About-Me2Jenn Brown- Longsworth

Master Personal Trainer

I am IN LOVE with what I do! I began my career as a Certified Personal Trainer in 2005 and started my own business, Fitness Is a Lifestyle, in 2006. Fit Style emerged from that in 2014 and is now an ever-expanding business.  Working out is my passion, and I love being able to help other people develop the same love for health and fitness that I have.

My ultimate objective with Fit Style is to help people feel good about themselves. Self-confidence (I believe) is the key to all success in life, and nothing builds self-confidence better than a strong, lean, healthy body. I love helping people realize their physical potential, and being there when they break through mental barriers by doing things they never thought their bodies could.
I am ecstatic about life and the opportunity that Personal Training affords me to share my excitement with others – it’s amazing to see my clients’ attitudes change right before my eyes some days! I do what I love and love what I do, and if I can help even one person improve their quality of life through fitness, I have met my goal.

Master Personal Trainer

I have been a personal trainer since 2010 and am excited to bring my knowledge to the Fit Style team. I am a nationally qualified bodybuilder specializing in nutrition, functional training, sports performance and competition prep/offseason training.

Guiding my clients through their success journeys is what brings much life into my area of work. I am eager to help clients exceed their goals by tailoring workouts to meet their specific needs and interests as well as coming up with a nutrition plan that compliments their fitness goals.

I love sharing my passion and knowledge with others, and look forward to challenging new clients to be their very best!



Maegan Swain,

My relationship with fitness started about 12 years ago when I reached a breaking point with myself. I was overweight and very unhealthy, so I started weight lifting & researching how to eat correctly. After successfully losing 30 lbs, the help of a trainer & a lot of dedication, I decided to get more disciplined and I began competing in the NPC. I did my 1st figure competition in 2008 & since then have competed in over a dozen competitions.
Prepping for shows not only transformed my body but it allowed me to become more disciplined in many other areas of my life. I learned a lot about myself & how far you really can push yourself.

Over the past several years I have developed a deep appreciation for exercise science & nutrition. I have completely embraced the lifestyle through consistency and adopting healthy habits. I want to share this love for nutrition & fitness with everyone who wants it! It is my pursuit and passion to help you reach your goals & create a lifestyle where you can KEEP those goals.
