Pure Nitro Max Rest is extremely important. During rest is the time that muscles are repairing and growing. When muscles are used they tear and therefore the body replaces that tear in your muscle cells with new thicker fibres from protein thus it grows. This process of repairing and building starts a couple of hours after exercise and can last up to a day. Thus you should rest the areas exercised at least one day, so that the process can be completed and the new fibres being place will not be broken right away.  http://guidemesupplements.com/pure-nitro-max/
