I have three teenagers (13,17 and 19) that work out at Athletic Republic and feel completely comfortable with the safety protocols they have in place. My kids really enjoy the workouts and it helps keep them in shape. I was very glad they were able to reopen in June.

When it came time for my oldest daughter to improve her speed, agility and conditioning for soccer we chose Athletic Republic. Having been a former health club owner I knew this was the facility with the staff to accomplish those goals. That was ten years ago. She trained there throughout high school and college attaining academic All-American honors. Now my youngest daughter is midway through her Division I lacrosse career and is getting similar results. She has improved her speed, agility and conditioning over the last 6 years and will continue to utilize the facility and staff.

Athletic Republic has been instrumental in helping my players and sons become better athletes. The staff is super knowledgeable and does a great job of pushing the athletes to reach their full potential. I refer anyone who asks me how to increase their foot speed,strength, and explosiveness to Athletic Republic.
