As we move through our 30s, 40s, and beyond, our hormones, metabolism, and recovery shift.

Our training should shift with it.

I’m not coaching from the outside.

I’m a certified personal trainer — and I’m living this stage too. I understand the muscle changes, joint stiffness, energy swings, and mental load that come with it.

At Shift by Jeni, I focus on what actually works now:

• Build and maintain lean muscle

• Support metabolism naturally

• Improve mobility and joint health

• Increase energy — not exhaustion

• Train with structure and progression

Challenging, structured workouts. Progress you can feel.

Strength training that supports your body - and pushes it forward.

Train with Purpose. Get Results.

Whether you want 1:1 coaching, group training, or to train from home — there’s a path here for you.

  • Client Testimonials:

    “I am 64 years young and real fitness has been an elusive goal of mine. I have spent years on and (mostly) off trying to find a personal trainer in the gym setting to get me to where I wanted to be physically. Frustrated by their inattention, lack of knowledge and unfortunately youth, I gave up time and time again. When I moved to Napa I ran across Jeni’s website by accident. I called her and set up my first appointment at my home. That was 4 1/2 years ago. Today I am stronger and more confident physically than I have ever been. Jeni has taken me on an incredible journey.  She is personable, knowledgeable, patient and above all professional. She believed in me and I truly believe in her. I highly recommend Jeni as a personal trainer. Give her a call. But you won’t get my daily spot. I’m never leaving!”

  • Client Testimonials:

    “Jeni is amazing!! I have been going to Jeni’s bootcamp since I moved to napa 10 years ago. The results, the camaraderie with the other ladies in my classes, and the challenges that Jeni brings to every session have kept me committed.  I could not recommend Jeni’s bootcamp more for anyone who is looking to build strength, build community, and have an amazing time looking and feeling your best!”

  • Client Testimonials:

    “I have been working out with Jeni every Tuesday and Wednesday morning for 2+ years and 250+ classes now. Jeni’s positive encouragement and well thought out lessons keeps my body challenged, even after all the classes we’ve had together! Over the years I have lost 70+lbs and for the first time in my life maintained the weight loss without fluctuation. I have never been so strong, I can do multiple full push ups, I can stand from sitting without using my hands, but most importantly I can keep up with my kids and work, something I was genuinely struggling with just a few years ago. Jeni makes it easy to show up (even for people like me, who is not a fan of the early morning!) by building up intensity and bringing her own encouraging energy to help get us moving! Jeni has been a consistently positive and healthy addition to my life, I look forward to my exercise days every week. I am excited to learn what else my body can do every week, and I have Jeni to thank for that.”

  • Client Testimonials:

    “Jeni has been my trainer for the past 7 years and my life would not be the same without her!  I’m 73 and strong, nimble, with good balance and endurance.  I have worked out with her online, whether I’m at home, visiting family or friends, camping by the ocean or in the mountains, across the country, or out of the country!  She greets me 4 mornings a week with a smile and a workout plan! ”

    — Dee M.

  • Cient Testimonials:

    “I’ve exercised for most of my life and have always enjoyed it until I turned 50 and hit a fitness slump. I was frustrated and annoyed that my usual exercise routine wasn’t working and then I met Jeni. Whether it’s a 1:1 session or bootcamp (I do both), she has the innate ability to read the room and tailor her workouts to match your energy level. Bootcamp is a great break from a stressful workday and I always leave with more energy than I started with. Jeni is my biggest cheerleader since day one, pushing me out of my comfort zone and challenging me to work harder. She has helped me realize I’m stronger that I know and I should trust my abilities. I’m excited to continue my fitness journey with her.”
