Ashley Rincon

Ashley is a current Law Enforcement Officer and life long athlete who brings a wealth a real world competition and coaching experience to CSA.

Ashley played and coached competitive soccer for the majority of her life and she has an impressive “distance running” competition background having run everything from 5K’s to full Marathons and everything in between. While running, Ashley was introduced to weight lifting. As hesitant as she was at first to start lifting, once she started seeing the results she knew she had found a new passion. After several injuries inhibited her from continuing with soccer and distance running she was introduced to CrossFit at CSA. Ashley soon realized that CrossFit is not just a “workout regimen”, but a life style and she’s been hooked ever since.

As a Police Officer/Tactical Athlete, Ashley has found that CrossFit helps to not only keep her in the shape necessary to preform the duties of her job, but it keeps her coming home safely every night. Since joining our family, Ashley has been a passionate CrossFitter, who quickly became a key member of the CrossFit CSA Competition and has competed at multiple competitions including FemmeFit, the 2010 Weekend Warrior series and the 2011 Rebook CrossFit Games (Norcal Regionals). To continue her journey with CrossFit Ashley has recently completed her CrossFit Level 1 Trainers Certification and now looks forward to coaching and sharing her extensive experience with our CrossFit community/family.

Glenn Pendlay



The “Pendlay” name is synonymous with Olympic Lifting as Glenn Pendlay has been coaching Olympic Weightlifting for over 20 years and CSA is very excited to welcome Mr. Pendlay and his team to the CSA Family.

Glen’s entry into the sport came in 1992 when he had the chance to learn how to do the lifts himself from Russian legend / coach Alexander Medvedyev after attending the Junior World Powerlifting championships in Moscow. Medvedyev invited Glenn to stay and train with him, and taught him the basics of Olympic Weightlifting. This was a life-changing experience.

Glenn had started School at Kansas State University with the intention of graduating with a history degree and becoming a high school teacher. His experiences in Moscow, especially seeing the science aspect of training and human performance, made him change his major immediately upon getting back from Moscow to Exercise Physiology. He eventually graduated from KSU with a BS, and went on to get his Masters degree in the same field.

Glenn chose to do research in the field of endocrinology while completing his Masters degree, specifically studying how different levels of stress affect the endocrine system and how this in turn affects the bodys adaptation to the stress. This research led to multiple papers being published in peer reviewed journals, and also to Glenns’ working with not only weightlifters, but athletes from as diverse of backgrounds as cyclists, skiiers, and track and field athletes.

Wichita Falls Weightlifting was established in 1999 with Glenn as the head coach, and from 1999 to 2009 was one of the top producing clubs in the USA. During his time as the coach of that club, Glenn produced over 90 national champions, over 20 medalists in international competition, and his athletes have broken as many as 10 American records in a single year. He has coached successful athletes all the way from 10 year old Schoolage National Champions, to Senior World Team member and Pan American medalist, to Masters World Champion and World Record holder. His teams also competed successfully for team championships, including 6 mens collegiate national team titles in 7 years, and a string of 3 Junior National team titles in a row!

Glenn is currently one of the primary instructors for the USA Weightlifting Trainer/Coaches certification programs and is also the head coach for the California Strength Weightlifting team, currently coaching a group of athletes which includes American Record holder and #1 ranked American Junior lifter Caleb Ward, and Senior national champion, World Team members and Pan Am team members Donny Shankle and Jon North.

Donny Shankle

A leader in health and fitness, Donny Shankle is a four time national champion and world team member in the sport of weightlifting. He is the only weightlifter in the United States to defeat in competition a defending world champion in over 30 years. At the 2007 annual Arnold classic Donny was named the country’s most inspirational weightlifter. He is the only American weightlifter to have trained both as a resident athlete at this country’s regional Olympic training complex and under the tutelage of the world’s greatest weightlifting coach and teacher’s Ivan Abadjiev and Glenn Pendlay. Donny is a marine corps veteran of the Iraq war and resides in San Ramon, CA.
