Do you know these fitness knowledge?

I have introduced a lot of fitness knowledge before. Today we take a look at some other little knowledge.
1. How about breathing during exercise?
When we are doing weight training, we are often short of breath, and some people may even feel dizzy. These are caused by the lack of oxygen in our body.
I think that when doing heavier movements, in order to better exert force, I will hold my breath. It is an instinctive reaction of the body, which can increase strength in an instant.
But then, it's not a set of actions! How to do the next few? Therefore, when we put down the equipment, the muscles are in a stretched state, relatively relaxed, and we will inhale. And when our muscles are tight, we will exhale suddenly.
2. Why drink more water?
Water accounts for 50% to 60% of our body weight. It can be seen how important drinking water is. We sweat a lot during fitness, so we need to replenish water even more.
If the hydration is not timely and insufficient, it is easy to cause dehydration. The most obvious manifestation is that you suddenly feel that you do not want to train during training. This is the manifestation of the body's lack of water.
In addition, if students want to build muscle, consuming a lot of water can help us absorb protein. Studies have shown that when we consume a lot of protein, our body needs to consume a lot of water.
3. How should I eat a cheat meal?
Let's take a look at the purpose of eating fraudulent meals-keeping a high-protein, low-carb diet for a long time, the body's metabolism will decline. And eating foods like cheat meals can make our body think that we are okay and work more seriously. When will our metabolism decline and we need to eat cheat meals? When eating low-calorie foods, we will not feel hungry, which shows that your body is adapting to low-calorie foods at this time. At this time, cheat meals should be eaten to cancel the body's adaptation to low calories. Only then can it re-rotate.
