Uncomplicate Exercise
But you don’t need a fitness tracker-induced identity crisis. You need consistency, not perfection. The other day someone asked me, “Doc, I’ve started walking 20 minutes every day. That’s good enough, right?”
A 58-year-old banker came to me recently. She walked every day but still felt stiff and fatigued. Diabetes was looming. She feared falling. And she had zero interest in going to a gym. We added resistance bands, some simple balance drills, and hip mobility stretches at night. Eight weeks later, her blood sugars were lower, her energy was up, and she hadn't tripped once. Her dog got fitter too, thanks to her newfound enthusiasm for evening walks. Sometimes the fix can be simple.
So what does movement actually do for you?
Your muscles literally mop up sugar from your bloodstream, no insulin required. Regular movement keeps chronic inflammation in check. It improves insulin sensitivity, cortisol rhythm, and sex hormones, and helps you sleep better. Physical activity also boosts endorphins, dopamine, and BDNF, which is essentially fertiliser for your brain.
The good news is you don't need a fitness tracker or a gym membership. You need consistency.
Someone asked me recently, "Doc, I've started walking 20 minutes every day. That's good enough, right?" It's a great start. But walking alone doesn't cover everything your body needs. If you want to use movement as medicine, for metabolism, hormones, immunity, and longevity, you need to understand that it rests on four pillars.
Endurance (Aerobic Activity)
Walking, jogging, cycling, swimming, anything that gets your heart rate up and makes you breathe a little harder. This is what most people picture when they think of exercise, and for good reason.
It boosts cardiovascular fitness and oxygen efficiency, improves mitochondrial function, enhances insulin sensitivity, increases BDNF, and helps with mood and sleep. Brisk walks, stairs, dancing around your house, all of it counts. That said, endurance training alone leaves a lot on the table.
Resistance (Strength Training)
When most people hear "strength training," they picture a bulky bodybuilder. Many women immediately worry about getting bulky. You won't, unless that's specifically what you're training for.
Muscles are metabolically active, hormonally supportive, and one of your best tools for longevity. Strength training increases your resting metabolic rate, improves blood sugar control, prevents age-related muscle loss (sarcopenia), reduces your risk of falls and osteoporosis, and boosts myokines, which are anti-inflammatory signals released by muscle tissue.
You don't need a squat rack. Resistance bands, bodyweight exercises, or even carrying groceries works. Aim for at least two days a week.
Balance
Most people don't think about balance until they trip over their pet or twist an ankle stepping off a curb. Particularly as you get older, it deserves more attention.
Good balance prevents injuries, improves coordination and reaction time, supports posture, and helps your brain stay oriented to where your body is in space. Try standing on one leg while brushing your teeth. Try yoga, or walking on uneven ground. Falls are one of the leading causes of mortality in older adults and a significant source of medical expenses. One dedicated session a week goes a long way.
Flexibility (Mobility)
This has nothing to do with becoming a contortionist. It's about keeping your joints free to move without discomfort.
Mobility work reduces injury risk, improves range of motion, makes everyday tasks easier, and speeds up recovery. Dynamic stretches before activity, static stretches after. Foam rolling counts. If you can't remember the last time you stretched, that's your sign to start.
Your body works across all these dimensions, and your movement routine should reflect that. The goal isn't to crush workouts. It's to be able to lift your bags, climb stairs comfortably, and show up fully in your daily life for years to come.
Start somewhere. Just don't stop.

Can you drink a glass of poison and wait for your liver to do the magic? Or do you expect to land in the hospital? Given the number of people who die of poisoning, the answer is quite clear.
Can exercise cure depression?
A journalist later wanted to write about and wanted to speak to some of my patients. When she heard the story from her, she declined to write. “This sounds like voodoo,” she said. “Depression can’t be cured in a week. While she didn't say it to my face, she probably thought I was a quack too!
