First of all, any exercise is better than sitting all day. Any exercise counts as a “good” workout. So, you’re already way ahead of the game, six-pack or not! With that said, you might experience unusual things if you’re new to exercising, trying a new exercise, or increased the intensity.
Remember, don’t think that since you didn’t have any of these signs, your workout wasn’t “good”. Everyone’s body reacts differently to exercise, so don’t sweat it. The following signs don’t have to be so intense either.
Not so fast! The bigger appetite can be blamed on skipping a pre-workout meal, or your body simply burned a lot of glycogen stores. In brief, glycogen stores are carbohydrates. When too much glycogen is used, the body resorts to taking sugar out of your blood to use as energy.
Since you have little sugar left, the hunger hormone ghrelin is released. This hormone is released to signal your brain that more sugar is needed. That’s why it’s important to eat before and after exercise, as low blood sugar can cause seizures and dizziness to occur. Some good foods to eat before or after a workout is oatmeal.1 2
There’s a list of possibilities as to why you’re tired after exercising. You might be dehydrated or not have eaten enough before or after exercise. However, if you did drink water and ate, then it’s probably because of your muscles. You see, as you exercise, your muscles get torn up. Then at night, when you sleep, your muscles recover. For this reason, that’s why it’s advised to avoid exercise if you couldn’t sleep at night. 3
Just like all the other signs, sore muscles can be good or bad. If you find that you can’t perform daily activities because it’s too painful, you probably went too hard. Also your muscles shouldn’t feel sore right after your workout, but usually the next day.
The soreness is called DOMS, or delayed onset muscle soreness. The pain comes from muscles tearing and growing. To ease the pain, try light exercises, such as walking or a gentle stretch. 4
Everyone could use more energy throughout their day. Luckily, this is where exercise comes in. Before anything else, your muscles need nutrients and oxygen as fuel, which are found in your blood. The chemical, adenosine, is used to improve your blood flow to muscles. Since your body will produce more adenosine, you’ll have more energy as a result. 5
