High-intensity training (HIT) significantly enhances caloric burn during and after workouts due to the afterburn effect, where the body continues to expend energy post-exercise to recover. This training increases heart rate and metabolic rate more than steady-state exercises, facilitating greater overall calorie expenditure. Engaging in HIT can also improve muscle mass, which contributes to a higher resting metabolic rate. Thus, HIT is effective for those seeking quick and efficient ways to maximize caloric burn and improve fitness levels.
