This one workout may reduce heart disease risk in women by 20%, says neurologist Dr Sudhir Kumar citing 15-year study

The biggest fitness myth women believe? That cardio is enough. Neurologist Dr Sudhir Kumar explains why strength training matters too.

For years, many women have believed that cardio is the key to fitness while strength training is reserved for men. However, neurologist Dr Sudhir Kumar says this is one of the biggest fitness myths, and scientific evidence tells a very different story.

Taking to X (formerly Twitter), neurologist Dr Sudhir Kumar shared findings from a large study involving over 117,000 women followed for nearly 15 years, highlighting the powerful health benefits of strength training for women.

Strength training significantly lowers heart disease risk

Quoting the study, Dr Kumar wrote, “Women who performed ≥2 hours of strength training per week had a 20 percent lower risk of major cardiovascular disease and a 44 percent lower risk of heart attack compared with women who did no strength training.”

He further explained that even small increases in strength training can make a difference. “Every additional hour of strength training per week was associated with a 5 percent lower risk of major cardiovascular disease and a 14% lower risk of heart attack. This was above and beyond the benefits of aerobic exercise,” he said.

According to Dr Kumar, the greatest health benefits were seen in women who combined:

• At least 150 minutes of moderate aerobic exercise every week
• Two or more hours of strength training weekly
• Less sedentary time

Summing it up, he wrote, “Movement is a team sport; not cardio or weights, but cardio + strength + less sitting.”

Strength training offers more than stronger muscles

Dr Kumar emphasised that lifting weights isn’t just about building muscle. “Strength training is not just about bigger muscles,” he said, adding that it helps:

• Preserve muscle mass
• Improve bone density
• Improve insulin sensitivity
• Lower blood pressure
• Reduce body fat
• Improve balance and reduce the risk of falls
• Enhance overall quality of life

He noted that these benefits become increasingly important as women age.

Will strength training make women bulky

Addressing a common concern, Dr Kumar said, “The reality is that women have much lower testosterone levels than men. Routine strength training makes most women stronger, fitter and healthier, not ‘bulky’.”

Dr Kumar recommends two to three strength-training sessions each week, targeting all major muscle groups. Women can use:

• Dumbbells
• Resistance bands
• Weight machines
• Bodyweight exercises such as squats, lunges and push-ups

He also advised progressing gradually rather than lifting heavy weights from the start.

For women over 40 or 50 who have never lifted weights, Dr Kumar had an encouraging message. “It is not too late. In fact, this may be the time when strength training offers some of its greatest benefits by helping preserve muscle and bone while reducing future health risks,” he wrote.

Dr Kumar concluded with a simple reminder: “For women, strength training is an essential part of healthy ageing. Walk, cycle or swim, but don’t forget to lift.”
