It's generally recommended that children and adolescents wait until they've reached a certain level of physical maturity before starting structured gym workouts. This usually occurs around the age of 13 to 15 for most individuals, but it can vary depending on factors such as puberty and growth spurts.
Younger individuals who are interested in fitness can benefit from activities such as sports, dance, or recreational activities that promote physical activity and coordination.
It's crucial for individuals of any age to prioritize safety and injury prevention when engaging in physical activity, including gym workouts.
The decision to join the gym should also be based on individual goals, interests, and motivation. Some teenagers may be interested in strength training for sports performance, while others may want to improve overall fitness or body composition.
For younger individuals, it's important to have parental consent and support before joining a gym. Parents can help ensure that their child has access to safe and appropriate facilities, supervision, and guidance.
