Hello Kaden Van Buren,
Thank you for your question.
No growth stunting will occur; but, please, as the others suggest, do be careful and find someone to help you learn proper technique with the correct amount of resistance used for each body part. You want to be balanced and injury free while letting the body do its thing to continue growing.
I am glad to hear you are interested in taking care of your health; good for you. I joined the weight lifting club in school at your age with a coach supervising us at all times. This proved very helpful and enjoyable for me; I hope you are able to do something similar.
Best of health to you,
Mrs. Natalie Smith aka NAPS 2 B Fit.
No – you’ll be fine. It’s a great age to start strength training. I just started training my 13 year old daughter who plays volleyball and softball. However, as others have pointed out, it’s very important that you learn how to do all the exercises correctly. Start out light and don’t worry about how much weight you’re using – concentrate on using good form. If you don’t, you probably will end up getting hurt so let’s not do that.
The strength gains will come but you need to be patient. Also, you’ll need the help of a personal trainer or a Phys. Ed. teacher at school to make up a workout plan and supervise you to make sure you’re doing the exercises right – that’s important. Using dumbbells are fine & body weight exercises are great too. You’ll probably need different weights for different exercises – some muscles are stronger than others. Start by getting help from a qualified trainer or ask at school – I’m not crazy about a few of those exercises you mentioned – especially wrist lifts. Good luck Kaden & have fun with it – that was the age I started! Check back & let us know how you’re doing.
While this should not be a problem, it could be if you are using poor mechanics (moving without good control) and poor acceleration/deceleration (moveing too fast).
I would recommend trying to find weight training classes at your local rec center, YMCA, or find a fitness instructor to teach you about weight training. It is time well spent. While you may have some friends that are lifting together, it isn’t wise to follow the lead of someone that hasn’t learned all the do’s and don’ts of weight training.
