Some of us are naturally prone to thicker calf muscles, sometimes due to genetics and other times as a result of physical exercise. Neuromodulators, such as Botox, can slim down calf muscles. Botox is injected into the gastrocnemius muscle. The gastrocnemius muscle is the most superficial calf muscle that is responsible for bulkiness and definition of the calf. Botox causes this muscle to relax, creating a leaner appearance in the leg. This procedure only affects a small proportion of the outer muscle fibers, meaning it does not restrict normal calf function, nor does it negatively affect you ability to walk or run.
