Strength training(力量训练), a type of exercise, is used to(被用来) build strength and power. Many adults(成年人) do strength training, but is it safe and useful for children? People once thought it was useless and even dangerous. However, the latest study shows that strength training does improve children’s health.
When children do strength training, they get stronger as their muscles(肌肉) grow. “It is so good for their bodies, like their metabolic(新陈代谢的) health,” says Becca Rigg, a trainer at a fitness centre. She takes her kids to strength workouts two to three times a week.
“I also love the message teenagers receive when exercising this way. They may feel more confident when they finish such hard and tiring training. They are getting stronger while having a better image,” explains Rigg.
How do kids get started? Just like other activities, it is very important to learn the right way to do it. For strength training, it is a must to learn from an experienced coach because the coach can make sure children do movements(活动) safely and correctly. In the early time, it is best for teens to simply use their body weight, such as doing push-ups, planks and squats. Body weight movements can then be made more difficult by adding equipment(增加装备) or weights, for example, a barbell or dumbbells.
So, let’s cheer our kids on as they lift, pull and push their way to a stronger future. With our support(支持) and care, they’ll grow up ready to take on whatever life throws at them.
