CrossFit is a fitness program that allows one to select different workouts of the day. These workouts are highly-intense and typically target all muscle groups for a complete body workout. Due to the demanding nature of a CrossFit workout, it is not recommended for beginners but more for those at an advanced level of fitness.
While standard weight lifting equipment can be used during a CrossFit workout, one may often find themselves doing more explosive and fast-firing exercises utilizing ropes, tires, jump boxes, and other ways to leverage one's own bodyweight as resistance.
Nutrition also plays a key factor in CrossFit as the calories expended during workouts is often very high and must be replenished with the right types of food such as quality proteins and low carbohydrate food sources.
