Spartan Boulder WorkoutNew type of “brick” workout. In triathlon a brick workout is when you combine two pieces of the triathlon into a single workout. As I prepare for the Spartan Beast race at the end of the year I’m trying a different type of “brick” workout. The work is simple, pickup a heavy boulder, throw it, pick it up and repeat. The boulder in this video is a piece of concrete trash I found that weighs 37.2 pounds.
