High intensity vs. low intensity cardio for fat loss?

(Allan Misner) #27

Sounds like a plan. But keep the HIIT to one time per week. If you do it right, it is a big stressor (albeit a good one) on the body. You’ll need a good week to recover from each session.

Yes, you have that right. You can just go slow, particularly if you’re on a bike. It is hard to just stop.

And 10 seconds is a great starting point.

My training is a lot of endurance/sweet spot work at the moment with like today occasion Z5 and 6 efforts …

Eli,

I’d be interested to know how many days per week you go to the gym and how long each visit is, plus clarity on your goals, and any injuries/conditions you may have. Some indication of your age, height, weight, waist and fitness might help as well.

Then, rather than asking what’s the best cardio, you might ask “What’s the best use of my time in the gym?”

No doubt you’d get loads of different answers. My big-picture thought as a 30 year gym owner is to use the exercise choices you do in the gym to stimulate an adaptive response (aerobic or anaerobic). This is in contrast to the time-wasting volume-based exercise many do in gyms, especially on treadmills, that is based upon CICO (calories in calories out) dogma.

@JamieHayes I only go to the gym on days i feel like it which as been 9 times in the last month about 60 minutes each time. usually a 45 minute cardio session which i enjoy. Followed by a 15 minute full body resistance circuit usually really light weights with mediocre effort as i am forcing my self to do it. I do a minimum of 2 30 minute walks outdoor every day usually breakfast and lunch time i also run one mile a week outdoors. I don’t really count these toward exercise as i did this even at my biggest. Current measurements: Height 5’8 weight 208lbs age 28 waist is 40.5 inches at belly button relaxed. My goals now are to reduce body fat. As far as injuries are concerned i separated my ac joint (grade 3) in a downhill mountain biking accident which is fine now as long as i don’t do any super heavy pushing lifts

Eli,

You may find a piece I wrote Introduction to Lifting of value.

I’d suggest that you create a plan, committing to the exact days and times that you’ll be going to the gym and put them in a default calendar as a weekly repeating meeting. Have your gym gear ready. Consistency trumps!

Personally, I’d make the weights circuit first, but change the weight you use on each exercise to a weight that’s light enough for you to do 8 very slow controlled reps (say 5 secs up and 5 secs down), and then do as many reps as you can endure. Record the machine, the weight and the reps on each exercise. If you can do 15 or more reps on any exercise, increase the weight by a small amount next time. Rinse and repeat!

The goal is to give your muscles an “overload stimulus” so that in the 24 - 72 hours after, your muscles will recover and adapt, get stronger and increase their blood-sugar-handling capacity.

When doing cardio, I’d try using interval training, where you walk uphill, or run, or sprint (on a bike or rower) for 20 seconds and go at a slow pace for 40 seconds. (There’s lots of combos. One I like is the 8/12 Lifesprints routines). Check out https://itunes.apple.com/au/artist/lifesprints/id320766623

Be careful of your AC joint. Let me know how the above goes. Good luck.

Thanks for the response this has motivated me to go in the garage and pull out all of my old workout journals. Seeing these old measurements and workouts i think will help me get back on track to lift :smiley:

I personally find that a fasted HIIT workout on a day that I am starting keto (if I’ve fallen off the wagon) it depletes glycogen stores and gets me into ketosis faster.

Also, fasted cardio in general, (HIIT or not) will make you better able to utilize cats which will only be beneficial for staying in ketosis as well as weight loss.

(Haley Kathryn) #35

I totally think you can, I would warm up for 10 minutes, and do 20 minutes of 15 seconds “sprint” and then the rest of the minute at a slower pace. During those 15 seconds you should be bringing your heart rate up so that you can feel you are working. Over time you can begin to increase the sprint duration.

You would also benefit from just Biking for half an hour or more at a comfortable pace, and incorporating HIIT after a few weeks.

Technically your NEAT will be your biggest fat burning over all compared to HIIT or LISS.

As has been said in here fat loss doesn’t need exercise. You can lose weight fine without it. Cardio is not efficient in the least and the body thins down to try to be efficient as the excess weight deters from the act of running. The body is an adaption machine. The goal shouldn’t be your weight but the ease to get to that weight. It’s easier to gain a lb of muscle than run all the time. Gaining that 1 lb increases your metabolism inheritly along with the keto boost you already have. This is important because the faster the metabolism the easier it is to lose fat.

Do both… I like sprinting up a hill on grass or going for a long walk… Jogging on the hard road doesn’t seem to agree with me… I am a big walking lunge fan, 400m of walking lunges then walk for a bit after is pretty cool… Combining both low intensity and high is good, row 500m / walk on an 10% incline treadmill for 5min then repeat as many time as you like… A few ideas

respectfully, disagree. to each their own! telling someone who wants to exercise indoors that it is crap is harsh.
i find being able to work out indoors when it is dark outside great. and also, safe!

(ryancrawcour) #40

i’d be careful. ease yourself in to it. HIT puts a lot of stress on a lot of things.

Here’s my tuppence worth/2 cents worth:

If you fancy the satisfaction of entering and completing a race (10K - full marathon) go for it. Do the training and enjoy your progress.
If you like being in the great outdoors and the time spent running is meditative, go for it.
But if your goal is to lose weight then go for HIIT

I did several 10Ks and a few half marathons in my 40s to try to halt the weight gain that was happening. Now I’m in my late 50s look back on those hours and hours training as time that I should have been with my family. As a weight loss technique, low intensity cardio really isn’t a good use of your time.

Dr Jacob Wilson has a number of these on HIIT and cardio and Keto.

It would be interesting to see if the same was true for ketonians with IR.
