U respond to every question u properly explain in the video and in replays and this channel is just an all rounder
Thanks for the help
Hi Zakwan - thank you so much for your very kind comment (it is definitely one of our favourite comments of all time!). We are planning on filming new content in the new year, so let us know if there is anything in particular you would like to see! :)
Ayyyyy u pinned my comment THANKS

👍👍👍
This is just superb, I been tryin to find out about "good sit up" for a while now, and I think this has helped. Ever heard of - Bondraw Firm Ferriferous - (just google it ) ? Ive heard some amazing things about it and my friend got amazing results with it.

IMPORTANT - Breathe in through your nose on the way down. Breathe out at the top.
MIKE LYONS why
el1xs brxndt oh didnt know ty
potgg np I'm always there to help
Hi Potgg, Mike Lyons is correct, you want to breathe IN during the downwards phase and breathe OUT during the upwards phase. We have a video explaining this and talking through breathing when you exercise: ruclips.net/video/8Kt7vzTd5cs/видео.html Hope you find it useful!
Get Exercise Confident thanks
The trainer is so gentle :). It helped me understand better
I thought crunch is sit up. I see.

I followed the instructions of the crunches and was able to do 50 reps at once. It really hurt but felt very good. This was really helpful 👍👍
i am doing 300 crunches a day wbu?
@@purabus6470 have you got a six pack yet
@@treegoat5069 not yet
@@purabus6470 you’ll get there (as long as you do some cardio as well)
@@treegoat5069 Getting a six-pack has nothing to do with crunches or sit ups really, you can strengthen your muscles yes. But a six-pack is gained by lowering fat percentage (burn more calories than you intake)/ better diet.
This was bloody helpful. I never realizes that I was doing crunches incorrectly until Holly demonstrated the correct way to do it.
Bri'ish lol
Briish bro
Thanks for this! Now I can see there is a huge difference between a crunch and a sit up and now I'm going to do crunches only!
Thanks for great feedback Bianca!
I want a trainer like that 🥺 so gentle and kind. There's so many gym bros to deal with when you're looking for PTs
I just realized i was doing wrong crunches my whole life

I search for this because I am getting hip back pain for sit ups. Thank you for the proper crunches tips and techniques. :)
Progress: I just made 200 crunches in 1 day. Great exercise to core. :)
Awsome 👌 I'm just about to give crunches a try as pretty much any core exercise causes me lower back pain. Hoping this helps.
Thanks for making this video. I didn't really know the difference between the two. And now I know that sit-ups aren't good for you, so I'll just do more crunches to compensate.
Thank you being succinct and not blathering on about unrelated subjects. Subscribed.
Now here’s a man who’s taken more than a just a day trip round The Crunch.
you know nothing of the crunch!
I always got yelled at for doing crunches instead of sit-ups in gym :/
I'm glad I never listened to them
🔥🔥🔥
Didn’t realize there was a difference 👀
I feel so relieved thinking I don't need to go all the way up anymore...
Fr too hard
I've been doing crunches thinking it was a sit up my whole life
I usually skip this part
XD
And go straight to eating ice cream

