As a sports nutritionist, there are plenty of things that annoy me when engaging in the health and fitness community online. Right near the top of my list are people that think a keto diet is the solution to improving everyone’s sports performance. Hint: keto is not the answer. Not too far behind, are those that believe that pre-workouts don’t work, and that you shouldn’t take one. Now it’s true, you don’t *need* to take a pre-workout to train or compete. However, it’s absolutely not true that they don’t work. In fact pre-workout supplements can be very useful for many people in different situations.
