At 49, my body changed in what seemed like overnight. My athletic, toned body suddenly got soft and blobby. My arms had lost their definition. My clothes didn’t fit anymore: I felt like a sausage packed too tightly in its skin.
I was embarrassed and frustrated. My go-to exercise and diet routines that had kept me looking and feeling amazing for decades didn't work anymore.
I avoided looking in the mirror, dimmed the bedroom lights, and chose looser clothes.
My outside felt completely disconnected from my inside. On the inside, I was thriving mentally, emotionally, and socially after my divorce and perimenopause. On the outside, I was going downhill. It felt so unfair.
I turned my focus to building muscle and transformed my body into one that is stronger and leaner than ever before. I am proud of what my body can do, and of what I see in the mirror.
My toned arms are back, and so is my mojo.
I walked into my college reunion feeling like a woman in her prime: confident, strong, and finally looking on the outside the way I felt on the inside.
Getting my body back changed everything. And the thing is that I am not special. I just finally understood how to work with my midlife body.
Since then, I've been on a mission to help other women do it too. Imagine walking into summer feeling strong, toned, and completely at home in your own skin: excited for that sleeveless dress.
The body you want to spend the rest of your life in is waiting for you. You just need the right plan.

Robin followed the Learn to Lift at HOME program for 10 weeks, training just twice a week with dumbbells and what a difference it made. She not only got stronger, she lost visceral fat.
Her clothes fit better, and she feels amazing in her body again!
You can do it too!


If you’ve been told you should be lifting weights to improve body composition, prevent muscle loss, improve blood sugar regulation or bone density, and/or help your body age well, this is the program for you!
There are so many workouts out there that call themselves 'strength training' but are really just workouts with weights. They don't follow the science of building muscle and strength, which means that no matter how hard you work, they're not going to get the results you deserve.
Learn to Lift is different. It applies proven methods for building muscle and strength while accounting for the realities of a midlife body. That’s what makes it doable even if you've never lifted before. And it's why my members get stronger and healthier and see real results after just 10 weeks.
P.S. if you're on a GLP-1 or other weightloss program and your doctor told you to lift weights to preserve muscle and bone, this is exactly the kind of strength training they're talking about.
An easy-to-follow 10-week strength training program: the most effective and efficient way to build lean muscle & strengthen your whole body.

"I finally know what to do"
“I had wanted to start weight training for a long time but didn't really know what to do. Lynn's program made it easy, and she was there to help whenever I had questions. Now, I lift weights regularly. What I love best is how empowered it makes me feel!" - Nina

"Finally, real strength training"
"I'm not new to weights, but definitely new to progressive strength training. I was guilty of going to the workout classes doing the light weights and tons of reps. I'm looking forward to getting stronger and hopefully losing a few inches while doing it!" - Kerri

"I love my new body"
"None of my clothes fit anymore but I'm not really complaining. I love my new body, it's in the best shape of my life at age 40." - Laura

"Stronger in my everyday life"
"During the past 3 weeks, I've completed 7 workouts, and I'm very much enjoying it! Already, it makes me feel stronger during my daily activities." - Lasma

"My clothes fit so much better after 4 weeks"
"I am now one month in thanks to Lynn, and the changes are enormous already! I am doing all this from home with 5, 10 and 15 lb dumbbells so far! My clothes fit so much better after 4 weeks. Progressive overload is really making me stronger already!"- Sara, 63

"I love that it's go at your own pace"
"3 days a week is totally doable for me! I love the fact that it's go at your own pace and I'm not having to try to keep up with someone who is more advanced than me... 37 minutes flies by with all the rest periods and I don't feel dragging at the end but rather energized."
- Mandi


“Thank you! you have the formula! It’s not a magic potion - but it is without a doubt - a formula for success. I look forward to my continued success with you.” - Beth

I help women in midlife rebuild their strength, energy, and confidence so they can keep doing the things that make life full: hiking the trails they love, keeping up with grandkids, lifting their luggage with ease, and feeling proud of the woman they see in the mirror.
Because this stage of life isn’t about slowing down. It’s about finally feeling at home in your body, owning your power, and stepping into the next decades feeling strong, capable, and yes, beautiful.
My mission is to help you stay independent, vibrant, and full of life for the long run so your body supports everything you still want to do, and everything you haven’t done yet.
You’re not past your prime. You’re entering it. And I’m here to help you have the strength to live it fully.
Ready to feel strong, capable, and confident in your body again? Let’s get started.
Absolutely! Learn to Lift is designed for women who’ve never lifted before or who want to learn to lift properly for better results.
It’s a 10-week. By default, it starts as soon as you sign up.
HOWEVER, if you'd like to delay your start, just let me know, and I'm happy to shift the start date.

You choose 2, 3, or 4 days per week. If you're brand new to strength training, I recommend you start with 2 or 3 days/week. You can always increase later, but consistency is key - so choose a frequency that you can maintain.
I've designed the sessions to be flexible because I know life can get busy, BUT even a short workout is better than no workout.
For that reason, each session has two options: do the 'short' 30minute version or the 'full' version which takes 45–60 minutes.
At home: all you need are some dumbbells and a bit of space (a yoga mat’s worth).
Looking for dumbbells? Check out my favorites here: www.befitafter40.com/stuff
At the gym: I use standard gym equipment, and every exercise includes alternatives if your gym doesn’t have something.
No, you train when it suits you. I’ll guide you on how to schedule your sessions for best recovery.
The key thing is to leave 48 hours between training the same muscle groups again.
I’m here for you! You’ll get access to a private Facebook group and can message me directly in the app anytime.
Yes! The programme is designed for women starting from scratch. You’ll train at your own level and progress safely as your strength grows.
No, Learn to Lift focuses purely on strength training. If fat loss is your goal, I offer a separate course called Midlife Fat Loss Formula.
You'll be invited to continue your journey in my monthly membership, where Learn to Lift grads get a special discounted rate of 20% off.
