High Intensity Interval Training

I only do HIIT for my cardio, no more than 40-60 minutes a week total, broken down in 20 minute sessions (on the treadmill).

It goes by so fast and it is actually pretty fun! I am past the days of spending hours on the elliptical or other boring cardio machines. I'm just trying to keep up my fitness level at this point.

I just started the Insanity workout with Shaun T. This is my 3rd day. I will be sure to check back and let you know how it works.

You burn more in the same amount of time and I find it less boring! I spend my time thinking of when to reduce/increase speed etc so time passes easier. Also fun to try to beat my fastest previous speed! It feels empowering

Though I've read before somewhere not to do it everyday as it is exhausting..

You should give it a try, mixes up your workout routine!

Its the best!

Im losing fat at the moment while keeping my muscle loss to a minimum.

I do x3 days a week HIIT circuits and x2 days a week Interval training.

HIIT creates an after burn effect which will help you burn more calories throughout the day.

Since starting my Cardio has dramaitically improved as a result of HIIT workouts.

I love it, gets you fit very quickly and great burns. I find the elliptical great for HIIT and run/walk.

Weight loss is 80% plus diet, 20% exercise. Weight loss happens in the kitchen, fitness happens in the gym. I do 30% carbs, but for now try...

40% carbs
30% protein
30% fat

Never go above 40% carbs

If you are going from the settings here is 55% carbs, which is too high.

Home, goals, change goals, custom...

Hope that helps!

I love HIIT, and especially all out sprints. But all out sprints do carry a risk of injury if you're not up for them. So don't go crazy right off the bat with it. Work your way up to all out sprints, or just do longer 1 - 2 minute intervals.

I've found that HIIT is great with an exercise bike. There is a low risk of pulling something, and you can just read a book or something during the rest interval (I do 30 second all effort, followed by 2 - 3 minute rest intervals).

I did Insanity in October and December. I lost 5 pounds (meh), but I also took 3 inches off my waist, 1.5 inches off my hips and 1.5 inches off each thigh (wish I'd measured more places, but those are the ones that matter to me). I got more definition in my calves, a new bulgy spot on the back of my lower thigh and some definition in my arms. I even got the beginnings of a line down the center of my abs and the sides of my abs went from convex to concave (hot damn, I'm getting abs). I was pretty damn pleased with myself. I also went from struggling to do one real push-up to doing SIXTEEN.

You need to do it like this: 3 min slow, 1-3 min fast (so fast you can barely breathe), repeat (try to do this for about 45 min). Do no more than twice a week. Three days, do easy workout for about an hour, then 1 day do easy workout for about 90 minutes. By "easy workout" that means between 50-75% Max HR. I've been doing this with the advice of a very established Personal Trainer, and it's given wonderful results.

For calorie counts, since I do it on a recumbent bike due to knee injury in the past, look up

Yea its a great site.

I did a free trial PT session today an realised that I could push myself an extra 20%.

My Heart Rate monitor definitely helped now I know where I need to keep my HR during Hiit sessions.

Yes, I've been doing this type of workout for about two and a half years now. I take classes at my gym like boot camp, training camp, Biggest Loser, etc. They're all HIIT type workouts where you do some high intensity cardio interrupted with floor work or lower intensity moves.

It keeps me engaged and works wonders for my strength and endurance. Plus it's just fun. For the first six months I did it, I lost no weight at all. Then one day it all started falling off and I dropped three sizes in a couple months. Currently, my gym is a bit of a drive out of my way, so I work out using HIIT about twice per week for an hour. That's pretty much enough, though three days a week is ideal for me.

I usually do two HIIT workouts a week, one of them heavy on the Plyo, the other using a speed rope and core exercises. They are tough, but I love the burn.

I have been doing it for app. 6 weeks with my fiancee and neither one of us had lost a pound?? I have adrenal failure that I am taking supplements for so am not really surprised by my lack of loss, but thought for sure he would have some loss. We warm up for about 3 minutes and then do 3- 30 second intervals where our heart rates elevate to 160-180, then rest. Any suggestions, maybe more time on the tread mill walking?

Have you taken measurements? With the Insanity workout (HIIT as well) I gained 2 lbs in 4 weeks but had lost 5 inches in just my waist/hips I'd stay away from the scale.

I did straight cardio (stationary bike) for a few months and then HIIT for the last few months. I would say I lost about the same amount of weight with each type of exercise. I do like HIIT more because it keeps you "busy" and kicks your *kitten* in a shorter amount of time. Also, after a HIIT routine your body continues to burn calories for a few hours. I would say just don't overdo it.

I discovered these guys' videos, which have some great HIIT routines (feel free to check out the other vids in my playlist):
