"Hello Mr. Amundson. My original background is in martial arts, teaching Taekwondo and Kickboxing. Since I've discovered CrossFit I've never been in better shape in my life. I've never felt better, never been faster, never lifted more, or more importantly to me, never been mentally stronger than I am now. When I began training, simply attempting the WODs was satisfying enough at first. Then setting goals helped keep me motivated (double body weight deadlift, improved Fran, linking muscle-ups). But now I'm consistently motivated to just be a better me thanks to your mental reworkings! I recently watched your lecture on leadership and mental workouts at the CrossFit One facility at Reebok HQ and it was the most eye opening, light bulb moment I've had in CrossFit to date. Equal to any PR! I've literally set free my anxiety over certain WODs or techniques. Your energy and enthusiasm is palpable through the screen and your examples and metaphors are inspiring! I hope you're breathing fire for years more and someday I can thank you in person."

In the summer of 2009, I was fortunate enough to observe Greg Amundson complete a workout at the Navy Base pool in El Centro, CA. The heart and passion Greg put into his workout was obvious and inspiring. He extended an invitation to me to workout at his garage that week and that session ultimately redefined my mindset of what fitness is.

A diverse background in team sports such as football, soccer, basketball and rugby exposed me throughout my life to various methods of working out. I have also had training in Karate specifically Tae Kwan Do, Boxing, Wrestling, and Jiu Jit-Su. I like to skateboard, snowboard, wakeboard and surf as well, when I can. However, nothing has challenged my mind and body quite like CrossFit. With each class I attended at the Amundson’s, I quickly became eager to further my knowledge and within a few months obtained my CrossFit Level I Certificate.

Recently attending the CrossFit Mobility and Recovery Course and the Olympic Lifting Course gave me a taste of what the world of CrossFit has to offer. I look forward to attending the CrossFit Football Course in February, and don’t plan on stopping there!

As a CrossFit athlete, I have seen my fitness level increase drastically. I pour all my energy into every workout and know when I’m finished, that I’m finished! I strive for excellence in each and every workout and carry this mindset into every aspect of my life.

Greg Amundson stated, “CrossFit Affiliate Coaches have an unique ability to change the world. The best way to do this is by setting a positive example for their athletes to follow – both inside and outside the CrossFit box.” As a CrossFit Amundson coach, I intend to share my knowledge and passion for CrossFit. I find it rewarding to help athletes meet goals, surpass feats of strength they thought were unattainable, and break PR’s. I enjoy working with athletes of all abilities and look forward to applying my skills to help them achieve their fitness goals.

Trainer at CrossFit Imperial Valley, CA

I first heard about CrossFit through a friend in early 2010. “You need to do CrossFit, it’s amazing,” he told me. I did some online research and concluded that while the workouts were impressively grueling, they appeared to required good form and correct technique in areas of athletics that I was unfamiliar with. After refusing to go, I started seeing changes in my friend that impressed me. Not only did he get stronger, more fit and loose weight, I could also see that he genuinely enjoyed and looked forward to attending his CrossFit class. He motivated me and I finally gave in and journeyed to the garage where CrossFit Amundson was holding their classes at the time. Immediately I felt welcomed. We stretched as a group, almost like a team. The class was competitive yet friendly, full of high fives, positive vibes, everyone sweating and feeling each others pain. It was something I hadn’t felt in a long time. I was hooked. Being a former collegiate athlete I had never experienced a workout quite as intense as CrossFit. I took the Fundamentals class and I knew that CrossFit was going to change my life. And, indeed, it has and is continuing to do so.

Today, I most enjoy coaching people who don’t yet realize that they are amazing athletes. It is rewarding to bring out the best in people. Something like helping a client complete a partial squat after knee surgery is an amazing accomplishment that is every bit as gratifying for me as it is for them. Once a new athlete walks into the gym, they’ve already made a huge gain in their health and fitness simply by being there willing to try CrossFit. It is then my job to help them become the athlete I know they can be.

PJ Enders was born and raised in Brawley. She has her Associates degree in general studies. She is a CrossFit L1 Trainer, a lifeguard Instructor and a Water Safety Instructor. She played volleyball and softball in High School and at the Junior College level. Her favorite workouts include wall balls and anything heavy!
