High Intensity Interval Training, Is It For You?

crossfit_training_workout_exercises_basicWhen it comes to talking about working out, a common question I receive is, “what is the best type of exercise?” My first response is always this. Any exercise or form of physical activity that you find enjoyable and gets you moving certainly can count as the best type of exercise. I happen to love crossfit, but I completely understand that crossfit isn’t for everyone, just like running and Zumba isn’t for everyone either. The purpose of physical activity is to get the body moving and research has shown that individuals who move more have a lower risk of developing chronic diseases such as diabetes and heart disease compared to sedentary individuals. However, I will address the original question, “is there a best type of exercise/work out” or “are there exercises that do nothing for us?” The answer may actually be…yes.

Some of the best exercises are the ones that work several muscles at once and utilize many different joint actions. These exercises don’t even require equipment and can be performed at the gym, in the comfort of your own home, at the park and even a hotel room. They include the squat, lunge, push-up, plank and even the burpee. The beauty of these exercises is that there is a variety of modifications for all of them, whether it is to make them easier or more challenging for individuals of all fitness levels. These movements are also considered more functional, meaning they can help improve the ease of day-to-day activities such as bending over to pick up a sock, getting into and out of a car or lifting a heavier object.

The other side of the equation is the types of exercises that are less helpful for us. Many may disagree with this statement, but using machines is not one of my highest recommendations. Machines can be good for isolating specific muscle groups and they can help someone perform an exercise with more proper form; however, the downfall of using machines is that they often only require a single joint movement and they do not activate the core as efficiently as other exercise methods. Having a stronger core improves one’s posture and balance and can help reduce the risk of injury from everyday movements such as twisting to reach for something in the back seat, grabbing an item from the top cupboard or bending over to pick up a load of laundry. The other downside of using machines is that they do not hold a strong functional purpose. My crossfit coach, Molly Suholdanik also states, “We do not perform many single joint muscle movements in our day to day activities. We typically are always performing movements that recruit multiple muscle groups and joint actions at once.” This is why functional fitness training can be so important.

In the last few years, high intensity interval training (HIIT) has become increasingly popular. Many instructors and trainers now incorporate this method into a multitude of their classes and personal training sessions. HIIT is a form of training that incorporates short bursts of high intensity exercises followed by very short recovery periods. Typically I always teach a 4:00 Tabata sprint drill in my cycle class. Tabata is a 2:1 ratio of high intensity work to recovery period. In class, we will sprint for 20 seconds and then have a 10 second rest and this pattern is then repeated seven more times for a total of 4 minutes. A super app for this is Tabata Pro; it links with your music so you don’t have to utilize a stopwatch when working out to your favorite tunes.images

One of the most intriguing potential benefits of HIIT is that one can possibly achieve the same results (or even better results) with a shorter, higher intense workout compared to one that is longer and more moderate in intensity. Many studies suggest that even though longer, steady-state workouts may burn more calories, shorter, high-intensity workouts may prove to be better for fat loss. The reason for this extra fat burn is due to excess post-exercise oxygen consumption (EPOC). When performing a high-intense workout, the extra effort increases the body’s need for oxygen during exercise. This creates an oxygen shortage and causes the body to ask for more oxygen during recovery. This “afterburn” is the reason why the body continues to burn more calories and fat after a high-intense workout compared to a long, steady-state workout.

Here are some additional benefits of HIIT:

  • It’s efficient. Who wouldn’t want to achieve better results in a shorter period of time?
  • It can require little or no equipment.
  • Improves V02 Max (which is a fancy way of saying, it improves your ability to breathe and improves your endurance when working out)
  • Improves metabolism by increasing mitochondrial size.
  • Improves blood pressure, insulin and cholesterol levels.

Researchers suggest that HIIT can be performed 3 times per week. Since this type of exercise is so demanding on the body, adequate rest and recovery periods are needed to decrease the risk of injury. The purpose of this blog is not to convince everyone to start HIIT, rather I wanted to make more aware of the wonderful benefits that can be associated with incorporating some of these training methods into one’s workouts.

Pu-Pu-Push it Real Good!

If you had only 20 minutes to workout, what would be the best exercises to do to fill that time frame? Is it a crunch? How about the treadmill? Or does it possibly include that funny leg machine (a machine I particularly do not care for, but that can be explained in another blog post)? While the best workouts challenge all the major muscles of the body, there are a few exercises that rise triumphantly to the short-time-to-workout challenge. They include the Push-Up, the Plank and the Squat. Unfortunately, many of us developed an adverse relationship to these exercises from the days we took elementary PE. Learning the benefits, variations and different levels of application of these exercises will hopefully reignite your passion for these exercises.

Anatomy of a push-up

Proper Push-Up Techniques

Proper Push-Up Techniques

The push-up is a phenomenal exercise. It challenges the core, chest, triceps and even the front part of the shoulder. There are hundreds of variations and modifications to this exercise making it effective for exercisers of all fitness levels. Taking your knees to the ground shortens the lever length, which can make this exercise easier. To make it harder, try having your feet suspended in TRX bands. Don’t have the bands? No problem. You can simply elevate your feet using any raised platform or add additional movements with the exercise. Try a combination of push-up + jump knee tuck or push-up + jumping jack feet. Remember to breathe throughout the exercise; inhale on the way down, exhale as you push-up.

Modification Tip: If doing push-ups on your toes is too hard, but doing them on your knees is not hard enough, try this tip: begin in the up-plank phase on your toes. Lower your body into the push-up position. Then drop your knees to the floor to assist with the pushing up phase. Our muscles can take on a greater load during the eccentric movements of exercise (the going down part of the push-up) so this is a great way to effectively challenge your upper body muscles. Here is a great list of additional push-up exercises to try.

Drop it like a squat

Even as little tots, our bodies naturally follow proper form for a squat. As we get older, we tend to bend over to pick up things, versus squatting down. Remember to keep your chest elevated and your back flat when performing a squat. A simple technique to help you do this is by looking up rather than looking straight ahead. Maintain a straight back as you push your hips backwards and bend into the squat. Sometimes our anatomies get in the way of performing a good squat. Having your heels slightly elevated can help your body achieve the perfect squat. (Ladies, this is why squatting in heels is easier!)


Squat Tips

If you haven’t performed a squat in a long while, begin with your own body weight to help you establish good form. Our legs contain the largest muscles in our bodies. This is why it is important not to skip leg day because a large portion of our metabolically active tissue is found in our leg muscles. Leg muscles need to be challenged—and adding weight will not make your legs big. What you will notice is that they become more firm and sculpted. Here is a great leg workout created by Amy Dixon. I have personally taken many of her workout sessions at fitness conferences and love every single one of them!

Squats also come in myriad variations. You can narrow your stance (similar to chair pose in yoga) or turn your feet outward and sit straight down for a plié squat (dancer’s squat). Performing the squats with more weight or more quickly or adding a jump can all increase intensity. Here are some more squat ideas to try.

“Walk the plank!”

The plank is an exceptional exercise because it targets the core, as well as the upper and lower body. It doesn’t require a gym membership to perform, and the many variations of the plank will never leave you feeling bored with this exercise. The plank can be performed on your toes or knees. You can also move up and down with your upper body for another challenge (plank push-up).

To target the obliques, try a side plank variation. In the side plank position you can dip your hips down and up, curl your top arm down underneath you and back up or raise your top leg for added challenges. The question is, are you ready to challenge yourself?

This is why we plank.
