Certain training, especially strength training, can increase bone density, stimulate bone growth, make muscles grow, improve the overall physical quality, and be beneficial to the physical development of teenagers.

Although strength training such as barbell squat has many benefits for the growth and development of teenagers, it is still not recommended to carry out weight-bearing training without professional guidance for the following reasons:

Minors' bones are softer than those of adults. If heavy training is carried out, it will easily lead to skeletal deformity, leading to posture problems such as pelvic forward tilt and scoliosis.

Without professional guidance, teenagers have a great misunderstanding about the mastery of strength training techniques or just subjectively judge the correctness of actions, which brings great harm and high risk of injury. Therefore, it is not recommended to carry out weight-bearing strength training, especially for middle and high weight-bearing people.

There is no great need for teenagers to carry out heavy-load training. Teenagers' bodies are in a high-speed development stage, and unarmed self-weight training is enough to stimulate the body. In addition to self-weight strength training with bare hands, outdoor sports such as basketball and football can also greatly improve physical fitness.

Therefore, teenagers can do strength training such as squats, but without professional guidance, weight training, especially heavy weight training, is not recommended. At this time, you can start to learn the correct posture, experience the feeling of exerting strength with your own weight or very light weight, understand the basic knowledge of fitness, and make knowledge reserves for future sports.
