After all, if you have little rest between repetitions (sets), then you will get a strong load on the heart.
It is very important to breathe correctly during training and proper posture during the break between sets.
During the break, you should not sit, because the seated person inhales a smaller amount of oxygen.
In the intervals of sets, you can stretch the muscles to speed up their recovery.
It should also be noted that during training for strength or weight, we make a small number of repetitions with a lot of weight, we need to increase the time to rest between sets.
At lunch, at work, a sandwich with tea or a meal will go into the dining room with soup or borsch.
Well, in the evening, when a tired and hungry person came home from work, he would have a meal of soup + potatoes or pasta.
As you can see, this food is not ideal, for a simple person it can and will fit, but for an athlete the bodybuilder is not suitable at all.
In this diet there are very few calories, and almost no protein. And since no protein means and there will be no growth of muscles! To do this, you need to change your diet, go for 4 or 5 meals a day, you can eat smaller portions but more often, so the food will be better absorbed and less stress will be on the digestive system.
See the table of products with a low glycemic index. These foods contain normal carbohydrates, which do not turn into fat so much. Eat food rich in protein, it does not turn into fat, minus very few in nature there are such products that in addition to protein did not contain more fats and carbohydrates. Look at the caloric content table of foods and choose foods high in protein and low in fat and carbohydrates.
Fish is an ideal example, but look carefully at the table there are different kinds of fish, there is a fish with a lot of fat, how to cook such fish, do not recommend it, because it absorbs a lot of vegetable fat if you fry in sunflower oil.
The ideal option is to cook it in a double boiler, such food will be useful, it will contain vitamins, too, because with this treatment with not high temperature, more useful substances are stored.
Is pumping useful?
There are different opinions, some argue that it is useful because a strengthened blood flow brings many useful substances to the muscles, others claim that it is dangerous to the muscles on the verge and if it is still added to the load, you can get injured by a rupture of the skin or muscle. But the right answer yet, as well as the evidence for this.
Professional Greg Titus says that when training with great repetitions (fast), his training takes 40 a maximum of 45 minutes, he achieves pumping and good muscle growth. He trains so that the last repetition he did with difficulty and felt as much pain in the muscle.
He claims that aerobic stresses stimulate the production of growth hormone and other anabolic hormones. You can reach pumping with a lot of weight, but you need to train longer.
