Radical
Muscles

Mnemonic

What gives you muscles? Power, power, and more power! Three doses of raw power stacked on top of each other—one for your arms, one for your legs, one for your core. That triple power is what builds muscles so massive they rip through your sleeves.
Additional thoughts
Three 力 (power) radicals stacked vertically form this kanji. Visualize three bursts of power surging through different muscle groups, compounding into one hulking physique.
Quick recall
Triple power—arms, legs, core—builds unstoppable muscles.
