HIIT Cardio Routines on a Treadmill for Abs: Tabata Protocol
The Tabata protocol is a high-intensity interval training method that alternates between 20 seconds of maximum effort and 10 seconds of rest. This format is highly efficient for fat loss and muscle endurance. According to Izumi Tabata’s original research (1996), this type of training significantly improves both aerobic and anaerobic capacity. For example, a person might perform 8 rounds of 20 seconds sprinting followed by 10 seconds of rest.
HIIT Cardio Routines on a Treadmill for Abs: Pyramid Training
Pyramid training involves progressively increasing intensity before decreasing it again. This can help maintain high energy expenditure throughout the session. A typical routine might involve starting at a moderate speed, increasing every minute, and then descending back down. This form can yield both cardiovascular and muscular endurance benefits. It is beneficial for caloric expenditure and muscle retention, as highlighted by studies from the American Council on Exercise.
What Treadmill Workouts Can Help Maximize Fat Loss for Better Ab Definition?
To maximize fat loss for better abdominal definition, incorporate high-intensity interval training (HIIT) and incline workouts on the treadmill.
