Interval Training Workouts for Weight Loss

Interval training is a popular method for increasing workout intensity to burn more calories and lose weight (body fat) faster. By definition, interval training is physical exercise routine that intersperses bursts of high-intensity (vigorous cardiovascular or aerobic) work with periods of lower-intensity work. The high-intensity periods should match your fitness level (longer high-intensity intervals for advanced exercisers). Strive to workout for at least 20 minutes (including warm-up and cool-down).

Interval training basics

You can engage in an interval training workout using a variety of exercise machines (stationary bicycle, treadmill, elliptical trainer and/or rowing machine) as well as outdoors. Interval training is used in many sports’ training. The American Council on Exercise (ACE) recommends performing at least one (if not two) circuit or interval training workouts weekly to overcome weight loss plateaus and challenge your body. Interval training takes your exercise routine to a new level. The recommended methods for making the high-intensity intervals ‘tough’ include increasing resistance, speed or incline. A simple interval training cycle might involve cycling at a higher resistance level/faster pace for one minute and then reducing the resistance level/slowing your pace for two minutes. You’ll repeat this cycle several times depending upon the length of your workout.

Interval training: Importance of RPE

Use perceived rate of exertion (RPE) to gauge how hard you are working (1 = easiest, 10 = most strenuous). Begin your interval workout with a 5-minute warm up on your cardiovascular machine. Begin your interval training workout with a 5-minute warm up (RPE of 3 to 4) followed by 20 to 30 minutes of cycles alternating high-intensity periods with shorter, less intense or ‘recovery’ periods. During the high-intensity periods, work at a RPE of 7 to 8 and during the less-intense periods, work at a RPE of 5 to 6. End your workout with a 5-minute cool-down at a RPE of 3 to 4.

Boot camp interval training

Have you ever participated in a boot camp-style workout? These high-energy group workouts often more sophisticated interval training. During a boot-camp style workout (in a gym) you might engage in cardiovascular intervals (jump roping intervals followed by recovery jogs). Another method is to combine interval training with circuit training. You can do this yourself or in a small group. Circuit training basically involves going from one exercise to the next, doing different exercises on using various exercise equipment.

Interval training plus circuit training

Combine both styles of training by performing one set (in fairly rapid sequence) of three to five challenging strength training exercises (after a 5 minute warm-up). Sample exercises might include squats to overhead presses (with dumbbells); straight-leg push-ups with alternating dumbbell rows (one row after each push-up) and alternating lunges with bicep curls.

Next, jump on a piece of cardiovascular equipment, such as an elliptical trainer for about six or seven minutes, alternating high intensity 30 second ‘intervals’ (faster speed and higher tension) with lower-intensity recovery periods for 45 seconds to one minute. Immediately complete another set of your three to five strength training exercises (do the same exercises, choose different exercises that target the same muscles or alternate upper and lower body focused exercises). Keep in mind that compound exercises (such as squat to overhead press) are time-savers as they work multiple muscle groups simultaneously. All the while, your heart-rate remains elevated since you are never really ‘resting.’

After the second set of strength training exercises, jump on another piece of cardiovascular exercise equipment, such as a rowing machine, for another six to seven minutes for interval training. Again, alternate 30 seconds of faster rowing periods (and/or increasing tension) 45 second to one minute periods of ‘recovery’ rowing.

Do this one more time with another set of three to five strength training exercises and another six to seven minutes of interval training on another cardiovascular exercise machine, such as a treadmill. Finish this workout with a 5-minute cool down. At the end, you’ve completed a 45-minute to 1 hour workout that blasts calories and fat. Interval training, with or without circuits, keeps the intensity and pace high throughout your workout.

Interval training benefits

Two of the most significant and rewarding benefits of interval training are that it beats boredom and torches more calories in less time, aiding in weight loss. Scientific studies indicate that interval training workouts build muscle endurance more quickly than traditional (static) workouts.

Asparagus nutrition information and benefits

Did you know that the tender spears (of asparagus) were very popular in the royal households of 17th century France? Asparagus was believed to be a powerful aphrodisiac! Well now spring is here and you can enjoy this ‘in season’ fresh vegetable for its many benefits (aside from the above)! If you have tried asparagus and loved it, good for you. If not, perhaps you have eaten asparagus that was prepared incorrectly (under-seasoned and over-cooked), making it mushy and bland. At only four calories per spear, asparagus is a low-calorie vegetable packed with nutrients and disease-fighting compounds.

