Exercise Stage

This stage should last for a minimum of 12 minutes though most people start at about 15\~20 minutes. After repeat it easily for several times, you can increase training strength. After exercising for a period of time, your heart beat will be close to the best position in the graph as below (Shaded part). Note: This exercising is for your whole life, it cannot complete in one night, so you should keep it.

Recovery Phase

This stage is to let your Cardio-vascular System and muscles wind down. This is a repeat of the warm up exercise e.g., reduce your tempo, continue for approximately 5 minutes. Then repeat the exercise phase, please be careful not to force or jerk your muscles.

When using elliptical fitness exercises, please don't increase training intensity arbitrarily. It may make your leg muscles sprain, which means you can't continue exercising for a long time.

Equipment Tip
