Hi, I’m Jenn — Let’s Build Your Best Self

A mom, a dance mom, a former national figure champion, a mental health advocate, and someone who’s been through the ups and downs of life, fitness, and hormones firsthand. I’ve spent over 25 years helping women transform their bodies, health, and confidence, from everyday clients to natural bodybuilding competitors reaching the IFBB Pro League.

I started as a personal trainer in 1996, teaching every type of class imaginable — from step to hi-low — and later earned credentials as a Holistic Nutritionist (CSNN), ISSA-certified Fitness Nutritionist, NSCA/BCRPA-certified Personal Trainer, TRX Certified, and Twist Conditioning Specialist. Before opening my business in 2013, I worked in functional wellness for one of Canada’s top 50 managed companies, collaborating with pharmacists, supplement companies, and everyday people to create holistic nutrition and lifestyle strategies that actually work.

✅ I’ve walked my talk: a hysterectomy at 39, decades of body image and weight struggles, competing on stage, and modeling for Microsoft Surface, Oxygen Magazine, and Status Magazine. I know what it’s like to rebuild from the inside out — and that’s exactly what I help my clients do every day.

✅ Through the Jennifer Kersten Method, I’ve guided over 1,000 women to transform their bodies, reclaim confidence, and improve performance using metabolism-focused coaching, strength training, flexible and reverse dieting, mindset strategies, hormonal and gut health optimization, and functional wellness. I’ve also presented at Bodybuilding.com (2016) and contributed to Sohee Lee’s Tracking Macros and Reverse Dieting e-book.

✅ My approach is never cookie-cutter — every program is tailored to your life, your hormones, and your goals. Together, we tackle the root causes of challenges, build sustainable habits, and create results that last.
