Megathon 

A challenging series of workouts led by Beachbody super trainer Megan Davies that consists of 2 live streaming workouts a day; spanning 3-4 days in a row.
These workouts occur once a month on the Beachbody on Demand Interactive workout platform and are designed to increase strength, improve cardio and endurance and burn fat.

Man, I still can’t walk up the stairs after doing the Megathon last week!
