15 seconds on/off x 10
This is becoming one of my favorite workouts. Knowing that the effort a few days ago resulted in a best of 2018 5 minute power average, I went after these. I upped the best to 407. The 15 seconds on went from 516 to 570. I could see doing multiple sets on these. Great way to get big power over 5 minutes without just going at it non-stop.
