Ok Vince, lets start with sets 15 with olympic lifts like cleans. Lets assume the technique is proper, after multiple sets form begins to break down and eventually causing injuries. Vince give an out line of the routines you use.
Seems crossfit has no rhyme or reason when put the WOD of the day together, everything is random and thrown together. All designed to basically get you to sweat and make you think you're getting a great workout when in reality you're just being broke down. Want me to go on?
First off, the WOD is meant more for people who are already experienced in Crossfit Exercises. And again, Coach, its all up to the trainer to monitor their client to insure that they are using proper form and a proper amount of weight. Most beginners actually start out doing cleans with a PVC pipe and then work their way up. In addition, while Olympic lifts are the popular core of Crossfit, a number of routines can be put together without doing Olympic lifts using box jumps, kettlebells, and even nothing but bodyweight.
The dangers of Crossfit are no different than regular exercise.
