1.Fat will be burn while exercise over 8 minutes.
2.Should exercise 20-30 minutes continuously.
3.Exercise to make heart rate 70% of maximum;Maximum heart rate easy way to know 220-your age; such as your age = 30 years old maximum heart rate about 220-30=190/minute.So optimal heart rate is about 130 time/minutes.Keep exercise 3 times/week is the best.
****Successful we will feel after one week.Then keep exercise to your target.Normally 6-8 weeks exercise we will get high performance;Feel free..Strong..Confidence.
