"Create a close-up, humorous scene of a determined hamster working out by lifting tiny weights made from walnuts. The hamster grips the 'weights' with its little paws, lifting with an intense, focused expression as if in a serious gym session. The background should resemble a miniature workout area, complete with small gym props, like a water bottle cap as a 'hydration station.' The setting is cozy, earthy, and detailed to make the scene feel like a realistic hamster-sized gym. Capture the hamster's adorable determination and strength, as if it's training hard for a big competition.
