Fit & Fierce Over 40

10 Lessons / with Sadie Nardini

Shed Hormonal Belly and Weight Gain And Get Strong At Any Age!


Yoga Shred workouts – a combination of HIIT and yoga, to give you the whole body strength, stamina and cardio optimization you need to age your best.

A comprehensive fitness program that’s also efficient so you can fit it seamlessly into your busy life. 

Targeted solutions for common areas that tend to decline as we age: hormonal balance, pelvic floor strength, strong glutes, shoulder mobility and more!

What it is:

Joint-Safer High Intensity Interval Training Sessions: The Best Workout In The Least Time.

In this course, you get 10 invigorating and exclusive Yoga Shred® classes, each a whole body workout, with a focus on specific areas we need to age well. You won’t find these anywhere else!

Short Sessions With Incredible Results

Every class is 30 minutes or less! It’s easy to replace some mindless screen time with one of these.

You can keep them forever, and return to them anytime you want to be sure you’re getting the best exercise with the safest instruction.

Stay Safer and Stronger for A Lifetime

Each session includes a How To tutorial for each main pose in the workout. This will help you get the most benefits out of your short time on the mat, and any class you attend out in the world.

I want this course!


What’s included:

10 of Sadie’s Signature Fit & Fierce Over 40 Yoga Shred® Classes

Strong and modified movements for those over 40. Work smarter, and you’ll get the same lifting, toning, lean body, and vital glow in minutes that you used to get by going hard at the gym or on the yoga mat.

Sessions That Keep You Aging Fiercely!

Aging doesn’t have to slow you down. These classes all focus on areas of your health and fitness you need to build up so life doesn’t tear you down. From hormonal balance, deeper core strength, balance, metabolism and cardio boosting, and knee-safer light impact – this one course will help you age holistically well. 

Strong but Approachable Classes

This course is for already strong, generally able-bodied students and teachers over 40. You should be able to work out and want to keep building next-level muscle tone, endurance and fitness, but want to learn a more efficient, age appropriate and sustainable way to do so.

What you need to take this course:

A yoga mat, 2 yoga blocks recommended.

Two light (1/2-5 lb) hand or wrist weights, and ankle weights optional but recommended. 

Fit Fierce and over 40-2

You can’t turn back the clock, but you CAN become the best, most vibrant, energized, confident and strong version of yourself. And a lot faster than you think.

There are some pervasive myths about aging: that people over 40 start to lose a lot of strength and muscle tone or that your metabolism slows down each year.

None of this is actually not supported by science and we now know that if you keep strength training, you won’t naturally have any metabolic decline until around age 60. Even then it’s not much – and can be turned around through exercise.

A lot of the sluggishness and weakness we associate with aging can be avoided or even reversed by building lean muscle mass and regularly moving intensely, for short bursts. But as we age, we have to balance working out strongly with mindful joint health. In this course, you’ll do both!


“I just wanted to say how life changing your classes are. I don’t know why but there’s something SO refreshingly different about your workouts. I hate exercising and I never stick to any workout routine, but for some reason I find myself looking forward to yours!
 I just wanted to say a big thank you! I’m a massive fan and I’m so glad I started this course.”

– Elisabeth, 48

“Finally, a yoga class that burns in all the right ways! And leaves the athletes I teach feeling accomplished instead of bored. My body has never felt stronger!”

– Clara, 50

“I have been an online student of yours for years. Your approach to respecting individual anatomical limits, intentional movement and empowering attitude have totally transformed my practice on the mat, and off.”

– Anne, 57
