HIIT is continuing to have its shining moment, and for good reason. By alternating between all-out effort through quick, intense bursts of exercise, followed by short recovery periods, HIIT (High-Intensity Interval Training) not only increases your metabolism and burns major calories, it also cuts your workout time in half, builds endurance, improves your heart health, reduces your risk of diabetes, and burns fat, not muscle. Sounds too good to be true, I know.
When you increase your heart rate and then bring it back down, your oxygen stores become depleted. Your body then has to work even harder to bring these levels back to equilibrium, burning more calories for up to 24 hours after your workout is over.
So you probably want to know – what’s the secret sauce?
5 Common Mistakes Made With HIIT
There’s a few things to consider when incorporating HIIT into your workout routine. Since it puts quite a bit of stress on your body, it’s important to make sure you’re not making any of these five common mistakes.
#1 You Do it Too Often
Less is more when it comes to HIIT workouts. Because of its intensity, your body needs more time between sessions to recover (remember, your body is still coming back to status quo even up to 24 hours later). If you are doing HIIT every day, you’re putting yourself at greater risk of burnout and injury. Instead, HIIT is the most effective when done two to four times per week on alternating days.
#2 Your Form is Incorrect
This is one of the most frequent mistakes seen in HIIT. Because HIIT requires giving all out effort, many people forget to monitor their form, putting them at risk for some pretty serious injuries and chronic pain. NEVER compromise your form for intensity or specialty exercises. Instead, choose exercises you know you can properly perform and start slow with new variations.
#3 Your Intervals Are Too Long
Intervals should be no longer than 30 seconds. After about 30 seconds, your immediate energy stores are depleted, and you’re more likely to give less effort and lose form. By only giving yourself 30 seconds to reach complete fatigue, you’re also more likely to push yourself to maximum effort.
#4 You’re Resting For Too Long Between Intervals
It’s important to give yourself enough rest between exercises and sets to be able to give all-out effort in your next interval. However, resting for too long can hinder your results. Aim for no more than 60-second breaks.
Note: those minute breaks should be saved for after super high-intensity bursts, and the majority of your rest should be at or under 30 seconds.
#5 You’re Not Incorporating Strength Training
HIIT should not replace your strength training. However, if your days in the gym are limited, combining your HIIT and strength training is a super effective way to burn calories and build muscle simultaneously. In fact, it can be an even more effective and time-saving way to burn fat while reducing the strain on your joints than a strict HIIT routine.
