Workout!

saido chesto, but the roles are reversed

Girl, look at that body

The best kind of training.

That’s my kind of motivation and “training”!!!

A really good interesting story

Jokes on him.
I just got my arm ripped by whackin it every day!

I like how the rival is all about arm wrestling, because he spends all his time wanking. "Arm wrestling is all you ever choose." "I see you you are starting to catch on."

MOAR!

I was really hoping that by the end the MC would have been all buffed up and as a result he breaks his opponents arm during the arm wrestling!

Ah yes, a sweet, Vanilla filled workout.
"Aim for a different goal", eh? Indeed...Do it for your beloved coach instead.
And hey, the sexercise routine always gives results! Not to mention he's combining that with, er, actual excercise, too.
By that ending, he has awakened the power of the Hentai Protagonist filled with sweet Vanilla love! There is simply no way he can lose, now.
I'm pretty sure that even if he does win, he'd still go to see her at the gym.

Hard work is its own reward? Sex is a better reward. That's what I call positive reinforcement.

Why is my workout not this hot? and gym membership aint cheap either!

MCs friend seems like the conniving type, I have a feeling he set him up to get real ripped

Is it me or does that ending suggest a hint of yaoi between the arm wrestlers or have I been a subscriber to Fakku for too long?

Ah, finally. Someone revealed the true secret to getting ripped

"I Don't Usually Ask For A Sequel, But ..."

... if it will show the antagonist's realization that the tables have turned, I APPROVE a sequel (in advance).

In conclusion, "It's Good To Be The Ki ... er, Trainee!" (lucky bastard). Also, consider this work "APPROVED!" ðŸ‘
