Just like its name, HIIT involves highly intensive natural body movements that have to be carried out over equal intervals of rest and exertion. The main focus is to maximize fat-loss by rapidly increasing and decreasing your heart rate. This triggers the body's blood flow to react accordingly which maximizes calorie. HIIT workouts typically use interval times with a specific work-to-rest ratio, such as 30 seconds of work and 15 seconds of rest (30:15). While there is no set rule on which interval times work best, typically the shorter the work time the more intense the exercise should be. Initially, the inertia of this type of exertion might cause fatigue, but isn't that the whole point of it?
Let us break a sacred bubble, THERE ARE NO SHORTCUTS! Individuals (especially youngsters) who are in a hurry to lose weight may think they need to cut way, way back on their caloric intake to gain maximum results quickly, but unfortunately this results in lower energy levels. Stick to a proper plan of action and be regular with your workout. Trust us, you'll be fit like a tank in no time!
Focus on all muscles, not just one: One of the biggest mistakes people make when performing HIIT exercises is focusing on a single muscle group. For example: frying your chest by performing focused continuous movements. HIIT is not about that. You will want to mix up your full-body exercises to achieve a proper HIIT workout. Work in exercises that challenge your body in ways more than one.
