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.
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.
This is a fat-burning, endurance, strength and flexibility workout. It is universal: it will suit those who want to lose weight, improve their body shape or simply maintain good shape and well-being.
