Improve your cardio game with these HIIT treadmill workouts

Add these great cardio workouts to your usual gym routine

If you are a fan of running, then jogging along your favorite trail while you enjoy a beautiful spring or fall day may be one of your favorite things to do. While running outdoors has many physical and mental benefits, it may not always sound like the most enticing idea if you have to deal with winter weather or dark, cold mornings. This may be the optimal time to try some of the best HIIT treadmill workouts and exercise indoors!

Treadmill running can be boring and monotonous, with the minutes feeling like they stretch to an eternity. This is probably why some runners lovingly dub this useful piece of exercise equipment a “dreadmill.” Plodding along at a steady pace will mimic a glorious outdoor distance run, but it can make you long for the days of warmer weather and dry roads.

On the other hand, taking on a HIIT treadmill workout can not only boost your fitness and translate to faster race times and better running but also help the workout fly by. While HIIT treadmill workouts can certainly be challenging, they may just be the ticket you need to embrace treadmill running and boost your fitness. Not sure how to get started? Keep reading for our guide to the best HIIT treadmill workouts, and get ready to hit the speed-up arrow.

What are HIIT treadmill workouts?

HIIT stands for high-intensity interval training. It involves alternating short bursts of vigorous exercise with less intense recovery periods in cycles, which allow you to work harder during the intense periods and keep your heart rate elevated throughout the workout—even while you rest. HIIT workouts can be done with any sort of exercise, from squats and burpees to treadmill running.

When it comes to running, treadmills are an especially effective tool for HIIT workouts because you can program in specific speeds and inclines and watch the time right in front of you on the display rather than needing to check your watch and approximate paces on the road or track.

HIIT treadmill workouts, therefore, involve cycling between intervals of sprinting or fast running (or up steep inclines) and easy recovery jogs. Most HIIT workouts last anywhere from 15 to 45 minutes, but there are even HIIT styles, such as Tabata, that last just four minutes.

8 incredible ways you can benefit from cinnamon
Cinnamon doesn't just add flavor to meals — here's why it's great for you, too
Ground cinnamon and cinnamon sticks.

Unfortunately, the foods that are really good for you are not often considered the most delicious. On the other hand, the foods that we consider to be the tastiest are often loaded with sugar and fat. While very few people would argue against the fact that broccoli has a preferable nutritional profile compared to Oreo cookies, there are still foods out there that taste great and provide many perks. There are numerous benefits of cinnamon, for example.
Fortunately, there are plenty of delicious foods that are packed with health benefits, including spices and seasonings like garlic, cayenne pepper, and cinnamon. We often think of cinnamon as simply a flavorful accent to sweets like apple pie, spice cookies, and oatmeal, but cinnamon does more than just bring a scrumptious taste and aroma to your food. Keep reading to learn about the benefits of cinnamon.

What is cinnamon?
Cinnamon is a culinary spice made from the inner bark of cinnamon trees. After the cinnamon trees are cut down, the inner bark is harvested by stripping off the outer bark. The inner bark is then dried. As it dries, the bark curls into “cinnamon sticks,” which are rolls of the inner bark.
Cinnamon sticks are used to flavor things like tea and mulled cider and then are removed before eating. Ground cinnamon is made by crushing and grinding the cinnamon sticks.
There are two primary types of cinnamon: Cassia cinnamon and Ceylon cinnamon. Most cinnamon on grocery store shelves is Cassia, but Ceylon is known as true cinnamon, and it has a lighter and more mild taste but far more health and medicinal benefits. In fact, high doses of Cassia cinnamon can actually be toxic because it contains coumarin. If you have a bleeding disorder, you should consult your physician before consuming cinnamon in excess.
Moreover, to take advantage of the benefits of cinnamon, use Ceylon cinnamon.
