TESTIMONIALS
I never thought I’d say this, but I’m excited to wake up at 4 a.m. and see what Mike has planned for us. Though I have a long road ahead, I am confident I'll reach my goals, and I owe a great deal of gratitude to GRIT.
SAMANTHA D. | TABERNACLE, NJ
My advice...if you have a child that is athletic, enroll them in GRIT and they will be better athletes. If you have a child that isn't athletic, enroll them in GRIT and they will be healthier AND more confident.
It is WIN-WIN.
MATT D. | TABERNACLE, NJ
Hands down, one of my best decisions was to start taking classes at GRIT. Mike is an amazing instructor. The gym is clean and the environment is fun to work out in. I can't wait to sign my kids up to help them succeed in their athletic abilities.
BECCA L. | TABERNACLE, NJ
GRIT is a fantastic easy going place to work out. Mike is super knowledgeable and keeps the workouts challenging, but fun. Love the early morning 45 minute classes to get the day going.
MATTHEW D. | MEDFORD, NJ
Great program for the entire family! Coach Mike is supportive and motivating. Highly recommend!
AMY H. | TABERNACLE, NJ
I am so glad I joined GRIT! It is such a positive environment where you truly feel comfortable working out and becoming your best self. Mike is extremely encouraging. The change in workouts makes every class different! Definitely join GRIT if you are thinking about it!!!
SKYLAR D. | TABERNACLE, NJ
This is the perfect gym for age-appropriate cross-training for all sports and fitness levels. My kids (10 and 12) have gained strength, speed, and agility attending the JV kids' classes. The classes are kept on the smaller size which allows Mike to correct form and focus on each athlete. Mike keeps the classes fast-paced and keeps the kids engaged throughout. Recommended for any athlete looking for a cross-training environment.
