I first started Crossfit as a way to help me learn to turn on and off my muscles faster. As an endurance athlete I can go steady for quite some time and in the various disciplines of triathlon without too much fatigue but ask me to sprint and I was toast. After watching some classes on Crossfit I decided to try it out. My intention of doing crossfit was not to try and lift the most but work on my weakness which was speed. All of the Olympic lifting moves that you learn in Crossfit require an enormous amount of speed and strength in order to execute them properly so my challenge began!
Not only did I have to learn to move quickly and learn the required techniques, almost all of the movements in the Crossfit workouts required my body to move in ways it was not used to like doing box jump burpees, double unders, wall balls, pull ups of any sort, gymnastic moves on the rings and on the floor, and the Olympic lifting.
For my last ironman I added in Crossfit training days and loved it. After doing some heavier lifting moves we would then move into running sprints, box jumps and pushups. I loved how I would have to perform all of these moves within a certain time or against others for a time while my body was tired and wanting to give up. I liked the competition of having others around to push me and I liked the mental challenge of digging deep to finish off the workout. I would also combine my Crossfit workouts with either a swim, bike or run either pre or post workout which I would classify as one of my brick workouts. There is something called Crossfit Endurance, by Brian MacKenzie, which combines endurance sports training with the speed and power of lifting moves, and is worth checking out.
If you have been an endurance athlete for some time and are looking for something that might help you reach your next goal and improve your overall athletic performance I would check out Crossfit and see what you think.
