Challenge Is the Secret to Strength Training After 40
Discover why progressive overload is the key to strength training after 40. Build muscle, protect joints, and stay active for decades.
Our muscles, tendons, and ligaments are designed to respond to challenge through adaptation. Adapting is the goal. We want to change to get better at managing life.
The need to adapt gets heightened as we age. If we do nothing, our muscles, tendons, ligaments, connective tissue, and bones weaken. The inactivity that our bodies tolerated in our 30s threatens to limit mobility in our 50s and beyond. The damage can sneak up on you. One day, you rise from the table with ease, and the next, you struggle to get to your feet. When was the last time you felt truly stronger than the month before?

Why Strength Training Matters More as You Age
Strength training after the age of 40 is a crucial part of aging well. Suppose you have the ambition to play pickleball, chase grandchildren, roam Paris, cultivate roses, tango, hawkwatch, swim in the ocean, walk your dog, or engage in any other physical activity. In that case, you need to build the muscles and support the joints (etc.) that do those things.
You don’t need Schwarzenegger muscles — but you do need challenge. Aging well with exercise still takes commitment and effort. Three-pound dumbbells won’t cut it forever. To benefit from resistance training, you must add challenge.
What Is Progressive Overload?
A smart strength training program after 40 adds systematic challenge through a process known as progressive overload. You add work first by picking up the next heavier weight. Additional variables include the number of reps, the number of sets, the tempo of the lift, the length of rest, and the type of exercise.
Resistance training intentionally causes micro tears in the muscle fibers. We work out on day 1 and not again until day 3. The in-between time is for recovery.
With the help of sleep and good nutrition, our body repairs the muscles. The repair isn’t just stitching things back together, but rebuilding them stronger, thicker, and more resilient.
Muscle growth is influenced by how hard you work, genetics, gender, and nutrition. The cycle repeats every time you add challenge: train, recover, grow.
Skip the recovery and you risk fatigue or injury. Skip the challenge and there’s no reason for your body to change.
Two sessions a week now can give you decades of mobility later. Challenge sparks adaptation. Recovery builds strength. Together they keep you vibrant.
Top Benefits of Strength Training for People Over 40
The first benefit of strength training after 40 is that you become stronger for everything you want to do in life. The benefits compound from there.
I’ve compiled a list of 100 for people over 40 (most of which benefit younger people too.) Here are my top 10 resistance training health benefits:
1. Boosts resting metabolism
2. Builds bone density
3. Prevents back injuries
4. Studies show resistance training not only builds muscle, but lengthens telomeres — markers of cellular aging.
5. Eases falling asleep
6. Sit/stand from the floor unassisted
7. Build full-body discipline
8. Stronger grip = longer life
9. Doctors will notice
10. Do what you love for decades
How to Get Started Safely and Effectively
Your future self is built today (and every day). You can create a safe workout over 40 at home using your bodyweight and resistance bands. Strength training beginners can start with these three exercises: 1) Sit and stand 10 x; 2) Do 10 push-ups on a wall; and 3) Step up and down on a stair 10 x per side. If you prefer access to all the toys, you can join a gym.