Awesome explanation! I always wondered what the difference is and now I understand that as well as what they do for you. Thank you!
Thanks so much for your positive feedback Rayne :)
Is it just me that smiled a little when he said bum. Idk why I did tho 😂
Me 2
Omg he said bum😂🤣😂🤣😂🤣😂🤣😂🤣🤣🤣😂😂😂😂🤣🤣
It's the accent
dude i just start doing them today and i already feel like giving up lmao
Ive been struggling so hard to unlearn the improperly taught exercises i had in school years ago. I watch this, and for the first time i actually FEEL my abdomen getting worked! Ive been trying to be more active for awhile and finally moved to regular workouts but could never quite target the core. I was going mad 😂 thanks for the demonstration! Hopefully this will be a new years resolution i keep up
i usually do 30 sit ups. Now I tried these 30 crunches. My core hurts more with the crunches but with the sit ups I feel like its more aerobic cuz usually I start to breathe heavily as if I ran 100 meters
but the reason I dont like sit ups is because when you do them a lot they become worse for your bones and joints
7 years later and still super helpful
i feel like i can do a million sit ups but not a single crunch
I feel like crunches are easier
then u either mixed them up or you are doing the sit-up wrong ;)
@@Simon-bu4kc no....situps are way easier and less useful
@@Gl-my8fw not if you do them the right way. or let's at least say it depends on the kind of sit-up and the kind of crunch you are comparing
Damn situps are tough for me
It's been a while since I've done crunches and as I suspected I was doing them all wrong. Thanks for the video! This helped alot.
I really love this exercise
Crunches always confused me although I have a better grasp of how the exercise is done now. What I'm still not sure about is the part of tightening the muscles when going up and I'm not sure if I do it correctly and it also seems I can't go as far up as was shown in the video, I only lift a bit up from the ground (either because I'm doing it wrong or maybe I'm just not strong enough).
Perfectly explained, short and clear.
If it feels like it's stretching your stomach does that mean it's working?
Thanks for the great feedback Liquidcadmus!
This trainer is so supportive
Thanks so much Grace!
As a personal training and sports therapy channel, 8 couldn’t agree more with this, everything thinks sit ups are best but your really just exerting more energy and not getting any more benefit from the top part of the sit up!
Thanks so much Healthi, great to have feedback from another exercise specialist!
You might be right.
I put on a little more weight than I wanted, and I did some sit up (can't ever remember the last time I did them) and I did 30. I was going to come back and try for 50, and I noticed I had a strange pain. So I stopped. I'm going to try the crunches and hopefully it will get around that pain.
Thanks for gentleness and proper illustration. I have loved te the video.
seriously this is the best explanation in details for crunch and situps i've come across. Thank you so much for the video. Kudos!!
Thanks for the amazing feedback Jom!
I love this channel, you just explain everything that I've done wrong since I just watched instruction from youtube, thank you.
Thanks for the lovely feedback Ditha! Keep us updated on your progress.
i’ve been doing sit-ups this whole time and was struggling and my pe teachers never said anything
You trust your PE teacher??
guys don't worry i fact checked this with other sources and its legit
I've been doing crunches in p.e on accident...- when I don't want to finish my sit-ups, I barely do them- and it was exactly like a crunch- no wonder I didn't get in trouble
I've been doing it wrong then, still feel the pain but I'll do it right now.
Hi John, have you found the new technique has helped now?
i can feel i got pretty solid abs coz ive been doing 100 sit ups everyday but i still have fcking baby fats. gdi
Crunches don't burn fat they only build muscle.
Keep doing sit ups until you see your abs trough your fat
Tooo😂😫
burning fat and building muscle are separate things. Do cardio if you feel that you have muscles but still too much fat.
Saitama?
I’m gonna do 50 crunches each day for 3 days
Edit: Well it formed my abs a bit but I will try more days
how did it go?
You good bro? You still alive
Does anyone feel a bump near lowet back while doing crunches ?
@@Akash-cm5yo no but that could be cancer
@@Akash-cm5yo Yes I can feel my spine. My spine protrudes a little cause of my years of bad posture.
I was today years old when I learnt sit ups & crunches aren’t the same thing 🤯
Today, after the age of 30, I understood, crunches and sit ups are two different things
Thanks for this, i hav always had a problem doing sit ups, thought the crunch was inferior but i from what u hav explained i guess not, will try them, thanks..
Doing sit ups thinking of crunches started pain in my back, thats why I searched
Thankyou so much , I am getting better as more of them .
Thanks so much diorr!
I'm glad I saw this video. Now I know I've wasted a lot of time in situps
this was very helpful i had no idea that there was a difference in these two exercises. i hope that with this knowledge i can start doing proper crunches and maybe my tummy will start to look less like a potato lmfao!
so your telling me i’ve been doing crunches this whole time 😭
THIS MAKES SENSE😱
Awesome sauce 👌
I love right off the bat videos, keep up the great content❤️
Even better if one does NOT hold the head with the hands.
This strengthens the front of the neck...very important and overlooked.
Is it only me that though situps were squats 😂
No even me
Not me doing crunches thinking they were sit ups lol
i subbed cos this channel kindly responds every questions =)
Thanks so much Amsyong! We will be filming new content soon so let us know if there is anything you would particularly like to see :)
Oh! I've seen people saying to do crunches, and I've been doing them right, but thinking I was a failure by picturing a sit-ups in my head!
Thank you for the information.
Plain and simple I like this
I always felt like crunches were better because I just felt it way more and there was no extra movement to go all the way up. I would always do sit-ups tho because it was more popular up and it was introduced to me first.
very nice
Thank you for this demonstration, definitely cleared it up for me :)
Thanks for your feedback Dee, it is much appreciated :)
so i was doing a crunches the whole time,and it was in the right way!!! pheww thanks man
That was a very good video, I'm trying to get in shape so I can enlist and I just couldn't figure out why crunches sucked so freaking much, turns out I was going too high, bending my neck too much, not supporting my head, and not controlling my descent lollll. Thanks
Thanks for your kind message William - so pleased to hear that the video has been helpful, and great summary of the key points! Best of luck getting in shape and enlisting!
Do not enlist bro🙏😭
I doing crunches for an year only now I knew the perfect way .I am new to your channel 🇮🇳 from india
Annie dauntless so pleased to hear it has helped! And welcome to the channel 😄
@@GetExerciseConfident I am very happy for your response

