Rest and recovery is an important part of any workout routine and is equally important to your fitness gains and sports performance as the workout itself, also it allows you to train much more effectively. The recovery after any exercise routine are essential to your body’s muscle and tissue repair and strength building. This is even more critical after a heavy weight training session. It is said that a muscle needs anywhere from 24 to 48 hours to repair and rebuild, and working it again too soon simply leads to tissue breakdown instead of building. But bear in mind that for weight training routines, you need to rest the muscle group you exercise for at least a week before training it again. The recovery process is as essential as the workout itself.
