"Thank you for creating a place that I can be myself."

"I loved Jenn’s boot camp! She has great energy...even at 5:30 in the morning. I got a thorough full body workout and felt great the rest of the day. Highly highly recommend Jenn’s classes!"

"Jenn is wonderful! She keeps you motivated and comes up with fun, challenging workouts. Can’t wait to take more classes with her!"

"CampEx is intense and so good!"

"If you’re looking to get fit and also enjoy yourself while doing it, I seriously recommend J.Gil’s group fitness classes! I really enjoy the modification options that she gives for each exercise, but she also isn’t afraid to push you to do what she knows you can! I just finished a 6 week class and I feel healthier, stronger, and more eager to continue my fitness journey! I can’t wait to do more! Thanks Jenn for being an amazing trainer!"

"j.gil is the best!"

"This Team has brought so much positivity into my life!"

"Kari is the perfect Zumba teacher.  I couldn't believe how many calories I burned."

"I have used Jenn’s expertise for both group classes and private training and can’t recommend her enough! I have some orthopedic issues that limit what/how I’m able to do certain workouts and she is great about taylor-making them to my accessibility and needs. Most importantly overall though, she’s a blast to work with!"

"Definitely have shown the value of a Trainer.  Knowing the proper form and technique.  And what muscles are being targeted."

"It's been great for people to get back into a group and have some normalcy, physically and mentally.  I think it's really great for people to keep moving."

"Totally recommend for any level of entry into your fitness goals. Classes are fun with great supportive instructor and fellow attendees, very affordable and great follow through with all fitness questions."

"I don't know how Jenn does it with Online Personal Training because she's not there with me doing the workouts, but they're always spot on with what I'm looking for."
