Plot

Goofy tries to get fit using home gym equipment, leading to a series of comedic mishaps. His clumsy efforts and the malfunctioning gear result in slapstick accidents, highlighting the humor in his unpredictable fitness journey.

Inspired by a magazine ad, Goofy sends for a mail order body building course. First is weight lifting; after Goofy finally gets the weights up, a fly lands and sends him crashing through several floors in the apartment building. Chinups: the bar itself goes up and down. Then a rubber-band stretch device, which Goofy quickly tangles up in, sending him crashing through the building and several other pieces of equipment.—Jon Reeves <jreeves@imdb.com>

Goofy comes home from work exhausted, so he decides to keep himself fit by working out and doing gymnastics with hilarious results.

Goofy orders a home gym set and sends away for it. The package containing his gym set immediately arrives. After setting up the gym equipment in his home, Goofy dons his new workout suit which resembles a caveman lioncloth. Goofy compares himself to a chart depicting a man with a muscular development and realizes his own body does not match the chart. Determined to build his musculature, Goofy plays the record for his gymnastic program which instructs him to start exercising by lifting the barbells.

At his first attempt to lift the barbells, Goofy inadvertently stands on the bars while struggling to lift weights. Then the barbells clasp with the bar landing on his hands. Goofy yet manages to quickly fix the barbells, and then attempt to lift from behind his back which causes him to fall forward. With the barbells over him on the floor, Goofy tries lifitng them with his feet, only to have the weights close in on his hands and feet like two magnets. With his hands and feet trapped in the barbells, Goofy finds himself no choice but to lift up his rear end and move it back and forth as another attemt to lift the weight high. As a result, Goofy rolls himself forward and starts rolling on the barbells like wheels. To make matters worse, his workout suit falls over his head leaving his underwear fully exposed. Goofy shakes the suit off his head before rolling onto a board formed like a ramp. As Goofy falls over the board, the board briefly smacks his rear end, causing him to flip. This not only frees his hands and feet from the barbells, but also causes him to land on his feet with the barbells finally lifted over his head. Unfortunately, a fly lands on the barbells and adds Goofy more weight to lift. Goofy crashes through the floor and down several stories.

Goofy returns to his apartment exhausted as he was before. He compares himself to the muscle chart again, only to have it roll him up it, and then drop him back to the floor.

The next exercise is the "chin lift." While Goofy appears to be lifting his chin over the bar, his feet actually never leave the ground for the bar he grips is just sliding up and down on the poles supporting it. When Goofy is finished with that, the bar slides down on his head, forming a bump. Goofy pushes the bump down inside himself and forms it on his arm making himself believe he has built a muscle.

Finally, Goofy works on stretching a cable stretcher. In the process, Goofy gets tangled in the cable. As he opens the cable like a spider web to escape from it, the cable traps him again and yanks his workout suit off. Goofy crawls inside his suit, and thenstretches the cable with his feet, only to fling himself across the room.

While flying across the room, Goofy grabs onto a set of lifting rings and swings back and forth until he repetitively crashes through the walls. He falls out a window in the ceiling, flipping in the atmosphere outside the building, and then falls back into his apartment through another window. He falls in stretching on another cable and dribbles on his bottom like a basket ball until he reaches his mirror. As the cable pulls him back, his reflection comes to life and waves to him. The chaos continues as Goofy runs into his equipment that sends his flying across the room until he falls through a window. His foot hooks onto a ring suspended by a cable on the ceiling. Goofy flies out of the building again, across a street, and above several stories with the stretching behind. Goofy grabs the edge of a window, frightening a woman who lives in that apartment and prompting her to strike his hand with her high-heel shoe. Goofy gets dragged by the cable back into his apartment. As he crashes through the wall. he accidentally breaks the muscle chart out of the wall, making it appear that he has finally built his full musculature. Then Goofy falls asleep.
