Should you allow your muscles to burn when working out?

A Burning Question. What you refer to as burning, is microtrauma to the muscle tissue that is detected by the pain and stretch fibers. Some of this is normal during vigorous repetitive activity with working out. Caution should be used when the burning or pain persists after several hours as this could suggest a more significant tear, rupture or bleeding. Seek eval if this occurs to r/o a compartment syndrome.
