ATHLETE SUCCESS STORIES
"I've trained with Terry and GP since middle school. It really helped prepare me for college football and now that I'm in the NFL, it's evident I've trained the correct way because it's the same stuff that I've been doing at GP.
GENO STONE
NFL, Cincinatti Bengals
“My daughter is a junior and a pitcher for fast pitch. She had a goal this, year to hit 60mph and she needed 4-5 mph. Terry and his group of trainers made this possible in 4 months she accomplished her goal. Terry and his group of trainers are amazing. They take the time to get to know each athlete and what their needs and goals are and make it happen. I have 2 other children that go to GP. One is also a 10u pitcher her goal was to get to 50mph pitching, she hit 52. I also have a son who plays all sports and what he’s accomplished speed and agility is just amazing. THANK YOU TO TERRY AND HIS STAFF."
