Krystal Jackson is a former All-American volleyball player for UCLA where she was a four-year starter and led them to top-five finishes all four years she played.

During her sophomore year she needed a shoulder surgery that took her out of competition for six months. 

This surgery plus the revelation that her father had Type 2 diabetes helped her find her passion for weight training and fitness and was voted "Most Conditioned Athlete" on her team a record three times.  

After college she played on the AVP Professional Beach Volleyball Tour and also represented the USA Volleyball internationally in countries all over the world.

After her playing days were over she became instrumental in building Jackson Strength with her husband Curtis. Jackson Strength is a facility specializing in training athletes of all ages, shapes and sizes. 

Due to their passion for learning and love of lifting, they were able to turn Jackson Strength into a premier facility for athletic performance and injury prevention in the San Diego area. 

She has learned from legends in the strength and conditioning world and holds certifications from NASM, CPPS, RYT and CFSP.

She loves lifting weights, yoga, yummy healthy foods, mentoring youth athletes, and spending time with her family.
