An hour a week with your therapist or trainer helps. But it's the other 166 hours that change your muscles. FIS OnDemand gives you joint-smart strength workouts you can actually keep up with, so consistency does what a once-a-week appointment can't.
Then $19.99/month. Cancel anytime. No equipment needed to start.
If you're tired of joint pain, feeling weaker than you used to, or spending more time nursing injuries than working out, you're not alone. Most people over 50 don't stall because they stopped trying. They stall because they're training a 55-year-old body with a 30-year-old plan. FIS OnDemand reconnects your weak muscles, stabilizes your joints, and rebuilds strength in the right order, so you can move without bracing for the next flare-up.
These are members writing to Lauren in their own words.
Pain-free for the first time in 20 years.
Thirty years of crippling back strain. No more.
At 71, my bone density improved, and I was only hoping to maintain.
"Lauren these videos have changed my life. When I consistently do my program I feel awesome. When I don't do it my body unravels. This is the first time in years I've found something that truly works. I do this first thing in the morning to 'set' my body. Thank you for giving me back my life and my health."
Polly"Too many people just want a pill to make them feel better. But you actually need to move properly and functionally. Lauren is the most forward-thinking fitness expert I've ever trained with. Everything she says and does is backed by research, science, and years of experience."
Beth"To all my friends dealing with muscle weakness, joint issues, torn ligaments, hip concerns and more, I can't recommend Lauren enough. I've been her client for years, dating back to my first hip surgery, working with her both before and after each one."
Caroline"I can step onto a mat feeling blah and sore from all the sitting I do at my job, and after even a short workout I feel so much better. I take Lauren with me when I travel, because the app has plenty of workouts that don't require props or equipment."

Lauren Eirk has spent nearly four decades studying how the body actually builds strength as it ages. As a Muscle Activation Techniques Specialist and an educator to health professionals nationwide, she created FIS OnDemand to bring joint-smart strength training to adults over 50, the people who need it most and are usually left out.
She teaches the "why" behind every movement, and she answers members by name. You're not buying a video library. You're training with a coach who shows up.
Strength you can trust starts by preparing the muscle before you load the joint. Each step builds on the last, so your body adapts instead of breaking down.
Wake up weak, quiet muscles with isolated isometrics to restore proper activation.
Train muscles to work together through controlled, multi-joint isometric holds.
Build strength through controlled movement using bodyweight and joint-focused training.
Add resistance with weights and bands once your body is prepared for the load.
Progress to dynamic, stability-based training for lasting endurance and resilience.
The method works in one direction: from weak and guarded to strong and confident.
Most apps hand you a video library and wish you luck. Lauren shows up. She answers members by name in the community, teaches the reasoning behind every movement, and hosts live coaching so you always know your next step.
