If your goal is to improve your health and reduce your risk of a range of conditions from diabetes to heart disease to cancer, then 2.5 to 3 hours of moderate to vigorous exercise per week gets you the vast majority of benefits, Dr. Levine said. “Once you get past five hours per week or so, you’re not exercising for health, you’re exercising for performance.”
网络上一直说每天锻炼30分钟到60分钟就最好。
问题：超过一小时是不是没有必要， 或者是浪费时间？（把运动当追求，爱好的另当别论）
（我每天1小时跑步,另外3天 gym, 3天游泳，目的是健身，有时会有这疑问）
还举哑铃，仰卧起坐
10英里就是16公里啊，走路得快三个小时了吧，再加上别的，得接近4个小时？
