It is normal for the strength of intermittent practice to decline, and fitness needs to be adhered to. If you don't do it for a few months, the decline will be obvious; However, if your strength level is high, even if it drops, it will not be too big and it will be easy to recover. High school exercises every week, bench press 85 kilograms, and I have been in college for two years, so I haven't practiced again if I have no conditions. Once in a while, 60 kilograms is still very easy, but it can't hit the maximum weight. It is normal to feel muscle weakness after exercise. Because high-load exercise consumes glycogen stored in muscles, without this reserve, you can't be guaranteed to engage in sports activities for a long time. The best way is to replenish energy after exercise, such as eating protein powder with glucose, or eating bananas, so that the proportion of sugar absorption is faster. At the same time, eat well at dinner, ensure energy supply and pay attention to rest.
