Ursula Valencia is a certified personal trainer & fitness nutrition specialist, a national figure competitor, figure & bikini coach, mother, and wife. She’s been a fitness enthusiast since she was a teenager, always striving for a healthier, stronger body and to help others achieve the same.

Ursula started personal training and competing in 2010 and coaches both competitors and general fitness clients. After many years of face to face training, she developed an online coaching company so she could help more than just a few local clients. In no time the company grew and she needed help to maintain the quality of service and attention to clients she had been providing. She needed to partner with someone who she could trust with her clients’ health and who was just as knowledgeable about nutrition, training, weight loss, competition coaching & posing as she was. Her dear friend Alissa Parker was the obvious choice and FlexRx was formed!
