Does CrossFit really work?

CrossFit is proven to boost endurance, as confirmed by researchers at the University of Wisconsin, and many claim that it does produce positive results. It is effective in improving endurance and yielding physical changes in part because it combines strength training with cardiovascular exercises. This makes it a full body, comprehensive workout.

CrossFit claims to target the most significant aspects of physical fitness, namely stamina, flexibility, power, speed and more. It requires workouts on 3-5 days per week, and mandates that the workouts are short but of high intensity. The exercises are performed in a circuit, meaning one type of exercise follows the next one.

In terms of equipment, Crossfit usually requires kettle bells, jump ropes and even rowing machines.
