Here is a different kind of Instagram channel - instead of being the personal account of a single girl, this account is being run by 2 California-based girls Katrina and Karena. Karena is a triathlete and a model, while Karena is a health science student, which means the two of them are great at supplementing and helping each other out - one with the exercises, and the other with proper diet advice.
According to a recent interview, the duo said that having balance in your diet and exercise is the key to having good health. They told the interviewer, "Balance. Never go to one extreme or the other. Finding a balance in all areas of your life from fitness, diet, work, friends, family, and solo time. A balance in all these areas are all important to living a healthy and happy life."
