Does this sound like you?
If your body feels different than it used to, you're not alone—and you don't have to figure it out by yourself.
You used to feel stronger.
Daily activities and workouts don't feel as easy as they once did.
Exercise Feels More Confusing
You're not sure what's safe, effective, or right for your body anymore.
You've Lost Confidence
You're worried about making your joints worse or getting injured.
You're Ready for a Better Plan
You want a progressive approach that builds strength instead of piecing together random workouts.
Hi, I'm Lauren!
I've spent over 40 years helping adults over 50 rebuild strength, improve movement, and regain confidence in their bodies.
After navigating my own injuries and setbacks, I learned that not every body responds well to traditional fitness.
That's why I created the 5-Step Isometric Method™—a progressive approach that helps you rebuild strength safely and confidently, one step at a time.
Imagine How You'll Feel Just One Week From Now
Stronger muscles that better support your joints
Improved mobility and easier everyday movement
More confidence knowing you're exercising the right way
A clear path forward instead of guessing what to do next
Your FREE 7-Day Strength Experience
Most exercise programs ask your body to do
too much, too soon.
The FIS Progressive Strength Method follows a different path.

"These videos have changed my life! I have had this app for over a year and when I consistently do my program I feel awesome. When I don't do it my body unravels. This is the first time in the years I have found something that truly works. Who doesn't have 15 to 30 minutes in their day to take care of their body? I do this first thing in the morning to "set" my body. Thank you for giving me back my life and my health!!

"Nothing like it! You will never find another app that you can use for Fitness And rehab rehabilitation for any injury or pain you have. Too many people just want a pill to make them feel better in their body, but you actually need to move properly and functionally. Lauren Eirk is the most forward thinking fitness expert I’ve ever met and trained with. She really cares about what she’s teaching to truly help people. Everything she says, and does is backed by research and science and years of experience."
Beth Kitchen
"In my 50s and 60s I kept trying to do the same strength training workouts that I did in my 30s and 40s, only to spend more time nursing injuries and I did working out. I experiment it was several different approaches to Fitness And and doing so discovered Lauren Eirk and FIS. After finding Lauren's program, I am pain-free for the first time in 20 years! My body is much more stable, balanced and mobile."
