The body tends to adapt to a given stimulus given enough time and support. If you give your body a week to recover, it will tend to be "lazy". If you make it recover in 2 days, it will recover faster assuming you give it time and support to adapt. Muscles can recover pretty quickly.
However I have to emphasize your given work tolerance and gradually increasing volume and frequency in order to give your body the chance to adapt. If you jump into full body 4 times a week from once a week, you may likely get trashed and overtrain. However do it gradually over months and you should be okay given proper nutrition, rest, and lifestyle.
