How to Build Functional Strength at Any Age
The Science of Strength Masterclass

Are you getting weaker with age? Declining grip strength? Struggling with stairs? Feeling more knee or back pain? The good news is that you can build strength at any age.
Here’s how adding lean muscle will benefit your health:
- Increased bone density
- Improved hormonal balance
- Better metabolism and immunity
- Better mood and cognition
- Reduced joint pain and lower risk of injury
For these reasons, strength is one of the strongest predictors of healthspan and lifespan. However, if you’ve never trained before, it can feel intimidating. You don’t want to get injured, bulk up, or waste time.
Strength is Always Possible
Here’s the truth: strength training done correctly works for anyone, at any age. It doesn’t require hours in the gym or heavy barbells. Just 75 minutes per week of strength training, can help you:
- Improve grip and carry strength
- Be able to get up and down from the floor with ease
- Climb stairs faster, with less fatigue
- Reduce joint pain in your back, knees, and hips
- Feel stronger, more capable, and younger
When most people hear “strength training,” they picture bodybuilders with spray tans and bulging muscles. That is not the goal here. For health and longevity, doctors usually recommend modest lean muscle gains—just a couple of pounds over the course of a year. This is realistic and attainable for anyone, regardless of age.
What is Functional Strength?
Here’s our approach at YOGABODY. We start with bodyweight exercises, progress to resistance bands, and only add weights if useful. The key is training the muscle you already have. Untrained muscle has poor mind-muscle connection and often contains intramuscular fat (like marbled Wagyu beef). Training transforms that same tissue into strong, metabolically active muscle.

My 40+ Muscle Loss Story
For most of my adult life, strength was never a priority. I focused on yoga and cardio. Until I turned 40, that worked great. When we’re younger, our bodies are much better at building and maintaining muscle.
Since I exercised so often, I naturally had sufficient lean muscle for joint stability, blood sugar balance, and lifestyle fitness. But then age hit me.
I started to feel weak. Not frail, but weaker than I wanted to feel. I noticed it when carrying my kids, hauling luggage through the airport, and climbing stairs. My grip strength declined, and everyday tasks felt more difficult.
When I looked at the research, I discovered that most people have a similar experience in middle age. Their lean muscle starts to disappear. What I also learned from the research is that with about 75 minutes per week, most people can make pretty big changes. So, I gave it a try.
Within a little over two years, I’ve gained about 11 pounds of lean muscle, and while you wouldn’t notice it in photos – all my clothes are the same size – I feel it in the power of my lower body and the strength of my upper body in push and pull exercises. The best part? It only takes me 75 minutes per week.
I’d love to do more, but even with this minimum dose, the results are remarkable. That’s why we’ve made strength training an integral part of our teaching at YOGABODY—and you can experience the same transformation.
