What is High-Intensity Interval Training (HIIT)?

High-Intensity Interval Training (HIIT) is a simple but effective form of exercise.

To do a HIIT workout, you will alternate short periods of high-intensity work, followed by more extended periods of low-intensity work or rest. For example, in a 20 – 30-minute workout routine, you may do 15 – 20 minutes of low-intensity work and 10 minutes or less of high-intensity work.

HIIT is a powerful fat-burning workout that you can do in less than 30 minutes and with less than 10 minutes of actual work!

Benefits of HIIT Leg Workouts

Regardless of intensity, exercise puts stress on your body. When facing this stress, your body adapts and grows to make it easier to handle the stress in the future.

Despite being a short workout, high-intensity interval training still puts enormous pressure on your body, resulting in increased calorie burning and fat loss.

For example, a 2007 study published in the Journal of Applied Physiology stated that 7 sessions of HIIT over 2 weeks showed an increase in fat oxidation by about 30%, meaning you burn more fat with high-intensity interval training!

A 2007 study published in Medicine & Science in Sports and Exercise concluded that a 15-week exercise program showed that interval training lowers insulin levels and can increase fat oxidation, showing greater fat loss in the long term.

Furthermore, a 2015 study published in Obesity Reviews stated that HIIT programs are more effective at lowering fasting glucose levels and improving metabolic health in those with Type 2 diabetes.

The point is that HIIT is effective at burning fat, lowering insulin and glucose levels, improving metabolic health, and helping your body adjust to intense workouts.

High-Intensity Interval Training (HIIT) vs. Low or Moderate Intensity Workouts

HIIT works well, but does high-intensity interval training work better than low or moderate-intensity workouts? A high-intensity workout puts more significant stress on the body, forcing it to grow and adapt more than during a low-intensity workout. But, as with anything in life, what you put in is what you get out.

Studies show that:

  • 3 HIIT sessions per week for 8 weeks has been shown to increase VO2max (this is how well you utilize oxygen, a common measure of cardiovascular health) and increase fat loss [East Tennessee State University (2001)]
  • HIIT results in higher energy expenditure over 24 hours, meaning that you will continue to burn calories after your workout [Medicine & Science in Sports & Exercise (1996). Why? This is a difficult workout, so your body will work harder to recover and will use more energy (calories) even after exercise.
  • HIIT is superior over low or moderate intensity training for reversing the risk factors of metabolic syndrome (conditions that increase risk of heart disease, diabetes, and stroke) in a 16-week study of 32 adults with metabolic syndrome [Circulation (2008)]

HIIT Benefits

HIIT workouts are more effective at burning fat, burning calories after a workout, and improving metabolic health than standard low to moderate-intensity cardio.

Here are a few tips you need to know to get the most out of your HIIT leg workouts:

HIIT Leg Workouts RPE (Rate of Perceived Exertion)

Your HIIT leg workouts should be intense because you are only going to exercise for a short amount of time, and the results of the workout depend on your intensity.

You want the high-intensity period to be about 80% or higher of your max heart rate and the low-intensity period to be about 40-50%.

For those who do not use heart rate monitors a lot, the high intensity should feel challenging. It should be difficult to carry on a conversation, and you should feel like you really put work in.

The low-intensity period should feel comfortable. It is a recovery phase and should help bring your heart rate down. But keep moving!

How Long Should a High-Intensity Leg Workout Last?

There are various options for HIIT leg workout duration. As I mentioned before, for the Tabata Interval workout program, you will do eight short rounds of 20-seconds, followed by shorter rest periods of 10-seconds.

In other workouts, you could do maybe 30 seconds to 1-minute of high-intensity work, and 1 minute to 2 minutes before recovery. However, a 1:3 or 1:4 ratio is a good starting point while adjusting to this workout program.

Furthermore, you should do about 5 to 12 interval cycles (high intensity + low intensity = 1 time), but this will vary.

The ACSM recommends doing one HIIT routine while starting out, then increasing to two routines per week. Of course, make sure you give yourself time to recover between each, but you can do HIIT leg workouts up to three times per week as you adapt.

Best Leg Exercises for HIIT Leg Workouts

There are a wide variety of leg exercises you can use during your own HIIT leg workouts. A few of the best leg exercises for HIIT workouts include:

Best HIIT Leg Workouts at Home

Although some of the equipment you need for some HIIT leg workouts can only be found in gyms or fitness centers, there are a lot of HIIT leg workouts you can do at home. As I mentioned a few times, the Tabata interval protocol is a great option.

The Tabata interval protocol was the first High-Intensity Interval Training (HIIT) workout routine I learned.

Doctor Izumi Tabata discovered the “Tabata Interval Protocol” all the way back in 1996 when he and a group of researchers were studying the effects of moderate-intensity training versus high-intensity interval training on anaerobic training capacity.

The Tabata interval method was originally tested using a stationary bike.

Tabata intervals consist of eight sets of 20-second max efforts-where you push yourself as hard as possible (at about 170% of your VO2Max), followed by only 10 seconds of rest, creating a 2:1 work-to-rest ratio.

Although you can use the Tabata interval training method with nearly any exercise, it is more effective with some than others. For your HIIT leg workout at home, I suggest you do Tabata intervals with body squats, lunges, or burpees.

Along with Tabata intervals, my next suggestion for you is to subscribe to BodyFit by Bodybuilding.com and take advantage of all the HIIT leg workouts they offer.

As mentioned previously as well, I also suggest you check out the workout plans that are listed on the BodyFit App. Tabata Intervals are amazing, but there are other HIIT leg workouts you can try as well!
