Chapter 10

Chest Press Machine is the tenth chapter of the manga Dumbbell Nan-Kilo Moteru?

Summary
Hibiki and Akemi are at the gym but the gym is full which surprises Hibiki. Machio explains to Hibiki and Akemi that all gyms have peak hours were specific groups of people will usually be at the gym. However, during the holidays, this becomes non-standard and everyone comes to the gym at roughly the same time.

The Silverman Gym's core times during holidays (as well as many other gyms):
 * Between opening hours to 13:00 is the core time for elderly people and adults during days off.
 * From 13:00 til about 15:00 is the core time for students/housewives.
 * From 19:00 til 21:00 is the core time for adults after work.

In the holidays, the most crowded time is near lunch time between 12:30 to 13:00. This is called the super core time.

As the gym is packed, Machio suggests working out out using the weight machines, to which Akemi says "MACHINES ARE HERESY!" as lots of people think this way. However Machio comments that weight machines have their own charm as you can focus on specific muscles without using stabilizing muscles. Machio introduces the girls to the chest press machine, since the chest press machine is more efficient at putting stress on only the chest. Machio recommended to use both free weights and weight machine depending on your goal. Akemi is surprised on how good the chest press machine is.

While this is happening, the gym clears out. Ayaka then shows up, revealing she now teaches boxing classes at Silverman Gym, as her gym is too crowded. Satomi is shocked to see another of her students at the gym.

Exercise Learned
The exercise machine focused on in this chapter is the chest press machine, which allows for isolated exercise of only the chest muscles.
