Nic Martinez, PhD is a Professor of Kinesiology, performance scientist, and published author of research whose primary career focus is the optimization of human performance. He is a certified exercise physiologist who has worked as a performance coach with professional, Olympic, and collegiate athletes, and a certified health coach who emphasizes the dimensions of wellness. 

Across hundreds of training plans, recovery protocols, and observations, Nic kept arriving at the same conclusion. The athletes, clients, and coaches he worked with covered nearly every pillar of performance, from programming and nutrition to recovery, yet their circadian biology was almost never on the table. Sleep was managed. Session timing was scheduled around logistics. Meal plans were precise. However, the underlying rhythm of the athlete, including chronotype, personal peakof strength, cognition, and reaction time, and the windows where their physiology was built to perform, were treated as background noise rather than a primary lever.

Chrono Zones was born to close that gap. It is a mobile app that places circadian biology alongside training, nutrition, and recovery as a foundational pillar of human performance. Chrono Zones translates chronotype science into a practical performance layer. It maps an individual's natural rhythm, reveals their peak windows, and aligns training, fueling, and rest with the body's own clock. For elite athletes and everyday fitness enthusiasts alike, the goal is the same. Stop fighting the clock and start training with it!
