CrossFit is high impact on your body, but low impact on the environment. Workouts are intense and combine weight lifting, cardio, core training and more. CrossFit coach Stephen Sylvester gave us more details about CrossFit workouts and coaching methods. Workouts "employ the use of constant variance, meaning that they're intended to keep your body guessing," he said. Variance allows your body to adapt quickly, but there's much more that goes into CrossFit programming. Sylvester told us how coaches must account for a number of details such as time restraints, injury and overuse prevention and movement progressions.

How are CrossFit gyms green?

CrossFit facilities – or "boxes" – are typically located in garages or warehouses and don't require much energy to function. In a box, you won't see rows of cardio machines plugged into a power source either.  Sylvester explained that common CrossFit machines with a display – such as the Concept 2 rower and Assault AirBike – have a battery that recharges it while the machine is used. CrossFit uses other non-electric equipment such as barbells, weights, jump ropes and medicine balls. Also, boxes typically don't have air conditioning or excess lighting. Some rely on garage doors to bring in fresh air and natural light.

In addition, CrossFit "takes a holistic approach to fitness." Coaches address areas such as strength, endurance, accuracy and coordination. Also, they stress the importance of fueling your body and maintaining a healthy lifestyle outside of the gym. If you want to meet your ultimate fitness goals, coaches recommend avoiding sugar and high-glycemic carbohydrates such as bread, candy and soda. The official CrossFit site suggests eating meals that consist of meat, veggies, fruits and nuts – all of which are items you can shop for locally!

How to prepare for a CrossFit class

If you're new to CrossFit, don't be intimidated! Community is a huge key to the CrossFit philosophy – so expect constant communication and encouragement during workouts. Before you step into the action, go to a series of introduction classes to get the hang of different movements and techniques. Most CrossFit facilities make this mandatory for newcomers so they can learn about movements, how to progress and how to do so safely. Sylvester says attending these classes is "one of the most important things you can do to get the most out of your CrossFit experience and avoid injury."
