11 knee-friendly weight loss exercises you can try

Losing weight is not a piece of cake. Add knee pain to it, and you will find it more challenging to drop pounds. You can watch your diet by focusing on healthy foods, and giving importance to portion control. But you also need to sweat it out to maintain a healthy weight. Your knee pain will probably hold you back from working out. Whether the pain is due to an injury, arthritis or ageing, you need to keep moving. The good news is that there are knee-friendly weight loss exercises. These exercises can help to lose weight and also reduce knee pain.

Why exercise with bad knees?

If you have knee pain, and don’t engage in physical activity, and lead a sedentary lifestyle, you will gain weight, especially in the abdomen area, over time. Excessive abdominal weight can increase the risk of cardiovascular disease, non-alcoholic fatty liver disease, and type 2 diabetes, as per research published in Frontiers in 2021. Not exercising can even make the pain in your knees worse. Exercising can not only help to lose weight, but also improve knee pain.

A 2002 study published in The BMJ showed that participants who worked out had an average reduction in knee pain of 12 percent. Another study, published in the Journal of Orthopaedic & Sports Physical Therapy in 2018, showed that physical activity for arthritic knee pain often leads to better outcomes than using medications, injections, and undergoing surgery.
