This phrase is popular in the Adirondacks. It can be used to describe a person exhibiting a great feat of strength, but it is most commonly used with a sarcastic connotation to describe a person lifting a lightweight object.
Example #1
Adirondacker 1: *lifts box of books*
Adirondacker 2: Woah, take it easy, Muscle Beach!

Example #2
Adirondacker 1: Instead of taking the fridge, I'll carry this pack of napkins.

Muscles that are gained through working out in a gym and may make a man look strong, but in reality they are gained just for show, like on a beach (hence the name), and therefore are not indicative of toughness or fortitude.
Mike "The Situation" has beach muscles. He looks strong but if he ever got in a fight with someone who was actually tough he would get his ass beat because he only has Beach Muscles.
