Maybe you’ve heard the hype about High Intensity Interval Training (HIIT) workouts and how they improve your cardiovascular fitness while helping you build lean muscle and burn fat. Guess what? It’s not hype! HIIT workouts work. I love doing and teaching these high-intensity workouts because they can be done in 30-minutes or less. Oh, and they are stinkin’ fun. Build muscle, burn calories, and boost metabolism all in one workout! Better body in less time? Sign me up! So if you’re new to this type of workout, know that HIIT for beginners doesn’t need to be intimidating: it’s all about knowing how HIIT works and how it can transform your body.
High Intensity Interval Training or HIIT is a type of workout where you give maximum effort through quick, intense bursts of exercise followed by short recovery periods. HIIT workouts train and condition both your aerobic and anaerobic energy systems. HIIT workouts get your heart rate up and improve your cardiovascular fitness level while burning more fat and calories in less time.

Sounds good right? Well, the key words to focus on are high intensity. Don’t be fooled by thinking that shorter workouts mean easier. HIIT training is not for the faint of heart. It’s intense, sweaty and doesn’t last long—but it works. Yes, HIIT involves short bursts of intense all-out effort, but here’s the good news: you know it’s over in 30 minutes!
Research shows that shorter, high-intensity workouts can do more for your health than longer, more leisurely workouts. HIIT also helps burn more fat at a faster rate. You can improve your heart health and significantly reduce your risk for metabolic syndrome, as well as a cluster of cardiovascular risk factors including obesity, high triglycerides, low levels of HDL cholesterol, high blood pressure and high blood sugar.
How does HIIT Training work?
The key to HIIT training that makes it different from basic intervals is that high intensity intervals involve maximum effort, not just a higher heart rate. So to differentiate from plain old intervals you have to push yourself to the max during the work portion followed by a period of recovery. The quick bursts of all-out effort, followed by less active recovery periods get your heart rate up and burns more fat in less time.
How is HIIT different from interval training?
HIIT workouts are different from other types of interval training because the high intensity intervals involve your MAX effort and not just a higher heart rate. The high intensity part of HIIT involves giving it your all for a certain amount of seconds (duration can vary).
Are there different types of HIIT training?
There are many ways to create high intensity intervals by changing the timing of the work vs. rest. I change up the interval timing of my live classes, but my absolute favorite type of HIIT is Tabata Training. Tabata-style takes high-intensity training to another level with workouts comprised of 20 seconds of all-out effort followed by 10 seconds of recovery, eight cycles in a row—a total of four minutes.
Tabata intervals can be incorporated into riding a bike, running, exercises using your body weight, plyometrics and strength training, but there is one variable that doesn’t change—the formula. You can do as many Tabata intervals in a row as you’d like but for most fitness enthusiasts, if you are going full out effort, 20-30 minutes is max.
How did Tabata-style intervals come about?
Tabata is named after Dr. Izumi Tabata who discovered that he could shorten the training time and vastly improve fitness levels with a specific HIIT regimen. He worked with the Japanese speed skating team and developed a timed interval program as described above. His research challenged the notion that you need a lot of time and miles under your feet to see results.
HIIT Class (Tabata style) can consist of bodyweight exercises, strength exercises, calisthenics or plyometrics. I recommend starting with light weights the first few sessions to figure out your limits. During the 20-second work portion, you have to go all out so you should try for as many reps as you can do without compromising form or range of motion. In my class, I verbally coach my members to figure that out. The funny thing is often newbies will keep working through the 10 second rest segments in the first Tabata interval due to their adrenaline kicking in … but quickly realize they are gasping for air and will be flat on the floor if they don’t use their 10 second rest segments wisely.

Who is HIIT for?
HIIT can be for all types of people, you just may not be using all out effort when you first start. HIIT helps people significantly improve their cardiovascular fitness, endurance, and fat loss without losing the muscle mass they already have. HIIT is for you if you want to try something new, if you want more for from your workout or if you are a diehard fitness enthusiast and you want a bigger challenge.
Nonetheless, If you’re just starting a workout routine or have been sidelined for sometime due to injury or life – the key to success lies in doing the moves with modifications, at your own pace. Yes, HIIT should be intense, but pushing too hard, too fast can result in injuries and other setbacks. My suggestion: listen to your body, use modifications where necessary, choose good form over speed and ease into how many HIIT workouts you do a week.

How often should I do HIIT?
If you are new to HIIT, just try one workout per week. If you are accustomed to working out, you can do HIIT three to five times max per week.
Safety Tips for HIIT Workouts
With the increased intensity, you can cause more wear and tear on your body, so make sure you follow these HIIT safety tips. Like I said before, HIIT can be for all types of people, but ideally, you should be able to exercise for 20 minutes without any issues before trying a HIIT workout. HIIT workouts are physically demanding, so build up your cardiovascular fitness slowly. You don’t want to overdo it.
If you have a sedentary lifestyle or are inactive, you may have an increased risk for coronary disease. Family history, cigarette smoking, hypertension, diabetes, abnormal cholesterol levels and obesity increase this risk, according to the American College of Sports Medicine. Make sure you check with your physician before trying any rigorous exercise program.
If you are new to working out, you can try HIIT workouts but with modifications for your current fitness level. If you are a beginner or new to HIIT, watch your heart rate, stop when you need to, and don’t do the plyometrics (or jumping movements) just yet. Start out with one HIIT workout per week with the ultimate goal of working yourself up to three times per week.
- Always warm up and cool down for at least five minutes before and after your HIIT workouts.
- Take time to recover from your HIIT workouts. Take at least one to two days off per week from HIIT workouts.
- Don’t push yourself if you are already sore.
- Start slowly and build your endurance and ability.
- Choose to do the modifications of movements that are too challenging for you.
- If you ever experience chest pain or difficulty breathing during your HIIT workouts, start to cool down.
- Don’t stop completely because your blood can pool in your extremities and cause lightheadedness, just stop the intensity and cool down slowly.
How many calories do HIIT workouts burn?
About ten calories per minute! (But wear a heart rate monitor for exact feedback.) Since HIIT workouts rev up your metabolism, you will continue to torch those calories long after you have finished your HIIT workout! Woo Hoo! Torch calories, blast fat and build muscle with HIIT!
