Episode 3

Sensei's on a Diet, Too? is the third episode of the Dumbbell Nan-Kilo Moteru? anime.

Prologue
The episode begins in the staff room, where history teacher Tachibana Satomi mentions to a fellow teacher that she’s gained a bit of weight. The other teacher can’t really tell but Satomi is adamant. She’s shown a flyer for the world famous Silverman Gym that’s recently opened up and is close to the school, but Satomi doesn’t want to run into any parents or teachers at the gym.

After visiting Silverman Gym, Satomi comes face-to-face with Hibiki and Akemi, where Akemi is eager for their teacher to join them in their workouts to become ‘macho’! Like Hibiki, Satomi decides that she won’t join the gym permanently and will just do the free trial (due to running into her students). However, like Hibiki, pays for a full membership once she meets Machio.

How to Perform a Bicep Curl

 * Relax your shoulders, feet about shoulder-width apart and let your shoulders relax.
 * Lift the dumbbell up towards your body, bending only at the elbow.
 * When you lift the dumbbell, make sure you don’t swing your elbows back and forth. “Cheating” with momentum reduces the stress on your biceps.
 * Add supination, i.e. rotations, to work your biceps more effectively.
 * When lowering the dumbbell, don’t completely extend your elbow.

Effects

 * Trains the biceps brachii.

How to Perform a Front Press

 * Hold the bar from above with an overhand grip.
 * Position it just above your collarbone.
 * Chest squared, elbows out front.
 * Don’t completely extend your elbows when lifting the bar.
 * Lower the bar and return to your original position.
 * Avoid bending your upper back or you might hurt your lower back!

Effects

 * Trains the shoulder muscles, in particular the deltoids.

Notes & Trivia

 * Efficient workouts and proper form, not weight, matter most in weight training.
 * At the convention, Machio cosplays as the Muscle King from the famous fictional series "Lifts with the Straight Bar". This is an obvious parody of the manga .
