I help athletes increase speed & explosive strength. Hey, I am Justin Laboy, a S&C Coach who helps athletes run faster and jump higher. I have helped athletes run 10.4s in the 100m (electronic), 4.2s in the 40yd, and I’ve trained multiple Division 1 soccer, basketball, and track athletes. I have trained over 1,500 athletes between 2018 to 2024, and my goal is to help you transform your speed and explosiveness! justjumari.com/the-speed-academy/
