Sammy is the best trainer around. He is responsible for my sons complete transformation as an athlete. Took a slow, skinny kid and turned him into a fast much stronger kid in 12 months. My kids both love working out with Sammy. He takes a personal interest in them and makes it fun. I can’t imagine a better trainer in Jacksonville to develop speed and power than him.

As a father of four high-performing athletes in football and basketball at the high school and collegiate levels, I’ve seen firsthand how Sammy Murray at Top Tier Fitness 904 transforms athletes. He doesn’t just build strength—he trains the whole athlete, developing both the mindset and skillset needed to excel.

Sammy’s focus on total-body training sets him apart. He goes beyond strength and speed, emphasizing mobility, flexibility, injury prevention, and functional power to ensure his athletes are balanced, explosive, and durable. More importantly, he bridges the gap between training and real-game performance, building confidence, discipline, and execution under pressure.

If you’re looking for elite-level training that produces real results, Sammy Murray is the coach you need. He trains the body and the being, making Top Tier Fitness 904 truly top-tier.

Highly recommend!

Great place for ALL. Elementary middle school HS and college athletes to gain explosive flexible strength. This is what college coaches and recruiters are looking for. Sam and his team will get you RIGHT! My son loves the atmosphere and coaching. When my son’s season ended this year in November to now his strength has greatly increased and his body has changed shape. Sam is now getting him ready for college ball. OL have to be large but it has to be in the right places and explosive flexible strength is way to go in any sport. Sam and his team do a great job in a safe environment for all ages. Try this gym out very convenient in St Johns County off US 1. Thank you Sam for helping Zach acheive his goals!
