The Ideal Duration for a Beginner's HIIT Workout.

High-intensity interval training (HIIT) is an efficient form of exercise that involves short bursts of high-intensity cardiovascular activity followed by brief periods of rest. A true HIIT session can deliver substantial fitness results in just 30 minutes or so, and it usually requires little to no equipment. HIIT can boost overall fitness, improve health metrics, increase calorie burn rate, and lead to better performance in competitive sports. A simple HIIT workout for beginners involves sprinting as fast as you can for 10 seconds on a treadmill, followed by walking or resting for 50 seconds, repeated six times. Another effective HIIT workout is the Tabata workout, which combines multiple movements over several rounds.
