When SpongeBob realizes that he is extremely weak, he asks Sandy to help him workout. However, Sandy's methods prove far too intense and painful for him, and he runs back home. At home, he sees an ad on TV for a product called "Anchor Arms", which are inflatable muscles. SpongeBob purchases Anchor Arms, and then goes to the Goo Lagoon bar to show off his (fake) muscles. When Sandy sees him, she enrolls him in the Anchor Toss Competition, where each contestant must throw an anchor the farthest they can. SpongeBob cannot even lift the anchor, and blows up his Anchor Arms so much that they explode, revealing him as a fraud. The next scene shows SpongeBob changing TV channels with a remote in Sandy's treedome as an to get stronger exercise, which he finds exhausting.
