Post each time to comments.

Scaling:
Today’s intervals are all-out sprints on the bike with a twist — you will stand as you pedal. Expect this to add some spice to the workout. Use any stationary bike you have available (e.g., Echo bike, Assault bike, airdyne bike). Each round should be maximal effort. This means each set should occupy every ounce of your capacity, both mental and physical. As long as you are pushing these physical and psychological tolerances then you are hitting this workout as intended. Following each set, rest 2 minutes before the next attempt.

Intermediate option:
Same as Rx’d

Beginner option:
5 rounds each for time:
600/750-meter standing bike
*Rest 2 minutes between efforts.
