Introducing CrossFit 858

CrossFit 858 will provide fun, top notch, community based fitness training and will help you meet YOUR individual goals. (Not your “Globo gym” or “Big Box” trainer’s goals) Whether it’s to lose weight or put on muscle, when overall fitness comes first all else will follow.

All workouts can be performed “as prescribed” or scaled to your individual capacity. Whether you are an elite athlete or a couch potato trying to get back in shape, all levels of fitness are not only accepted but encouraged. You do not have to “be in shape first” to try CrossFit.

CrossFit 858 has nearly 4,000 square feet of functional space providing functional fitness to the San Diego community. Conveniently located in the middle of Miramar Rd (just East of the Pyramid), CrossFit 858 will be serving residents in UTC, Mira Mesa, and Miramar along with commuters to UTC from Rancho Bernardo, Mission Valley and surrounding areas.

Come in today and see what you’ve been missing out on….

Our community is waiting for you.

XENDURANCE Now Available!


CrossFit 858 is now a supplier of EXTREME Xendurance.

What is Extreme Xendurance?

From their website:

Extreme Endurance is a revolutionary athletic performance formula created by athletes for athletes. This formula has a published, Gold-Standard, third party, double-blind, placebo-controlled, crossover study backing up claims of 15% reduction in lactic acid and a double digit increase in aerobic threshold. Many companies make claims on individual ingredients but Extreme Endurance has a published study on the formula itself. Each batch of Extreme Endurance is tested to ensure that it is not contaminated with banned substances to provide additional reassurance for elite athletes.

Extreme Endurance Advantages:

  • Clinically Proven to Reduce Lactic Acid by 15%
  • Speeds Recovery
  • Improve Aerobic Threshold by Double Digits
  • Benefits Within 72 Hours
  • Reduces Muscle Soreness
  • Certified Drug-Free

My experience:

I can tell you that I will never carry a product that I don’t use myself.  The Xendurance rep actually came by 2 months ago, and I’ve been on the product since then.

I went through the 2015 Open on this product and I honestly have felt no muscle burn or lactic build up.  I especially noticed this was the case after multiple (stupid) attempts at 15.3 (WallBall, Muscle Up, Double Unders) and felt zero soreness after 15.5 (Row Thruster).  My chest felt like I was stomped on by an elephant, but that was due to 15.5 :)

I am still on this product and intend on keeping it on board.  I feel better during the workouts and feel it helps with recovery.
