Training, nutrition, and staying consistent — notes from Jenna on what actually works in the gym and at home.

Welcome Nov 10, 2026 · By Jenna Rubin

Welcome to the JennaFit Blog

This is where I'll share the same straightforward advice I give my clients in session.

My approach is simple: make sure you enjoy exercise and stay consistent. If you don't enjoy it, you won't stick with it — and consistency is what changes your strength, health, and body over time.

Expect posts on strength training and form, building a routine you can actually keep, nutrition basics, mobility and yoga for recovery, and training safely as you get older. No fads, no hype — just what to do, why it matters, and how to fit it into a real week.

New entries will be added here as they're written. If there's a topic you want covered, ask me in session or message me on Instagram.

Enjoy it. Stay consistent.

JennaFit is Jenna's personal training business in San Diego. Her goal is to make sure you enjoy exercise and stay consistent — if you don't enjoy it, you won't stick with it, and consistency is what actually changes your strength, health, and body over time. Training is direct and straightforward: you set a goal, you get a plan built to be doable and enjoyable for you, and you put in the work — with coaching on form and progress at every session. Jenna graduated top of her class in exercise science from SUNY Cortland.

Jenna brings more than personal training to your sessions. She's a Precision Nutrition coach for nutrition guidance, a Girls Gone Strong coach, and a strength and conditioning coach — so your training, conditioning, and food can all work toward the same goal. As a NASM Senior Fitness Specialist, she's also specifically trained to coach older adults safely and effectively, with programming that supports strength, balance, mobility, and independence.

She's also a gymnast and a skateboarder, and that athletic background shows up in how she coaches: body control, balance, mobility, and strength that carries over to real life and sport.

Whether you're new to the gym, coming back after time off, or training for a specific goal, sessions are built around your experience level and any limitations you have. Strength training is the foundation, with yoga and mobility woven in to keep you moving well. Train at Lionstrong Athletics, 7733 Othello Ave, San Diego, CA 92111 in Kearny Mesa, or book a home visit — Jenna also trains clients at home across San Diego.

Common questions

Where do sessions take place?

At Lionstrong Athletics, 7733 Othello Ave, San Diego, CA 92111 in Kearny Mesa — or at your home. Jenna also does home visits across San Diego, so you can train at home if that's easier for your schedule, with the same coaching and programming. Note your preference — Lionstrong Athletics or home visit — on the Interest Form.

Do you do home visits?

Yes. Jenna also does home visits in addition to training at Lionstrong Athletics. If you prefer to train at home, Jenna will come to you in San Diego with the same coaching and a plan built around your goals and the space and equipment you have. Choose home visit on the Interest Form.

How do I get started?

Fill out the New Client Interest Form linked on this page. It asks for your name, contact info, goals, experience, how many sessions a week you want, your availability, and any injuries or limitations. Jenna will follow up from there.

What's the difference between a subscription and a package?

A subscription is a set number of sessions every week — 1×, 2×, or 3× a week, billed monthly at $400, $760, or $1,080. A package is a prepaid block of 5, 10, or 20 sessions you use at your own pace. Per-session prices are the same either way: the more you train, the less each session costs.

Can I train with a friend?

Yes. Split any session package with a friend and train together — 5 sessions is $250 each, 10 sessions is $475 each, and 20 sessions is $850 each.

What is small group training?

Small group sessions are $40 per person. You get coaching and a shared workout in a small group setting — a good lower-cost option if you like training with other people.

Do you train older adults?

Yes. Jenna is a NASM Senior Fitness Specialist, in addition to being a NASM Certified Personal Trainer. That means she's specifically trained to coach older adults — with a focus on strength, balance, mobility, and safe progressions adjusted to your experience, health, and any limitations. Note those details on the Interest Form so your plan can be built around them.

I've never worked out / I have an injury. Can I still train?

Yes — note your experience and any injuries or limitations on the Interest Form so your plan can be built around them. Sessions are adjusted to your level. Jenna's approach is to make exercise something you enjoy and can stay consistent with, not something you dread.

How does the referral offer work?

Refer someone who signs up for training and you get a week of training free.
