Vigilante Fitness Couple are doing their first Spartan Ultra Beast in August. Aside from regular consistent training, we decided that it was a good idea to do an ultra beast simulation to expose us to the long time exertion, fatigue and muscle stress that will hit during the experience. In our simulation, we went through evenly split 10 miles of running, 20000 stairs, 300 Burpees and Hanging Core Exercises.
Most training videos are glorified, but this one is all honest opinion.
