Poor fitness can negatively affect you, both physically and emotionally. You need to do a lot of your research so that you don't seriously harm yourself working out. There are some tips listed below to help you start with a fitness regimen that can work for you and your goals.
In order to maximize your fitness routine, be sure to keep your workouts under an hour. This will help to prevent injury, as well as get the most out of your workout. You can actually lose muscle and testosterone because your body goes into a minor state of shock due to release of a chemical called cortisol.
To get the most benefit out of your strength training, incorporate stretches into your routine.
