What is the one workout could give your body an anti-cancer boost?

You already know exercise can help your heart, waistline, and mood, but now it may have another trick up its sweaty sleeve. Researchers at Edith Cowan University found that a single session of resistance training or high intensity interval training (HIIT) could increase anti cancer proteins released by muscles, known as myokines. In laboratory testing, those changes were linked with a 20 to 30 percent reduction in cancer cell growth. Suddenly that workout you nearly skipped looks very smug indeed!

The study focused on survivors of breast cancer, showing that even after the physical demands of treatment, the body could still respond quickly to exercise. Researchers measured blood samples before exercise, immediately after, and 30 minutes later. Both training styles increased helpful myokines, with notable rises in markers such as IL 6 and decorin. Lead researcher Francesco Bettariga said exercise has emerged as a therapeutic intervention in cancer management, pointing to strong evidence that it is safe and effective during and after treatment.  

What does that mean for you? Your muscles are not just there to carry shopping bags and climb up stairs. When you exercise, they release compounds that may help regulate inflammation and influence cancer biology. Senior author Robert U. Newton said the findings help explain why regular physical activity is linked with lower risk of cancer progression, recurrence, and mortality. That is a very impressive return on investment for 30 minutes of effort.

Before you start calling burpees a miracle cure, an important reality check. This does not mean one workout cures cancer, and it does not replace screening, medical treatment, or professional care. It does suggest that movement can be a powerful ally. Bettariga also noted that reducing body fat while preserving or building lean muscle may help lower chronic inflammation, a factor tied to recurrence and poorer outcomes.

So if you can move regularly, even imperfectly, your body is likely taking notes and quietly thanking you later.
