Can I purchase outside of the United States?
We accept all major credit cards whether you are in the US or outside the US. Sometimes, the card has restrictions and will be declined if the transaction is out of ordinary or suspicious. You need to call your credit card company to have the restrictions removed and and try to purchase again.
Can anyone participate?
Yes and No. This program is designed for CrossFit coaches, trainers, and athletes of all levels. No prior experience with endurance coaching and training is required to participate. However, you do need to be in good health and should always seek clearance with a doctor before starting any exercise activity.
Credit card declined
Declines can happen for a variety of reasons. When a charge is submitted to the customer’s bank, they have automated systems that determine whether or not to accept the charge. These systems take various signals into account, such as your customer’s spending habits, account balance, and card information like the expiration date and CVC.
Since these signals are constantly changing, a previously successful card might be declined in the future. Even if all of the card information is correct, and you previously had a successful payment, a future charge can still be declined by a bank’s overzealous fraud systems.
Credit card error
Most often when we see Credit Card errors it is a result of one of two things.
Our merchant service provider recommends the following:
“If all of the card information seems correct, it is best to have the customer contact his or her bank, inquire for more information, and ask for future charges to be accepted.”

If our system fails again, it will automatically retry after 3 days. After 3 failed attempts, your account will be closed due to failed payment.

Will Chris share his Games athlete programming methodology?
Chris uses the same assessment and programming method for every athlete he coaches. It should be regarded that while Chris has had enormous success with CrossFit Games athletes, he has had the same success with other athlete types throughout his 30+ years of experience.
Will my workouts be personalized?
All workouts in our system will be personalized based on your latest performance testing data. This is why we built the training system - To bring his meticulously crafted methodology to the masses.
Will your Aerobic Capacity programming reduce my overall strength?
None of the elite or recreational athletes have experienced any reduction in their max lifts. In fact, every athlete has continued to set new personal records. In many cases, those PR's occur on the same day a workout is performed. As an example, Camille recently set a 200 lb snatch PR on the same day she ran 6800m on the track. Camille is in her 3rd year of programming. Matt Fraser recently ran 3x(3x600m) with 40-second rest between reps and 4 minutes between round; 3 hours later he hit a personal record with his clean at 375lbs. Another example, Rich Froning set PR's in his vertical jump, shoulder press, back squat, deadlift and clean during his first 16 weeks of programming.
