Yasminda Serrano coach at Contender CrossFit

CrossFit Trainer

Yasminda Serrano

Yasminda has always had a love for movement and was intrigued by exercise & the human body; however growing up she had limited guidance in this area. Throughout her life she played in different areas of dance such as High School Pep Squad & Dance Team, Folklorico Dancing and Middle Eastern Dancing.

She loved dance but was guided down a more conventional route of pursuing her degree in Finance and working in Corporate America for nearly 2 decades. Living a mainly sedentary lifestyle while eating the Standard American Diet and working on a computer for 8+ hours a day was really impacting her health causing excessive weight gain, low energy, lack of confidence and much more. Looking to just lose some weight Yasminda joined Contender CrossFit with the guidance from a Coach & Mentor. Unbeknownst to her this moment would change the rest of her life, not only physically but mentally and emotionally. “Prior to coming to Contender I worked out at a gym, did some dance classes, boot camp and kickboxing stuff but never really knew much about weight training. At Contender, I found this community like no other who helped me discover depths of myself (both in the physical & mental aspect) that I never thought were possible. This stuff is life changing and I knew I needed to dedicate my life giving back to others the life that I was given back, so I took a chance & made a career change. I love people and truly want to see others excel and live a life of fulfillment; taking control of one’s health is a major part of that and I am ever so grateful when someone lets me be a part of that. ” Certifications: CrossFit L1 Precision Nutrition L1 Birthfit Coach OPEX CCP L1 CHEK Holistic Lifestyle Coach L1 CHEK Holistic Health & Performance for Women

Sebastian Banda

From his earliest memories, Coach Bash has been in constant motion, declaring humorously that he "came out of the womb running." Growing up in south Texas, he excelled in a variety of sports, including swimming, track, football, and basketball, each contributing to his passion for physical fitness and athletic development.

Today, as a CrossFit Level 2 Trainer, Coach Bash is not just dedicated to his own fitness but is profoundly committed to inspiring and guiding others. He coaches with a fundamental belief in helping individuals achieve their personal best, especially those eager to improve themselves.

Coach Bash loves to help others, especially those that want to better themselves! His approach is rooted in empathy and encouragement, believing that the first step through the gym door is the toughest. His advice to newcomers is straightforward and supportive: “The hardest part is walking through the doors. Once you’re in, you’ll never want to leave! Trust the process!”

Outside the gym, Coach Bash has his most cherished moments spent with his son and wife, Coach Celestial Banda, whether they’re exploring new activities or simply enjoying each other’s company. Not to forget, he’s also a food lover, always ready to indulge in a good meal & has two American Bullies – Tank & Mia!
