Frequency: How Much is too Much?
During exercise you're creating tiny (micro) tears in muscles fibers. Then during the recovery phase the muscle regenerates stronger and firmer. This is why the RECOVERY portion is SO important without proper rest, your body can go into what is called over-training a negative state in which no gains are seen and the risk of injury is high.
"When you work out you're not building you're breaking down muscle tissue."
Vigorous physical training places a high energy demand and stress on the body.
You may think if some exercise is good more must be better. Nothing could be further from the truth. In fact less can be more.
Everyone's body is different as far as the amount of time that's needed for recovery from exercise. As a rule of thumb you want between 48-72 hours of rest between training specific muscle groups. You'll want at least one day of recovery between muscle groups.
Even elite athletes take at least one day a week to rest and recover! Does that mean you have to lay around and do nothing? NO, But keep it light walking, gentle yoga or stretching, is enough!
REST FULLY AND COME BACK STRONGER!
