"The level of commitment Brett has for physical fitness is second to none. It’s not just about looking good in the mirror. It’s about getting the most out of your body and doing so in a way that is sustainable. If you’re like me you’ll be less tired AND see better results."
"I really benefited from LNGVTY mobile training. It's really great to workout in the beautiful outdoors! The workouts are fun and challenging. I would highly recommend it! "
"His knowledge & unique training skills are the perfect blend to keep me motivated, by seeing results, but without feeling overworked. He uses simple movements, booty bands, and a roller - that’s it. Brett has transformed the way I think of fitness. I’ve lost close to 100lbs and my body wouldn’t be this fit if I didn’t have Brett supporting my new lifestyle."
"Brett has been a fundamental part of my journey to get in shape and lose 100lbs over the past few years. Brett has kept me healthy and focused on the right things while working my body very hard to achieve my goals. He has provided great outdoor in-person workouts when it's possible. I would highly recommend Brett to anyone looking for a fitness/strength trainer."
"With Brett's help I've become much stronger than I would have ever thought possible! I have better posture, have been sleeping better, and I feel more confident about my body."
"My desk job had me feeling weak and tired overall. With training, my posture improved and my chronic neck pain went away! Brett is so knowledgeable about the mechanics and anatomy of the body and is able to explain the reasons behind everything he does."
