сделать упражнение . Надо выбрать правильный вариант

ответ:A series of exercises at the beginning is aimed at warming up muscles and ligaments before physical activity. It allows you to train much more efficiently, to avoid injuries and sprains.

In the warm-up, you should include cardio heating: jumping rope, walking with knees raised or running on the spot. Then you need to do joint gymnastics: rotation with your hands, arms, shoulders, head, etc. Now you can stretch for 2-3 minutes - you need to lock your arms behind your back to stretch your shoulder joints, and bend to the sides.

Finish the warm-up with the same cardio exercises as in the beginning, but at a higher pace. Then you need to restore breathing, alternating deep breaths
