WALKING 10,000 STEPS IS GREAT, BUT IT CANNOT STRENGTHEN ONE CRUCIAL BODY PART. HEART SURGEON URGES ADDING ANOTHER EXERCISE TO ROUTINE

A daily walk has long been celebrated as a near-perfect exercise routine. For many, hitting ten thousand steps has become the gold standard for good health. However, a cardiothoracic surgeon is urging people, especially women in midlife, to rethink one key assumption: walking alone cannot strengthen bones.

This insight was shared by Dr Jeremy London in a recent Instagram video posted on his official account where he discussed why many adults may be unknowingly neglecting an essential component of long-term strength and independence. The text on his post read, “Walking does NOT build strong bones.”

Why walking is not enough

Dr London praised walking for its many benefits. In the video, he said it lifts mood, lowers blood pressure, supports metabolic health and helps with weight control. But he emphasised that despite its advantages, walking cannot significantly increase bone mineral density because it does not place enough mechanical load on the skeleton to stimulate bone growth.

According to him, this becomes especially important after midlife when hormonal changes increase the risk of osteopenia and osteoporosis. He explained that relying on steps alone for bone protection can leave many adults vulnerable to weakness and fractures.

The real key to stronger bones

Dr London highlighted resistance training as the most effective tool for improving bone density. In his words, lifting weights places targeted stress on bones, signalling them to grow stronger and more resilient. He stated that research supports moderate to high intensity strength training for strengthening the hip and spine, areas most critical for preventing serious injuries from falls.

“Keep walking. It is fantastic for your overall health,” he said in the clip. “But if you care about long-term bone strength, balance, and preserving independence, pick up weights and train your muscles and your bones.”

A growing conversation around strength versus cardio

His message echoes conversations emerging across fitness circles. As seen in a recent report featuring celebrity fitness trainer Siddhartha Singh, social media users constantly debate the right balance between cardio and strength workouts. Singh, who trains actor Tamannaah Bhatia, advised that those seeking fat loss and toning should begin with strength training because muscles require more energy and help burn calories long after a workout ends.

Experts continue to stress that consistency matters more than perfection and that combining walking, resistance training and flexibility exercises leads to sustainable fitness.

Dr London is a board-certified cardiothoracic surgeon with over 25 years of experience who practices in Savannah, Georgia. Beyond surgery, he advocates for preventative care and lifestyle changes that support healthy aging, drawing from both clinical knowledge and his personal experience as a cardiac patient.

Walking remains an excellent habit for overall wellness and heart health, but relying only on steps could mean missing an essential aspect of aging well. Incorporating weight training, even twice a week, can significantly reduce the risk of fractures, improve balance and ensure independence later in life.
