It usually takes three or four days to practice regularly. Choose a day to have a full rest, and it must be a rest day. Otherwise, physical fitness can't keep up, and there will be a great sense of fatigue, which will affect the next training. When deciding the frequency of going to the gym, two things should be considered in the training plan: intensity, that is, the heaviest weight you lift, and the amount of training, that is, intensity × times × groups. Every time you change one of these factors, the other two will be affected, thus changing the answer of how many times you have to practice a week.

Many people will encounter bottlenecks after being familiar with an action. In fact, it is also the internal cause of the body. The body also needs a good rest to help the muscles return to their best condition. When you increase the amount of training, fatigue will also increase with the intensity. If you don't have enough rest, your body will not be able to bear. It will increase fatigue and reduce sports performance. If you don't have a good rest, you will overtrain.

Is it necessary to have a rest day for fitness?

Be sure, otherwise your body will be very tired later. You must make a reasonable plan with yourself to help your body recover and your muscles become stronger. It is enough for beginners to arrange training three or four times a week. The time outside the training day is used for rest and recovery. Remember, rest is as important as training.

After a period of time, you should learn to adjust your training plan to help your body become better, and you should have your own goals, be positive and complete the shaping of your body. If you master the correct method of each movement, you can start to increase the weight periodically. For example, gain some weight every two weeks, keep the same weight for two weeks and gradually increase the number of exercises, so that your strength and muscles will gradually increase.
