've never trained as a cyclist before and I wanted to see how much I could improve after a month using Zwift using their FTP builder training plan. My watt/kg FTP increased by 15% in just 28 days!

Even though not required to run the game, I found having these extra sensors to be helpful for keeping pace in workouts:
