New research suggests Sprint Interval Training or SIT is better than HIIT. SIT burns more fat and builds more muscle in less time. Studies show SIT leads to greater fat loss compared to HIIT and traditional cardio. A typical SIT workout includes short sprints with longer rest periods. SIT ignites fast-twitch muscles and boosts metabolism.