Asparagus: nutrition information

In addition to being low in calories, asparagus is a great source of the B-vitamin folate and a good source of both vitamins A and C. Five spears provides 20 calories, no fat and 110 micrograms (mcg) of folate, which meets 28% of the recommended Daily Value (DV). Optimal folate intake is crucial for a healthy pregnancy, making new cells and forming neurotransmitters, or chemical messengers in the brain. Folate is also important for reducing your risk of developing heart disease. It controls the amount of homocysteine (an amino acid) in your bloodstream. When folate levels plummet in your system, homocysteine levels increase, causing damage to the delicate arteries which supply brain to your brain and heart. Keep in mind that folate is highly susceptible to destruction through cooking (heat, air, light) so cook your asparagus whole (briefly) and don’t submerge it in water.

Vitamins A and C are antioxidants. They protect cell membranes from damage and promote a healthy immune system. Vitamin A plays a role in the creation of new cells, reproduction, growth and development, promotes healthy eyesight among other functions. Vitamin C is needed to form collagen, a fibrous protein that acts like cement in your body, along with elastin it gives your tissues form and provides firmness and strength. Without these substances, your body would fall apart. One serving of asparagus, or five spears, meets 10% of the DV for vitamin A and 15% for vitamin C.

Asparagus contains a powerful compound which acts like an antioxidant, offering protection against cancer. It is called glutathione (a small protein). Like vitamins A and C, glutathione protects cells against free radical damage which can, at worst, lead to cancerous changes. In fact, in an analysis of nearly 40 green vegetables, fresh cooked asparagus came in #1 for glutathione content.

Asparagus selection and storage

Choose odorless asparagus with dry, tight or compact tips (most of the nutrients are in the tips!) versus loose, frayed tips. You can refrigerate fresh asparagus for up to four days. Simply wrap the ends of the stalks in a wet paper towel and placing the asparagus in a plastic bag. When preparing, remove the woody stalk or the point where it naturally ‘snaps’ off toward the bottom of the stalk. If they are very thick stalks, try using a vegetable peeler to remove some of the exterior and make it easier to find the woody part, which you can cut off with a knife.

Preparing flavorful asparagus

Never overcook your asparagus. It is best ‘al dente.’ Try grilling it or cooking it in a pan with a bit of oil (browning the sides). Make a orange-soy dressing or marinade with about 1 TB each of reduced-sodium soy sauce and fresh orange juice, 1/2 tsp each grated fresh ginger, orange rind and sesame oil. Toss it in the mixture before steaming, browning in a pan or grilling. Top with diced shallots, if desired.

Other varieties

When we think of asparagus in the U.S. we typically think of ‘green’ asparagus. White asparagus is not a different variety of asparagus but is grown using a different cultivation technique. It is more popular in Europe and tastes slightly less bitter than its green cousin. Purple asparagus, originally cultivated in Italy, is actaully a different variety and has more sugar and less dietary fiber than green asparagus.

Obesity and our children

Where are we in our fight against the “war on childhood obesity” in the United States? According to the American Academy of Child and Adolescent Psychiatry, between 16% and 33% of children and teenagers are obese. Obesity increases the risk of suffering from chronic conditions and illnesses, such as heart disease. Recently, First Lady Michelle Obama has brought the spotlight back onto this issue, giving it a fresh perspective. The first step in preventing, and even reversing, this disturbing health crisis is in publicizing it or increasing awareness through media venues, campaigns, partnerships and alliances. The goal of the “Let’s Move” campaign is to improve nutrition and reduce childhood obesity. As a mom and a very prominent public figure, Michelle Obama realizes that with power comes a responsibility to make a difference through awareness and action. Most Americans don’t realize that obesity is the most common form of malnutrition in the United States today.

Childhood Obesity: “Let’s Move” Accomplishments

What has “Let’s Move” accomplished to defeat childhood obesity? Many large corporations and non-profit organizations have come forward, willing to donate time, money and resources to this cause. The National Hockey League (NHL), Major League Baseball (MLB) and Disney have all teamed up with “Let’s Move” to create public service announcements (PSAs). These PSAs feature actors and athletes, who inspire kids to sign up for team sports and get active.

Raising healthier kids is no small undertaking. Luckily there are plenty of resources available, national and local, on- and off-line such as your state’s department of health services. Act now, act quickly. Start slowly.

Suggestions:

1. Keep plenty of healthy foods in your home for quick snacks and meals, such as low- or non-fat yogurt, whole-grain crackers, fruits and vegetables and lean meats.

2. Play with your children, in and/or outdoors. Exercise reduces the risk for childhood and adolescent obesity.

3. Set an example. Live healthfully and show your child how it is done.
