Does Weight Training Stunt A Child's Growth?

Strength training, a popular form of exercise aimed at enhancing muscle strength and endurance, has raised concerns, especially regarding its impact on youths. Among the various concerns, a prevalent myth persists: does strength training hinder a child's growth? This question has left parents, coaches, and young athletes seeking clarification. In this article, we will address this enduring belief, discerning reality from misconception to offer a comprehensive understanding of how strength training intersects with growth during pivotal developmental stages. Let's delve into the scientific inquiry behind this myth and unveil the truth.

Childhood growth and development

As parents, you need to understand the different stages of childhood growth to ensure they receive the appropriate care and support to thrive.


This is the first stage of childhood growth, which typically lasts from birth to 12 months. At this time, your infants experience rapid growth in their height, weight, and head circumference. They also develop gross motor skills, such as rolling, crawling, and walking. It is essential to provide them with proper nutrition, like breast milk or formula, to support their growth and development.

Early Childhood:

The early childhood stage, which encompasses the period from 1 to 3 years of age, is a critical phase in your child's development. During this time, children undergo remarkable physical and cognitive growth. Properly nourishing them, encouraging physical activity, and introducing early education play pivotal roles in fostering their healthy development.

Middle Childhood:

The middle childhood phase, spanning from ages 6 to 12, marks a period of gradual and consistent growth in terms of both height and weight. Additionally, children in this stage acquire more advanced cognitive abilities, such as problem-solving and critical thinking. Therefore, it is essential to prioritize the provision of adequate nutrition, opportunities for physical activity, and supportive social interactions to nurture their development.


The final stage of adolescence, spanning from 12 to 18 years, is a transformative period for all children. During this time, they undergo significant growth spurts, particularly in terms of height and muscle mass. Furthermore, adolescents develop more sophisticated cognitive skills, including abstract thinking and decision-making. This stage is pivotal in shaping their future, making it imperative to provide them with the necessary resources and support to navigate this critical phase successfully.



Debunking the myth: Does weight training stunt a child’s growth?

Firstly, you need to know that weight training does not directly affect a child’s height. This is because height is primarily determined by genetics and nutrition. However, this might affect their growth in terms of muscle development and bone density.

When a child engages in weight training, they are putting stress on their muscles, which in turn stimulates the growth and development of these muscles. This can lead to an increase in muscle mass and strength. Engaging in weight training also gives a positive impact on bone density, which is crucial for overall bone health and reducing the risk of fractures [1].

So, should kids practice weight training? Does it hinder their growth?

The short answer is no. However, there are some important considerations to keep in mind.

Weight training should always be supervised by a qualified trainer or coach to ensure proper technique and safety. Your children need to use suitable weights for their age and focus on suitable forms and techniques. If they have certain medical conditions or physical limitations, you should consult with a healthcare professional before beginning any exercise program.

Benefits of weight training in children

While weight training for children is still somewhat controversial, there are many benefits to starting a weight training program for your child.

Develop stronger bones and muscles

When children practice weight training exercises, their muscles are put under stress, which triggers the process of muscle hypertrophy, or the increase in muscle size and strength. This leads to an improvement in muscular endurance, power, and overall physical performance.

Additionally, this training has been shown to increase bone density, which is crucial for the prevention of osteoporosis later in life.

Improve coordination and balance

Strengthening the muscles used for specific movements in any weight-training exercise improves your kids’ coordination. Moreover, it can help them develop body awareness and control. Relying on that, they can better control their movements through consistent training, boosting their coordination and balance in everyday activities.

Develop self-esteem and body confidence

As children see improvements in their strength and physical abilities, they are likely to feel more confident and capable in other areas of their life as well. By practicing weight training, they also learn about setting and achieving goals, which can help them feel more empowered and in control of their own lives.

Furthermore, if they become stronger and fitter, they may begin to appreciate and value their bodies for what they can do rather than solely for how they look. This can be especially beneficial for those who struggle with their body image issues or have been exposed to unrealistic beauty standards through media and society.



Tips for starting a weight training program for children

Although this exercise can provide numerous benefits, it is important to approach it with caution.

Make sure your kids are physically ready

Children who are overweight, have a history of joint problems or injuries, or have not yet reached puberty may not be ready for weight training. You should consult with a healthcare provider to determine if practicing this exercise is appropriate for them.

Find a qualified trainer or coach

Your chosen trainer needs to have a background in exercise science and be certified by a reputable organization, such as the National Strength and Conditioning Association or the American Council on Exercise. They should be knowledgeable about child development and have experience adapting exercises to meet the needs of young athletes as well.

Focus on proper form and technique

Children should start with light weights and gradually increase their weight as they become stronger and more comfortable with the exercises. The program should also include different exercises that target various muscle groups and incorporate both upper and lower body movements.

Also, they need to join other forms of physical activity, including cardiovascular exercise and stretching. This will help them develop a well-rounded fitness routine and reduce the risk of injury.

Set realistic goals

Setting small, achievable goals can help build confidence and momentum. For example, starting with a goal to do one more rep on an exercise each week can lead to bigger improvements over time. Avoid planning goals that are too lofty, or this results in frustration and disappointment

And do not forget to celebrate each small victory along the way toward the larger aim. This can help keep your child motivated and encouraged to continue their weight training journey.

In conclusion,

Weight training does not stunt a child's growth if done properly with appropriate guidance and supervision.

In fact, it can provide numerous benefits for their physical and mental development, including improved muscle and bone strength, coordination and balance, and self-esteem. It is important to ensure their program is age-appropriate and tailored to their individual needs and goals.

By setting suitable goals and gradually increasing the intensity and duration of the training, your children can safely and effectively engage in this exercise to enhance their overall health and well-being.

Finally, remember that weight training should be fun for children. Creating a safe and positive environment can help them develop a lifelong love of fitness and healthy living.
