Strength, Speed, & Agility Coach
Jill Duran
Coach Jill brings over 20 years of fitness experience and a passion for developing young athletes at Strength & Performance Institute. Through the Strength, Speed & Agility program, she helps athletes build speed, power, coordination, and confidence while developing the discipline and mindset needed to continually improve. Her coaching philosophy blends hard work, positive leadership, and a training environment where athletes are challenged, but still have fun.
Additionally, over the last decade Jill has become an active volunteer in the adaptive athlete community through her husband, a former Army Ranger who is now a disabled veteran who competes in handcycling races despite injuries sustained serving in combat. Seeing the resilience and determination of adaptive athletes firsthand has strongly influenced her coaching philosophy. She encourages the athletes she trains to develop gratitude, discipline, and a strong work ethic, reminding them that their greatest limitations often stem from the ones they place on themselves.
