I love training at TruFit! I’ve gotten a lot of injuries from being an athlete and not getting the proper training, but Kayla has helped me so much by gaining my strength back. TruFit has such a great atmosphere, and the trainers motivate you and push you to do your best!

When I started training with Luke, I weighed thirty more pounds and hated exercise. Through his advice, support, and expertise, exercise is now a staple in my week. I feel great and wholeheartedly recommend checking out Valpo TruFit.
