HIIT involves short intervals done at almost your max effort, followed by longer, slower recovery periods or rest. The secret to HIIT is in how hard you work during your intense intervals. Your goal is to work out at 90 percent of your max, which trains your body to work in anaerobic mode, which helps you become more efficient at producing and using energy.
The result? Your body's fat-burning potential increases, and the pounds melt away. So HIIT is where it's at when it comes to getting lean, but how often do you need to do it to see results? ACE-certified fitness trainer John Kersbergen said, "The most efficient way to get results is to do some form of high-intensity interval training HIIT for a total-body workout and to focus on strength training certain body parts upper body, lower body, core on different days of the week.
The findings were telling: Less intense training programs with shorter intervals carried the least health benefits, while interval training studies reporting the greatest increases typically used longer three- to five-minute intervals.
For this reason, athletes have long used the interval technique to up their game, Mayo Clinic exercise researcher Michael Joyner told Vox in One measure for blood pumping is something called stroke volume, or the volume of blood that comes out when the heart contracts. And a major determinant of VO2 max is stroke volume. Researchers have repeatedly shown that people can burn comparable amounts of calories in HIIT routines lasting, say, 20 minutes, compared to longer continuous exercise routines lasting, say, 50 minutes.
A systematic review of the trials comparing HIIT and SIT with moderate-intensity continuous training found all workouts performed about the same on fat loss. HIIT routines, by definition, tend to be shorter. So if your goal is weight loss, you might consider a longer interval routine, and you definitely want to look at your diet.
So that means the afterburn effect is greater after the intervals — but it peters out after a while. I saw the same effect when I entered a metabolic chamber to measure my metabolism. In the periods after I hit the exercise bike, my metabolic rate ramped up — but only by a few more calories each minute, and the effect wore off within half an hour of exercising.
Building more muscles, however, can be a little more helpful for the afterburn. At any given weight, the more muscle on your body, and the less fat, the higher your metabolic rate. But that takes work — a lot more work than a short aerobic HIIT workout.
And even a short HIIT workout may not be for everyone. Our mission has never been more vital than it is in this moment: to empower through understanding. We had an indoor M track so I would start about halfway across the short side just where there was a little workout area jog the long side, accelerate the short side, sprint the long side.
Slow down coming into the area, then do 10 pushups. I would keep doing this as a ladder for the pushups so it was 10,8,6,4,2,2,4,6,8, Absolutely dead by the end of it, with the combination of jogging sprinting and strength. It also ended up being about a mile of sprinting and 60 pushups. That sounds like an awesome workout, Hannah! I have been doing hiit with 5 exercises in the workout. By that I was really tired when the exercise was finished.
I wonder if I would get the same result if I did every exercise once and that repeated that 8 times still 20 min total? I tried that once, but at the end I wasnt that tired as usually. Is it the same if I just want to lose fat? What about if I want to gain muscle? Hey Metka! Good question.
Really depends on what exercise you are doing. You want to really push the intensity on the work period and if you do 2 exercises that work the same body part, you wont be able to push as hard.
Of course nutrition on both the fat loss goal slight calorie deficit and the muscle gain goal calorie surplus would have to be on point as well. Hope that helps!! My question is about HIIT. I have a back issue that prohibits my doing sprints, bicycling, and most aerobic workouts. I am able to use a recumbent stationary bike and will be doing the HIIT workouts on that. Is that OK? Is that advised? That sounds like a great approach, Barney.
You can absolutely do HIIT on a recumbent bike. In terms of how often you should do HIIT, I would recommend starting with HIIT workouts per week for the first weeks to allow your body to adapt to more intense workouts.
Listen to your body, and if you feel like your body is ready for more, add another day of HIIT. Alternating between HIIT workouts and stretching is a great way to keep your body limber and injury-free while doing more intense training. And you can definitely do HIIT in the morning, and a strength workout later in the day. Pay attention to how you feel during your strength workouts though — HIIT is intense and can take a lot of energy out of you.
Hi Barney. I read your comment and wanted to express how great your workouts will be on the Builtlean program and my experience with it. I am currently on week 5 of the program and am loving every minute of it. I am sure you will too. As far as the HIIT question, their workouts get your heart rate plenty high, especially the finishers at the end of the workout.
Also their workouts are very effective at targeting many muscle groups. I notice that various movements I do on a daily basis at work are becoming easier. My body overall is moving better and I am increasing strength. The warmups as well as cool downs they do also include stretching.
No doubt with your experience in a stretching regimen already that part will be a breeze for you. Have fun with their program. Take care. Thanks for sharing your experiences with BuiltLean Transformation, Tim! Keep up the great work, and Happy New Year! At the end of workout i am sweated and feel a bit exhausted eyes feeling closing down, body demanding water and i dont take any meal for next 1 hour. However Squats really make me feel like vomiting if i try to increase the reps or decrease the rest time.
Your suggestions are most welcome, but these are the only exercises i want to do in my HIIT, cant go for running cycling etc etc. No stress in my lifestyle, Healthy eating proper sleeping is there.
Main aim : Shredding fat at first, once thats done, building a medium toned physique. I recommend creating more precision with your nutrition regimen. Consider moving the KV swings until the end of the workout as they are a challenging exercise to combine with squats.
Enough of sweating and pumped up heartbeat. I am comfortable as well as pushing myself in this workout form, and nutrition is wholly balanced with minimum amounts of fat and carbs and maximum amount of green leafy and protein rich food, milk etc.
