Bike Version 
5-4-3-2 Rounds // 4 Minutes Rest Between
90 Seconds ON
30 Seconds OFF

**All intervals should be FAST (uncomfortable but sustainable)

Goal: Cover same amount of CALORIES for EVERY 90 second interval. Find what you can maintain without it ever being easy or impossible.

This was done on the AirDyne at some Y up by Lindsay's house. I found it was easier to accumulate calories on the AirDyne. On the assault bike, this would be closer to a 20 or 21 calorie average.
