How much weights should a teen lift?

Answer 1

Assuming that your skeleton is ready for the stresses of weight training (which usually occurs around age 16, in my opinion), you should concentrate on the fundamental exercises (namely, squats, deadlifts, presses, rows, dips, and chins) just like everyone else who is beginning a serious weight-training program.

It is very important to learn and use perfect exercise technique right from the beginning. Avoid dangerous exercises. Avoid using weights that are so heavy that you get 4 or fewer reps (until you get older, in my opinion). Do injury prevention exercises (such as L-flyes and side bends). Instead of letting your ego drive you into rushing your development, think of yourself as laying the foundation for a lifetime of productive training. Perhaps the best book to get you started correctly is Stuart McRobert's BUILD MUSCLE LOSE FAT LOOK GREAT.
