About Coach

Mariel found GSC through the very first Best Self Nutrition Challenge in 2018. As a competitive high school and collegiate athlete, she was looking for a team-oriented, versatile, and structured community that also offered nutrition guidance. As a member, GSC taught her that wellness encompasses so much more than physical fitness and it is just as important to take care of your nutrition and mental health as it is to learn athletic skills. ㅤ ㅤ ㅤ ㅤ ㅤ ㅤ ‎Throughout her fitness journey, Mariel found a passion for Olympic Weightlifting and competed in her first USAW meet in 2021. In 2022 she placed second in her category at the Florida State Championships, followed by a first-place finish in 2023. Placing a high value on both inner and physical strength, Mariel encourages other women at GSC to participate fully in strength training and enjoys helping others achieve what they never thought possible. She coaches the weightlifting program at GSC and works with athletes to build skills to compete in USAW meets. ㅤ ㅤ ㅤ ㅤ ㅤ ㅤ A teacher for over a decade, Mariel has a passion for helping to bring out the best in individuals through encouragement and accountability. She understands from first-hand experience the vulnerability of starting something new and challenging and is eager to make other members feel comfortable, confident, and in control of their choices as they work to create change in their daily lives.
