I Did the 12-3-30 Treadmill Challenge by Lauren Giraldo | HIIT or MISS for Weight Loss?!

Love this workout. I’m very short and I actually have a hard time waking at 3 mph so I go down a little to 2.5 and that usually gives me a good workout. Building up to the 3 mph.

One of my new favorite forms of cardio is dancing, whether that be following a dance workout video (if you know of any good ones pls send links) I used to love doing HIIT 5 days/week but was getting burnt out, I find dancing is intense enough to build up a healthy sweat and get my heartrate elevated but not so intense that my energy is crashed the next day. Also it's fun! I love the idea of doing 15-3-30 but Id probably get pretty bored and I don't have access to a treadmill

Does it make your thighs grow.... because now gap between my thighs are now lost 🥲

I feel same way towards walking. Clears my head and is my me time. I try to do it every day but not consistent when we hit fidget weather in Toronto, though like you I have a good parka and gear necessary to fight the elements 😂

What a great video. I gonna break this down in a video! I hope you will like it. + 1 sub 🏃‍♂️🏃‍♂️🏃‍♂️🏃‍♂️

Fun fact from a mental health professional, walking is actually a form of bilateral stimulation and because it's not very fast, it actually helps to recalibrate and regulate your nervous system. So that's why mental health walks are actually effective. That's also why people pace instinctively when they are nervous.

The music is awful -
Its like 5th grader tunes

The speed of 3 is in km/h or miles?

This video is a year old so im late to the game haha but in your ramen, what are those sprouts? I ate them in Thailand and dont know what they are called and havnt been able to find them!
Also, thanks for the content, very engaging :-)

I love that she was holding the book upside down 😂

OH MY GOD I WAS DOING IT AT 3 KM PER HOUR BEFORE I WATCHED YOUR VIDEO AND REALISED IT WAS MILES 😭😭😭 i was wondering why it wasn’t challenging 😭😭

I have a treadmill that does not go to 12. Would it be okay to do 10. 10-3-30. Plus I am in Canada so 3 is pretty slow. 10-5-30 heh

This is my firat video I am watching of you today. And some parts of the video were so wholesome that I can't help but subscribe so that I can watch you while I do my workout.

liss is good for people who cant lose weight due to excess cortisol.

the latte art is a bear or a dog

I’ve been trying to get to 3 but I can’t go to 30 mins by doing 3 the whole time so I’ve been walking at a range of 2.5-3.0 and fluctuating as I need I hope I can get to doing the same speed of 3 for the full 30 mins soon

Omg I tried this before it was a trend and I wanted to die

My go to workout lately is I do 12/3 warm up for about 10 mins the 20 min "hitt" run. Then 5 min dumbell workout, sally squats, abs and a stretch I think 12 3 is perfect for when you know you need to get to the gym but don't want to so you know you can at least do that, and usually end up doing more.

Hvnt seen this annoying video in ma life..with no valuable info

I do a mix of both. When I feel lazy or don't have the time to rest right after the workout and need to do other things right after the workout, I will do the "easy one" and then do hiit when I have time rest and take it easy after my workout.

This is the 4th video I am watching. I just subscribed. Your video content are fun and do give info

This hurt my hip sooooo badly. Be careful. 😬

Could you try heather robertson glow up challenge!

Also, an addition - if you're doing it for weightloss and restrict a lot, walking is so much better than HIIT

Where are your shoes from!?

Been doing this as a warm up for years can’t believe I’m ahead of the times 😂

I’m watching this video while doing 12,3,30 Hahahaha

My treadmill only goes up to 10. Any suggestions for an alternative combination?

That open land is pretty. So relaxing .

I love doing 15 incline at 3.5 for 30 minutes. I can't run a lot because I seem to always get injured so that intensity is perfect for me. I started out doing 12 3 30 but I felt like I needed to up it after two weeks.

i don’t do 12 3 30 because it’s too easy for me so i do 15 3.2 30

This was an interesting video to watch, thank you Keltie. I do want to point out something that I've learned (please do your own research too, don't just believe a random comment online) - the HIIT "afterburn" that everyone is talking about, actually equals around 30-40 calories which in the greater picture is really not that many calories. You can burn a lot more by doing LISS because you're able to do it for longer periods when compared to HIIT, where you can't really go over 15-20 minutes (if you can, that means you're just not going as hard as you can and that's not HIIT).

I used to do hitt everyday thinking I would lose lots of weight because it burns more calories. Turns out that’s not entirely true. I didn’t lose much weight with hitt so I just started doing regular cardio everyday like getting steps in and added some strength training. Turns out that helped a lot better for my body since everyone’s body works and reacts differently. Either way Hitt should only be done like 2-3 times in a week since it requires a lot of energy and then you need time for your body to recover too.

Lol u didnt even have 12 gradient on you been doing it flat...

another great video, thank you for posting!! :)

I love 12-3-30 for those days where I want to get some movement in but I don't feel up for something super high-intensity! I'm big into walking, it makes me feel grounded and helps me relieve stress so this is a great workout that I like to do once or twice a week.

Your hair looks great!!

OOOH GIRL CAN YOU SEND ME THE HOMEMADE RAMEN RECIPE??

Hate indoor cardio for the most part. To me, it is one of the most boring things on earth. I love lifting weights, hiking and mountain biking. So I have switched out the full body and HIIT days in my current training plan for 2-hour long mountain bike rides with friends. It's a mix of HIIT and steady-state, and some heavy lifting on the legs for climbs. It also makes me feel like a bad bitch haha. I am so glad that I have found the activities that I love. I finally feel like I can be healthy without "punishing" myself with exercise I hate. Fitness is awesome and it's a shame that it is often marketed to women as simply something that you have to force yourself to do so you can meet the standards of supposed atractiveness. Thanks for showing the real way to health and happiness keltie!

you never mentioned the calves situation... that is one of the reasons I didn't stick to it...

Hi keltie,
I always enjoy watching your videos, so please keep up the awesome work! On a different note, can you possibly do a video on whatever workout it is you are doing with the resistance bands? Please and thank you.

Lol yesss I needed Research Keltieeeee

what is the brand of your orange resistance band? let me know

A bit off topic, but damn some of the food you guys were making looked amazing!!! Is there any chance we will get to see Chef Keltie ?

how often do you take rest days per week and what do you do on those days?

I just want to say that you are absolutely glowing. Love to see it

L/MISS is great for people who deal with lots of daily exhaustion (you're more likely to injure yourself when you're tired, so HIIT is more of a risk) and for people with joint pain/arthritis. I have both 🥲😅 love me a good walk

I recommend reading the book “philosophy of walking” by Frèdèric Gros. I think you would enjoy it since it looks at walking from philosophical angle. :3

Fun. Seems too easy for someone like me that runs 12 miles a day 😅

the footage of your morning walk was so pleasing
