Interval Training (HIIT) | Get Leaner with Less Cardio?

Can Interval Training help you strip off body fat faster? Learn how adding High Intensity Interval Training (HIIT) into your cardio routine can reap big rewards in strength, power and fat loss.

When most people think of cardio, they think of endless hours on a treadmill, elliptical machine, stair stepper or jogging. But unless you enjoy distance or long-duration cardio (for example, if you are training for a marathon or are a running enthusiast) , many gym-goers dread climbing on that hamster wheel each day in the hopes of burning off that 400 calories and maybe losing a little body fat along the way.

But what if there was a way to burn nearly the same amount of calories in 30 minutes that you do in 60 minutes, stimulate fat burning after your cardio is complete, boost your stamina and endurance, and actually increase lean muscle in the process?

There may be.

It’s called Interval Training — also known as “High Intensity Interval Training” or “HIIT“, for short — and it uses periods of high-intensity cardio coupled with lower-intensity recovery periods in succession to shave time off your cardio workout and possibly more fat off your midsection than long duration cardio. And even more promising, Interval Training seems to do a better job than long-duration cardio of preserving lean tissue (muscle) while still burning fat.

Interval Training: What Is It?

Simply put, Interval Training is a method of cardiovascular training that has you perform the same amount of total work that you would perform in a longer session of cardio, but in a much shorter period of time by increasing the intensity of your workout.  

Interval Training is considered an advanced form of training and is popular with everyone from elite Olympic and professional athletes to body builders, fitness enthusiasts and recreational runners.  While the technique is advanced, it can be successfully modified to work for beginners as well, provided you are in good health and are free of any cardiovascular disorders that could make the routine unsafe.

Interval Training relies on the principle of rest and recovery to allow your body to do more work in less time. By alternating higher-intensity activity with short rest and recovery periods, you are able to cumulatively do more work in less time. And more work translates into more calories burned in a 30 minute session of cardio than if you did the same duration of cardio at a lower intensity.

Examples of Interval Training

High Intensity Interval Training can be applied to nearly any cardiovascular activity, whether that’s walking, running, rollerblading or biking.

For example, if you are fit and regularly walk as part of your exercise routine, you might incorporate short periods (between 1-2 minutes) of jogging into your walk between lower-intensity periods of walking. If you are less fit, you might simply walk faster for a few minutes, allow yourself to recover and than repeat the higher intensity walking. If you are more highly conditioned, you might add in sprints to your daily run or treadmill work.

The Benefits of High Intensity Interval Training

High Intensity Interval Training has a number of benefits that make it an effective addition to your existing cardiovascular training. These benefits include:

• Burning more calories in less time
• Improved cardiovascular endurance
• Possible increases in whole body fat burning (fat oxidation) versus solid-state cardio
• Reduced risk of Metabolic Syndrome
• Decreased muscle catabolism/increases in lean muscle mass
• Improvements in arterial elasticity
• Reduced boredom with your current cardio routine

Let’s take a closer look at each of these potential benefits, including some of the research behind them.

How Often Should I Workout? | Fitness Tips

Workout frequency is highly individual. Learn how to find your perfect schedule and avoid over training.

How often you should work out is really a matter of your current fitness level, the types of exercises you are performing, the intensity of your workouts, and how much time you actually have available to spend in the gym.

Current Fitness Level

Your current fitness level is one of the primary factors used to determine workout frequency.

Beginners will typically need more recovery time between workouts than more advanced trainees, bodybuilders or well-conditioned athletes or runners.  Nearly everyone has experienced one of those workouts where you “over did” it and couldn’t move for three days. While this can happen at all levels of fitness, it’s more common among beginners who are still gauging their strength, stamina and recovery ability.

The body also makes certain adaptations with training over time that may shorten the required recovery time. So while some people can go heavy in the gym every day, others may need to take a break every-other-day.  

As a general rule of thumb, a good training frequency for someone who is new to the gym, or returning after a lengthy break, is three resistance workouts a week lasting between 45 and 60 minutes. This will allow you to work each major muscle group with at least one exercise and give yourself 48 hours for recovery between workouts.

This full-body workout is ideal because it helps build a solid foundation for later, more advanced training; encourages overall core development; discourages the development of muscle imbalances that can accompany “split routines”; and may burn more calories after training.

And by the way, this is actually also an excellent workout for an advanced trainee. The difference is they will work with heavier weights and may do more total sets for each exercise than a person who is less-experienced in the gym.

The Seven Healthy Habits of Highly Fit People

Adopt these seven, simple habits of really fit people and realize the benefits of a healthier body. 

Ever wonder how people who always seem to be in great physical shape got that way? More importantly how do they stay healthy, fit and in-shape?

Here are the seven healthy habits that almost all fit people seem to have in common:

Healthy Habit #1: They Eat

No one ever dieted their way to long term fitness and health. Despite the disturbing trend toward fad diets like Master Cleanse (which involve extreme calorie restriction or striking entire food groups from a person’s diet,)  well-conditioned, in-shape people eat.  And they actually eat a lot.

The difference between fit eaters and fat eaters, is that highly fit people eat differently — they tend to eat more whole, unprocessed foods; have higher lean protein intake; consume the bulk of their carbohydrates in the form of complex carbs like whole grains, vegetables and whole fruit; and avoid the “fat free food” trap.  They also tend to eat more frequently (as many as six to seven meals a day), but make those meals smaller. 

The result is that they have more stable blood sugar, more consistent energy levels, and are less prone to gaining body fat because they rarely eat more calories in any given meal than their body can utilize.
