CrossFit
We offer a variety of programs depending on specific goals as well as experience/fitness levels.
Our CrossFit Program is a general physical preparedness program designed to build strength, endurance and help get you in the best shape of your life. Regardless of your experience or ability level, the CrossFit program focuses on developing a well-rounded athlete. The workout is the same in each general CrossFit class. At busier times, we separate by ability levels to make for more effective coaching and a better learning experience. To sign up for your free introductory CrossFit class or first month of classes, click here.

For those looking to ease their way into CrossFit, we offer a monthly Fundamentals Program 8+ months per year. This program is designed to ramp up your fitness and give you more exposure to the movements involved in CrossFit before general classes.

STRIVE-X is open to all fitness levels – no prior experience necessary!
The objective of STRIVE-X is to build cardiovascular endurance, strength, and body awareness. The workouts are different with each class. The class is structured with intervals varying in length and intensity. We use a large variety of equipment and exercises that will give you a full-body workout every time you visit. If your goal is to burn fat and change your body composition, then this class is for you! All movements are reviewed and warmed up at the beginning of class. Athletes will be grouped and will start at different stations. Athletes choose their own weights and difficulty. STRIVE coaches will be available to assist in scaling the weights, repetitions, and movements to meet the needs of all ability levels.
STRIVE-X programming is constantly varied and always challenging.
STRIVE Strength & Conditioning
STRIVE Strength & Conditioning focuses on a strength portion which includes mostly accessory lifts that are great for all.
The conditioning portion involves rowing, biking, sled pushes, running, skiing, and occasionally body weight movements. This is a great option for anyone who wants to get stronger but does not want to Olympic Lift or do a traditional CrossFit style metcon.
This class can/has also served as a great compliment to our CrossFit program. The accessory work performed helps strengthen smaller muscle groups that assist in generating more power in major lifts, in addition to helping in injury prevention.

Specialty Classes
Specialty Classes are available to help you exceed in your sport and improve your fitness. These classes include Barbell Club | Olympic Weightlifting and Mobility. We also offer One on One Mobility Screening, to asses movement patterns to improve efficiency and prevent injury.
Competitors
Our Extra Work is supplementary work programmed to enable athletes in CrossFit classes to take their fitness to the next level. Extra Work consists of more technical lifts, extra conditioning and advanced gymnastics skills. Extra work helps gain success in the competitive CrossFit arena. A good, solid foundation of general class skills, GPP and CrossFit fitness requirements are encouraged before jumping in full force. Consult with your coaches. Extra Work is listed daily on Sugar WOD and can be found on the whiteboards in the desk space.
