Preworkout supplements have existed for years, but have been engineered for bodybuilding and powerlifting. These are great, but endurance athletes don't need such extreme levels of caffeine and preworkout jitters before their workouts, especially when trying to manage heart rate during zone 2 base building! Hence, Zone 2 Starting Block was created to provide a preworkout spark with everything runners need, without the extremes.

Definitely not! Starting block will provide sustained energy and focus for all kinds of activities. Take it before your gym workout, dance class, jiu-jitsu class, or any other activity where you want jitter-free energy to power you through. You can also take it before the big test at school or important work meeting for extra focus.
