Strength Training Could Slash Women’s Heart Disease Risk by 20%, Study Finds

For years many of us have been told that a steady jog or a long bike ride is the holy grail of fitness, especially for women. Cardio, they say, is everything. But a recent, massive study is flipping that narrative on its head.

Neurologist Dr Sudhir Kumar, who shares health insights on X (formerly Twitter), highlighted findings from a 15‑year follow‑up of 117,000 plus women. The numbers are striking: women who clocked at least two hours of strength training each week faced a 20 % lower chance of major cardiovascular disease and a staggering 44 % lower risk of a heart attack compared with those who never lifted a weight.

Even modest increments matter. Dr Kumar notes that every extra hour of strength work per week shaved off about 5 % of the risk for major cardiovascular events and sliced 14 % off the heart‑attack risk. And that’s on top of any cardio benefits you’re already racking up.

What’s the sweet spot? The study suggests the biggest health payoff comes when women blend:

• At least 150 minutes of moderate aerobic activity each week (think brisk walks, cycling or swimming),
• Two or more hours of strength training weekly, and
• Less time spent sitting.

In Dr Kumar’s own words, “Movement is a team sport; not cardio or weights, but cardio + strength + less sitting.” It’s a reminder that a balanced routine beats any single‑track approach.

Beyond protecting the heart, strength training does a lot more than bulk up muscles. It helps preserve muscle mass as we age, boosts bone density, improves insulin sensitivity, lowers blood pressure, trims body fat, sharpens balance (which can prevent falls), and generally lifts quality of life. All of these perks become increasingly valuable as women move into middle age and beyond.

Some women worry that lifting will turn them into bodybuilders. The reality? Women have far lower testosterone than men, so routine strength work typically makes you stronger and fitter, not bulky. You’ll notice more tone, stamina, and confidence, not a sudden need for a bigger wardrobe.

So, how often should you hit the weights? Dr Kumar recommends two to three sessions a week, targeting all major muscle groups. You don’t need an expensive gym – dumbbells, resistance bands, body‑weight moves like squats, lunges, and push‑ups work just fine. The key is to start light, focus on form, and progress gradually.

For anyone over 40 or 50 who’s never lifted before, the news is encouraging: it’s never too late. In fact, strength training can be especially potent at this stage, helping to preserve muscle and bone while cutting future health risks.

Bottom line? Women should pair their usual walks, cycles, or swims with a bit of strength work. Think of it as adding a missing piece to the puzzle of healthy ageing. As Dr Kumar puts it, “Walk, cycle or swim, but don’t forget to lift.”
