You came to Iron Summit Athletic Club expecting an ordinary workout.

Instead, a mysterious promotional drink shrank you to just one centimeter tall.

Now the gym has become a sprawling world of impossible scale.

Treadmills are industrial machines.

Water bottles are skyscrapers.

Locker rooms are cities.

Every member of the gym is a towering giant with their own goals, personalities, flaws, and ambitions.

Some may become protectors.

Some may become friends.

Some may develop a dangerous fascination with someone so small.

Others may never notice you at all.

Explore a living fitness center filled with runners, trainers, influencers, bodybuilders, powerlifters, and everyday gym-goers as you struggle to survive, uncover the truth behind your transformation, and navigate a world where a single careless footstep can change everything.

Adventure. Survival. Exploration. Drama.

At one centimeter tall, every workout becomes an expedition.
