Have a special event or beach day that you want to look more defined for? Learn the basics of water retention. Start the week off with more water than normal and each day drop your water intake, so that by the last day you are just drinking sips. This method helps drain the subcutaneous water that lies between your skin and your muscles. Also make sure to watch your sodium intake too because it makes you retain water and feel bloated! (from model Anthony Barillo)
