Among the positive effects are the following:

increase in endurance;
payload on the cardiovascular system (blood pressure and breathing rhythm normalize);
weight loss due to the expenditure of a large number of calories (about 900 kcal per hour of training);
improved coordination;
improving the performance of the respiratory system.
But do not forget that excessive stress on the cardiovascular system harms it. People who have problems with blood vessels, the heart, as well as the ankle and knee ligaments, are not recommended to resort to such training. This can cause harm and aggravate old wounds and diseases. Do not immediately try to perform the exercise at a fast pace - increase it gradually from one workout to the next.
The main load goes to the calf muscles (about 70% of the total load), quadriceps and biceps of the thigh, buttocks and forearms are also involved. For 30 days of regular training, the blogger managed to get rid of three centimeters at the waist and 1.5 kg of weight. And this despite the fact that the guy did not experience problems with overweight and did not adhere to a special nutrition plan. Probably, the extra pounds would “leave” more willingly, and adjusting the diet would also enhance the effect. After all, everything is good in the complex.
