Gagan came up through Vidarbha's age-group system, selected for the U-19 side and stepping up to the U-23 squad. Years inside a professional dressing room taught him what daily load, travel and match pressure actually do to an athlete's body — knowledge no textbook hands you.

When playing ended, he crossed the rope. As strength and conditioning coach with Vidarbha's age-group teams he built speed, strength and durability for the next generation of players — applying to their careers everything he had learned the hard way in his own.

Today he coaches independently under Strength Impulse, one of the first three CPSS-certified sport scientists in India. Every athlete he trains runs on a daily monitoring system: wellness, heart rate, workload, recovery — every plan earned by the numbers, nothing left to guesswork.
