Earlier than you think . . .
Let me first emphasize that I am speaking about strength training and not traditional weightlifting. In which the primary goal of traditional weighting is to push or pull “heavy” resistance via weights, to and from the body with the common purpose of building muscle size. Traditional weightlifting in a young person’s body can strain muscles, tendons, and ligaments too much. And can lead to serious injury.
Strength training for young children can simply involve body-weight exercises like push-ups, sit-ups, body squats, and the use of resistance bands or light free weights. Proper form and technique are key when resistance training. Recruiting the help of properly trained Fitness Instructors is the best way to implement strength training for youths.
Young children do not have to be involved in organized sports to partake in strength training. Strength training for any youth can help strengthen bones and build confidence, not to mention build overall good health. But as always when taking on any new health endeavors—at any age, consult with your physician for a full evaluation of your health and physical status.
Many health and exercise professionals believe starting a strength training regimen for kids, can begin as early as 7-8 years of age. Make sure to have a conversation with your children on the importance of following instructions, and applying proper techniques when performing strength exercises. And that goofing around during training exercises can lead to injury, even if you are just performing body-weight exercises. With this safety focus in mind, it is also equally important for the child to have fun. Make the whole workout experience memorable for years to come.
