SleepingTo achieve maximum results on any exercise program, there must be a balance between the following three variables:

• A training program of progressive overload

• Nutrition to energize the body and build and repair new tissue

• Enough good quality rest and sleep to allow the recovery of the body to take place.

Because over training happens primarily to insufficient rest, it is recommended that we sleep approximately 7-9 hours a night. Lack of sleep can cause a suppression to immune system, which leaves the individual susceptible to illness, injury, and infection.
