So this is your chance! Youâre in recovery now and you have the opportunity to build the life youâve always wanted! 1  To get started, look in your heart and soul and find that thing that makes life worth living â and then build a long-term goal around it.  Once youâve got this, the rest is simply mechanics and sweat.
This will provide both fast-acting and sustainable energy to your body. Try to eat a snack within two hours of exercising, but wait a minimum of 15 minutes after exercising before you eat. Bring a snack along to the gym with you, so you can eat as soon as your workout is over.
You need to pay attention to certain things and learn how long to wait after eating to work out, but it is equally important to keep your body hydrated all the time. You need to drink plenty of fluids before, during and after your workout to stay hydrated. Drink about a 473-710 ml of water at least a couple of hours before your workout. Drink about 118-237ml of water after every 20 minutes during your training.
