Don’t forget your water!
Remember that you need to drink half of your body weight in ounces of water daily. If you are working outside or sweet profusely, you will need to increase your consumption beyond this. It takes about 24 ounces of water to rehydrate you if you are dehydrated by 8 ounces. For this reason it is much more efficient to prehydrate for a workout than to try to rehydrate after it. To prehydrate, drink a minimum of 1 liter before/during your workout. It may be beneficial to drink another liter immediately following your workout.
