How much weights should a 12 years old pick up?

The amount of weight a 12-year-old should lift depends on their individual strength, fitness level, and experience with weight training. Generally, it's recommended that pre-teens focus on proper form and technique rather than lifting heavy weights. Light resistance, such as bodyweight exercises or light dumbbells (5-10 pounds), is often appropriate. It's also advisable for young teens to consult with a coach or physical education instructor to ensure safety and proper guidance.
