K

This is perhaps the shortest blog post in the history of blog posts.
The lesson: when you work out hard, eat bananas.
The reason: They contain potassium , which is an element that helps cell, tissue and muscle function. Also, they play a major role in muscle contraction ( the reason why you get sore ). I promise if you eat a banana after a work out you will not be nearly as sore the next day.
Conclusion: Bananas rock because of their K.
