Title:
The surprising reason our muscles get tired
Speaker:
Christian Moro
Description:

You're lifting weights. The first time feels easy, but each lift takes more and more effort until you can't continue. Inside your arms, the muscles responsible for the lifting have become unable to contract. What's going on? Christian Moro explains how exactly our muscles operate, and what causes them to become fatigued. [Directed by Nichola Latzgo, narrated by Addison Anderson].
