Most often, when working in a sedentary job, skeletal muscles become stiff, less coordinated or weakened, which can cause discomfort or pain, especially in the back.
HIIT (HIGH-INTENSITY INTERVAL TRAINING) - is a cardio type of training, during which the heart muscles are activated by combining high and low-intensity exercises and rest periods.
This is functional strength training that occurs on a circular basis: athletes walk in a circle through exercise "stations" and perform physical exercises for specific muscle groups within a certain time interval. Each station provides an opportunity to perform various exercises that develop coordination and improve physical fitness, strength, and endurance.
