Did You Know!

Some muscle disorders can cause your muscles to become stronger-looking while actually making them weaker.

Certain muscle diseases, including Duchenne and Becker muscular dystrophy, can cause a condition known as pseudohypertrophy. This happens when muscle tissue is gradually replaced by fat and connective tissue, making the muscles appear unusually large. The calf muscles are particularly vulnerable. Despite their larger appearance, these muscles may actually be losing strength.
