HIGH-INTENSITY INTERVAL TRAINING

High-intensity interval training (HIIT), also called high-intensity intermittent exercise (HIIE) or sprint interval training (SIT), is a form of interval training, a cardiovascular exercise strategy alternating short periods of intense anaerobic exercise with less-intense recovery periods, until too exhausted to continue. Though there is no universal HIIT session duration, these intense workouts typically last under 30 minutes, with times varying based on a participant's current fitness level. The intensity of HIIT also depends on the duration of the session.

 

                                                        

 

HIIT workouts provide improved athletic capacity and condition as well as improved glucose metabolism. Compared with longer sessions typical of other regimens, HIIT may not be as effective for treating hyperlipidemia and obesity or improving muscle and bone mass. However, research has shown that HIIT regimens produced significant reductions in the fat mass of the whole body. Some researchers also note that HIIT requires "an extremely high level of subject motivation" and question whether the general population could safely or practically tolerate the extreme nature of the exercise regimen.

 

HIIT PRO'S 

 

• Burns more calories in a shorter amount of time. 
• Doesn’t require many sessions in a week to achieve results 
• Increases metabolic rate.
• Preserves muscle mass.
• Combines aerobic exercise with resistance training which can provide a stimulus for muscle growth.
• Incorporates a lot of variety in movements.

 

HIIT CON'S

 

• The intensity of the workouts can cause muscle soreness (DOMS). 
• Can’t be performed every day.
• Can lead to overtraining.
• Increased risk of injury if technique on exercises is compromised.
