HIIT stands for High Intensity Interval Training and as the name suggests, it is a form of cardiovascular exercise where the participant alternates short bursts of fierce anaerobic exercise with a less intense exercise such as walking. HIIT is very popular with athletes, fitness, models and bodybuilders looking to lower their body fat percentage without loosing muscle mass. HIIT is often performed for 20-40 minutes max and not as frequently as other forms of cardio such as LISS (Low Intensity Steady State), this is because HIIT has a much higher impact on joints, muscles and recovery.

Examples of HIIT Cardio:

  • Cycle at a casual pace for 60 seconds then flat out for 30 seconds, repeat 25 times.
  • Jog for 60 seconds then sprint for 30 seconds, repeat 20 times
  • Swim for 2 laps then flat out for 1 lap, repeat 15 times.

HIIT is often seen as a more effective method of cardiovascular training and more mentally stimulating. However, it’s also more mentally challenging and has a much higher impact on body. Anyone looking to add cardiovascular training to already intense training schedules may want to increase their calories and stick to lower intensity and lower impact exercises or else they may risk burning out.
