Create an image of a muscular cat with a slightly cartoonish, semi-realistic style. The cat should be holding either a barbell, a dumbbell, or wearing boxing gloves, showcasing its strength and sporty nature.

The overall design should balance between realism and a hint of cuteness, avoiding too much exaggeration."
