 Trustindex verifies that the original source of the review is Google. My grandson attended the FitFirst Ninja Parkour camp. He absolutely loved it and he is very picky about what he loves to do. The course was challenging and fun with fantastic coaches. Coach Marcus and Coach Michelle are fantastic. They are friendly and motivating. Coach Marcus inspired the kids to work harder and harder to improve their skills and he did it with a smile throughout! We will be looking for more opportunities with these coaches!

 Trustindex verifies that the original source of the review is Google. We cannot say enough great things about Fit First Youth Fitness Training! As parents of nationally ranked teen and pre-teen athletes, we knew we needed a trainer who focused + specialized in working with kids -- someone who understands their growing bodies/joints and can develop a program that keeps them strong, motivated, and injury-free. After trying a few trainers, we feel incredibly lucky to have found J at Fit First. Not only do they bring top-tier, experienced trainers to our home (which makes scheduling so much easier), but the level of expertise, patience, and motivation our trainer and the admin team provide is unmatched. Having worked with personal trainers ourselves at high-end gyms like Sports Club (now Equinox), we know what great training looks like -- and this is it! The workouts are engaging, well-structured, and designed to instill healthy physical and mental habits that will benefit our kids now and in the future. We are very happy.

 Trustindex verifies that the original source of the review is Google. My 12 y/o son always wanted to try parkour and never had a chance to. After sustaining an injury from a football game with a displaced fracture on his collarbone, he's out for any sports for months. Fit First Ninja Parkour Camp was the first sports that he tried after the injury- thanks to Vivian, the program coordinator who helped us greatly to enroll my son even after camp already started, and to both Coach Marcus and Coach Michele for providing him such wonderful introduction to this challenging and fun sports. My son had the best time training with them at the camp, and we felt extremely cared, encouraged, inspired and motivated in this program. The night before last day, my son was injured (again!!) from a scooter accident, scraped his knee pretty badly and couldn't participate in the last day of the camp. Coach Michele delivered his awards to our door that almost made me cry! Coaches and management are just amazing and truly caring- they treat their students like family. I am so glad that we found this camp for my son after his major injury and to re-pick up his love in sports. We will definitely continue coming back for more classes and parkour training!
