Does running make legs bigger?
Your legs get bigger if it’s a struggle to do 5 or 6 or 7 reps of whatever movement you’re performing. Your legs CAN get bigger if you’re sprinting. In distance running you are performing hundreds and thousands of reps. ALSO, for a muscle to grow, you need to be consuming more calories than you’re spending. If YOU AREN’T, your legs will not grow. If you are consuming fewer calories than you’re spending, you will lose fat.
