After a good workout, you should feel spectacular. Your spirits should be lifted and you shouldn t feel any anxiety. Little should bother you because your body has a surge in endorphins after training. You should feel strong and energetic from one set to the next. If you start training and your energy level plummets, you probably are using too much weight, you may be rushing through your sets, or you may not have eaten enough before going to the gym.
Lactic acid is present after working a muscle, producing natural growth hormone.
Studies show that natural growth hormones will help your muscles grow and make your fat cells shrink. Basically, each time you work out, you re making microscopic tears in your muscles. When this happens, it means you ve exhausted the muscle, and it will likely grow back bigger and stronger with proper rest. Perhaps you can t wait to get out of the gym. If training bores you, you re probably not doing enough exercises, your body isn t releasing endorphins, and you re likely getting bored.
