ABOUT JENNA

↓

I can’t wait to help you reach your fullest potential.

I’m Jenna, and I am so happy to introduce you to The Philasophy—a space where I help all individuals ditch the toxic dieting cycle so they can empower themselves through delicious food and feel good fitness instead!

I am an ACE Certified Personal Trainer, AFPA Certified Nutritional Guide and Mad Dogg Certified Spinning Instructor living in the city of brotherly love. My passion for health and wellness started out as a need to finally kick my own harmful habits to the curb and learn how to sustain a lifestyle that was free from food restrictions and over-exercising.

I started dieting at the young age of 13, and when I tell you I tried everything... I mean I tried EVERYTHING—Weight Watchers, Jenny Craig, Atkins, South Beach, Curves, Tone It Up...I can go on and on! Eventually I became so mentally and physically exhausted that I knew enough was enough. In my early 20s I stopped dieting, scrapped the workouts I hated and began a new kind of wellness journey, one that I actually enjoyed! My transformation certainly didn’t happen overnight, but through a lot of trial and error I’m living in a way that I know I can maintain for years to come and I would love to help you do the same!

Kind Words About The Philasophy

“To say I was a bit stuck in my routine is an understatement. I was always an active person but after a few years could not find my niche whether it was due to work or family responsibilities or simply just getting there, even the gym or Pilates studio was stressful.

During work shut downs due to the pandemic, my daughter introduced me to Jenna Stern and working out one on one. This was the answer I’ve been looking for.

Not only is it convenient, Jenna is a knowledgeable trainer who creates workout routines that are for your ability and strength. She also encourages and guides you each step of the way.

I’ve been training close to one year now and am very pleased with my progress. Jenna not only builds strength but confidence as well. As an instructor she is the best.”

“After months of feeling downright defeated and unsure of where to begin, I finally mustered up the courage to send Jenna a message. I was specifically interested in one-on-one training with a professional female, and it’s been the best decision I’ve ever made for myself!

Jenna is a ray of sunshine. She is encouraging, motivating, and very thorough with her explanations and visuals to demonstrate proper technique and form to ensure you are safely and effectively achieving your fitness goals. The tools and support that Jenna has constantly provided me with have shown me a new side of myself! I wake up each day feeling stronger and more confident in my body and abilities. Jenna has taught me that fitness isn’t all about weights, cardio or diet. Being fit is about being ALIVE and getting most out of life.

Working out no longer feels like an obligation I dread. Forever grateful for all that Jenna has done to shift my perspective and offer me all the support I need to make lifestyle changes, I’ll be reaping the benefits for years to come! ”
