How does a strain injure you?

Answer:

Muscles are made of meat. Meat's kinda like rubber. Ever pull on a big thick rubber band for a long time until it stopped cinching back to the smaller size? Well, it's just like that.

The muscles are too sore to continue working, so they go to default relaxed state.
