Chapter 89

Jump Rope is the eighty-ninth chapter of the manga Dumbbell Nan-Kilo Moteru?.

Plot
The day of Silverman Gym's hosted event: the Body Fat Reduction Contest has arrived Ayaka, Akemi and Gina arrive on the beach it's held at, hoping to support Hibiki and Tachibana-sensei for their chance at winning the prize! Did their teamwork pay off? Did either win the top prize!?

But it's not just about the girls in their bikini outfits, no! There's all sorts of food stands to visit and games to play! Machio, Jason and Tadakatsu are all here, too, fulfilling the role of masters of ceremony! Let's find out what clear goals and strong effort brings to a gym-goer!

Exercise Learned
The exercise focused on in this chapter is jump rope which is a form of calisthenics performed by hopping in place while spinning a rope around your body. Generally thought of as a children's game, given its accessibility and ease-of-understanding, it's actually a particularly effective means of cardiovascular exercise and fat-burning!

Trivia

 * After Gina and Ayaka pose mocking faces behind Satomi's back, Akemi refers to them as the "Rokudenashi Danberus." This is a reference to the Rokudenashi Blues, as the famous face made is directly pulled from that manga series.
 * As Hibiki gains enormous weight on the final page, she takes on the appearance, and the sound effects of, Jabba the Hutt from Star Wars; known for his obesity, overeating, and slug-like appearance.
