高強度间歇性锻练（High Intensity Interval Training, HIIT):
热身15分钟。极速跑或蹬自行车30秒，然后慢走或慢骑车3分钟。重复5-6次。最后10分钟慢走，结束。此类锻练有助于线粒体新生及功能恢复。
Interval Exercise:
Warm up for 15 minutes, adding a few 20-second bursts at the end to prepare for the workout. Run, bike, or row for 30 seconds at a nearly all-out effort. Take three minutes active recovery and repeat the 30 on/3 off pattern five or six more times. Finish with a 10-minute cooldown.
