Is Strength Training Okay for Kids? Should Children Lift Weights? Is it SAFE?

Q: Is Strength Training Okay for kids?

Strength training offers kids many benefits, but there are important caveats to keep in mind. Here's what you need to know about youth strength training.

By Mayo Clinic staff Strength training for kids? You bet! Done properly, strength training offers many bonuses to young athletes. Strength training is even a good idea for kids who simply want to look and feel better. In fact, strength training can put your child on a lifetime path to better health and fitness.

IMPORTANT! Strength training, not Weight Lifting:

For kids, light resistance and controlled movements are best — with a special emphasis on proper technique and safety. Your child can do many strength training exercises with his or her own body weight or inexpensive resistance tubing. Free weights and machine weights are other options.

Don't confuse strength training with weightlifting, bodybuilding, or powerlifting. These activities are largely driven by competition, with participants vying to lift heavier weights or build bigger muscles than those of other athletes. This can put too much strain on young muscles, tendons and areas of cartilage that haven't yet turned to bone (growth plates) — especially when proper technique is sacrificed in favor of lifting larger amounts of weight. 

For kids, what are the benefits of strength training?

Done properly, strength training can:
  • Increase your child's muscle strength and endurance
  • Help protect your child's muscles and joints from injury
  • Improve your child's performance in nearly any sport, from dancing and figure skating to football and soccer
And strength training isn't only for athletes. Even if your child isn't interested in sports, strength training can:
  • Strengthen your child's bones
  • Help promote healthy blood pressure and cholesterol levels
  • Boost your child's metabolism
  • Help your child maintain a healthy weight
  • Improve your child's self-esteem

When can a child begin strength training?

During childhood, kids improve their body awareness, control and balance through active play. As early as age 8, however, strength training can become a valuable part of an overall fitness plan — as long as the child is mature enough to follow directions and practice proper technique and form.

IMPORTANT! If your child expresses an interest in strength training, remind him or her that strength training is meant to increase muscle strength and endurance. Bulking up is something else entirely — and most safely done after puberty.

You might also check with your child's doctor for the OK to begin a strength training program, especially if your child has a known or suspected health problem — such as a heart condition, high blood pressure, or a seizure disorder.

What's the best way to start a strength training program for kids?

A child's strength training program isn't necessarily a scaled-down version of what an adult would do. Keep these general principles in mind:
  • Seek instruction. Start with a coach or personal trainer who has experience with youth strength training. The coach or trainer can create a safe, effective strength training program based on your child's age, size, skills and sports interests. Or enroll your child in a strength training class designed for kids.

  • Warm up and cool down. Encourage your child to begin each strength training session with five to 10 minutes of light aerobic activity, such as walking, jogging in place or jumping rope. This warms the muscles and helps reduce the risk of injury. Gentle stretching after each session is a good idea, too.

  • Keep it light. Kids can safely lift adult-size weights, as long as the weight is light enough. In most cases, one set of 12 to 15 repetitions is all it takes. The resistance doesn't have to come from weights, either. Resistance tubing and body-weight exercises, such as push-ups, can be just as effective.

  • Stress proper technique. Rather than focusing on the amount of weight your child lifts, stress proper form and technique during each exercise. Your child can gradually increase the resistance or number of repetitions as he or she gets older.

  • Supervise. Adult supervision is an important part of youth strength training. Don't let your child go it alone.

  • Rest between workouts. Make sure your child rests at least one full day between exercising each specific muscle group. Two or three strength training sessions a week are plenty.

  • Keep it fun. Help your child vary the routine to prevent boredom.
Results won't come overnight. But eventually, your child will notice a difference in muscle strength and endurance — which may fuel a fitness habit that lasts a lifetime. Priceless!

An Exercise to Strengthen your Cross Punch

Hey, I just found a great new TV Show called "Body Fuel". It's on the Canadian Network ION (here in Utah that's channel 16.3).

But it's awesome: Healthy workout-based recipes and an exercise of the day. Online, I'm afraid the workout is all you can get on video. But here's one that's new to me and is a great technique to strengthen your CROSS PUNCH or, in Karate, we call it the REVERSE PUNCH.

Anti-Aging: Exercise Unlocks Stem Cells in Muscles

Exercise Unlocks Stem Cells in Muscles
The combination of aging and a sedentary lifestyle significantly contributes to the development of diseases such as osteoporosis, obesity, diabetes and cardiovascular diseases, as well as a decline in cognitive abilities.

A common result of the aging process is sarcopenia, a decline in the mass and function of muscles. Dafna Benayahu, from Tel Aviv University (Israel), and colleagues studied a laboratory rat population, finding that endurance exercise increased the number of satellite cells (muscle stem cells), which normally decline with aging.

Comparing the performance of rats of different ages and sexes, they found that the number of satellite cells increased after rats ran on a treadmill for 20 minutes a day for a 13-week period. The younger rats showed a 20% to 35% increase in the average number of stem cells per muscle fiber retained -- and older rats benefited even more significantly, exhibiting a 33% to 47% increase in stem cells.

Further, the team found that endurance exercise improved the levels of "spontaneous locomotion,” a response mechanism that is typically reduced with aging. The researchers are hopeful that this finding leads to discoveries of new methods to raise satellite cell populations in human muscle tissue, to raise the production and performance of young and healthy muscles, to provide an anti-aging musculoskeletal benefit.
