I build the craziest working leg extension by LEGO, MUST SEE🔥🔥! + Hidden Yoda! #lego #gym #yoda #moc

This build took me around three days to complete. The hardest part was designing the mechanism that turns a continuous rotation into a back-and-forth movement — and making it last long enough instead of just spinning quickly. I had so much fun creating all the small details, especially the gym figure and its facial expression! But... did you spot the secret Yoda figure pumping?
