茶: 说到测心跳,正好有问题。
我们积木的走步机,双手握上去可测心跳。问题是在我快走的时候,测出的心跳只有七十多,如果马上慢下来,才能测出100以上的心跳。为什么?我不可 Some treadmills can not detect heart beat accurately when the speed is too high. You can try to put hands back again and sometimes it would work.
The reason you do not feel sore is your muscles are used to the moves. That is why you do the classes alternatively --- not do the same class in a consecutive way. It still works, but not as effective. |
