背景技术Background technique
在生活中，健身运动已经成为人们减肥塑形、增强体质的热门方式之一。健身运动有很多种，例如骑行、举哑铃、臂力器等。正确的健身方式能够增强体质，但是如果错误地健身，就会得到反效果。在现实中，大多数人因为缺乏专业的健身知识，也没有专业人士的指导，所以很容易就会在健身运动时没有按照正确的姿势进行，长久下来，就会养成了错误的健身姿势。错误的健身姿势会造成腰椎、肌肉等的问题。In life, fitness exercise has become one of the popular ways for people to lose weight, shape their body and enhance their physique. There are many kinds of fitness exercises, such as cycling, lifting dumbbells, arm strength machines, etc. The right way of exercising can strengthen your body, but if you do it wrong, it will have the opposite effect.
