Define "run a lot"
"Burning muscle" has more to do with an inadequate diet and poor nutritional intake timing when activity levels are high as opposed to running too much.
Not strengthening tendons and ligaments,poor lifting or running form, not giving body adequate time to recover and poor/non-existent warm-up/cool-down make you prone to injuries. Not, lack of muscle.
