'Shrink'.
Arthur felt himself giving off an ominous pink glow. He feels a tingling sensation where the beam hits him but nothing happened.
"Hm, nothing." He sighed.
He put the gun in his cupboard, and then changed into his gym clothes and started doing deadlifts.
But little did he know was that his shrinking was working.
He was gradually getting smaller, bit by bit.
After a few reps, he noticed the weights felt heavier, so he changed them from 60kg to 50kg. After a while, even they felt too heavy. Then he set them to 40kg, but soon, even that was too heavy, even for him.
he almost seemed to be getting weaker.
Also, when he sat up on the bench, he saw his gym clothes were starting to feel looser on his body.
He almost seemed to be losing weight.
"Whew." Arthur said. "I've never felt this tired before." he decided to stop for a while, to get his breath back.
"Huh." he said, eying the gym equipment. "I never knew my gym equipment was this large."
