CrossFit

CrossFit

Four River CrossFit workouts are comprised of constantly varied functional movements (like pushing, pulling, squatting, lifting, running) executed at high intensity. At 4RCF, you will find kettlebells, barbells, medicine balls, and open space for running, jumping, climbing, lifting, and throwing. The workouts themselves are completely scalable, which means that a new participant and a CrossFit veteran can complete the same workout with changes in load and intensity.

Questions? We (probably) have the answers!

Do you provide free refreshments there?

We have filtered water available to our members. Other snacks and drinks are available for purchase.

Do I have to be fit to join?

No! No matter what your current fitness level is, we have the fitness program that is right for you. Every workout is designed to help you succeed, improve fitness, and move you toward your goals. Our program is designed for universal scalability, making it the perfect application for any committed individual regardless of experience.

What payment methods do you accept?

We take all major credit cards and debit cards. We do not accept personal checks.

What kind of exercises can I expect during a workout?

Our class programming will include a strength portion in which you’ll work on something like Olympic weightlifting, deadlifting, squatting, or bodyweight strength or you may work on a skill like handstand push-ups. After the strength or skill portion of the class is complete, most days will involve a workout that was programmed for that specific day. Workouts can be anywhere between 5 to 20 minutes or more.

Do I have to stop eating my favorite foods to be healthy?

No! A healthy lifestyle has to be manageable and realistic for the long term. Do enjoy special indulgences and meals! The healthier you are, the healthier you tend to want to eat. You get hooked on feeling good, and junk food just isn’t worth it. By avoiding excessive amounts of refined carbohydrates and measuring your intake of protein, carbohydrates, and fat, you will see dramatic, measurable increases in health.
