健身力量练习图解
1Russian twist
Do this with a medicine ball or other weight between 3–10kg. Sit on the ground with your feet on the floor. Rotate the hips to either side, alternating left and right with a fluid, controlled movement without stopping in the middle.
Caution: Anyone with a back problem shouldn't do this exercise.
Routine: 10 reps per side. As you progress, try the same routine with your feet lifted off the floor Photograph: Jamie Baker/Jamie Baker  
俄罗斯转体练习
该动作使用的是实心球或其它重量器械,重量在3–10kg之间。练习者坐于地面,两脚着地。向身侧做转髋练习,左右转换时,动作要连贯,控制好动作。练习时,中途不能停顿。
注意:背部有问题的人不宜做此练习。
练习方法:每侧10次。随着练习的一步步适应,可以尝试将脚抬离地面做同样的练习。Photograph: Jamie Baker/Jamie Baker 
2Hamstring stretch
This is a key stretch because in most people the hamstrings have a tendency to tighten . Rest one bent knee on a mat with the other leg extended straight and locked in front of you - the idea is you lean forward and so stretch the back of the leg but most people can get a stretch in the basic position.
Routine: Hold for 20–40 seconds, then repeat on the other side. Try three sets on each side Photograph: Jamie Baker/Jamie Baker 

2腘绳肌拉伸练习
这是一个重要的拉伸练习,大多数人的腘绳肌(该肌包括包括半腱肌、半膜肌、股二头肌长头、大收肌坐骨部)比较紧。本练习在练习时,一腿曲膝,跪撑于垫,另一条腿伸直,控制于体前方——此练习的目的在于向前压腿,拉伸腿的后部。对大多数人而言,他们只需完成基本的拉伸动作。
练习方法:拉伸的时间保持20-40秒,然后另一侧腿重复同样的练习。每侧腿分别练习3组。Photograph: Jamie Baker/Jamie Baker