This is so INTERESTING
Quick and to the point. Great!
wonderful explanation , very few explain in such an effective manner. Appreciable...
wow I have been doing crunches wrong this whole time.
Wow this will be better for me to do as I have long-term lower chronic back pain I can't manage sit ups it hurts to much.
My whole life I thought they were the same exercise but ppl use diff names
beautifully demonstrated
Thank you for explaining so well
So pleased to hear you found it useful Storm Willberg!
I come here to watch sit ups but after seeing this lady i forget all the things happen in my mind 😅😅
Are the crunches equally good for upper, mid and lower abs or do they focus on just one area? What other exercise do you recommend for bringing a big gut under control?
Hi alias dak, thanks for your great question.
The main muscle worked during the crunch is the rectus abdominis - the muscle that is known to make up the 'six pack'. What is really interesting about the rectus abdominis is that although it looks like multiple muscles, it is actually just a pair of muscles that run down in parallel from the bottom of your rib cage to the front of your pelvis. These two muscles have multiple horizontal 'tendinous intersections' which give the appearance of there being 6-8 separate muscles - but they are actually just a pair of continuous muscles.
Therefore, whenever you do a crunch you are working the whole of rectus abdominis and not one particular area (it is impossible to work only a part of it, just like when you do a bicep curl it is impossible to work only part of the bicep). You can feel this for yourself by putting your hand on your lower abdomen whilst you crunch - you will feel the lower part of the rectus abdominis contracting.
In terms of reducing the size of your stomach - exercises such as the crunch and the plank (ruclips.net/video/6LqqeBtFn9M/видео.html) are great for strengthening your core, but the best way to lose weight is through a combination of:
1) Cardio training (in particular interval training is very effective for weight loss).
2) Healthy diet (avoiding processed and sugary foods).
3) Resistance training (science shows that resistance training helps lose weight).
We've got some really good circuits on our channel which combine the cardio with resistance training, so feel free to give those a try: ruclips.net/video/8nwOUidIwgc/видео.html
Hope that helps and please let us know if you have any other questions! And make sure you let us know how you get on :)
Lmaoo I've been doing crunches this whole time thinking they were sit-ups
I don’t know why but my body keeps shaking when i do crunches..am i doing wrong?
Hi NightFlash, two questions:
1) Does the shaking start straight straight away or after a couple of crunches?
2) During which part of the crunch is your body shaking (up, down or both)?
Get Exercise Confident
1) it start straightaway sometimes but after a couple of crunches it starts shaking
2)down
My abs shake when I do the crunches after few times but I guess that's because the body is not trained yet. It's like when I first started weights my arms would shake because I was building the muscle, but it no longer does. Now I'm focusing on my abs and in my situation, it's just that I am trying to gain and define those muscles.
Hi Nightflash - the going down part of the crunch is actually the hardest part of the exercise (when done correctly with control). So if you have a bit of shaking just with that part then that's ok. You should find that as you get better the shaking will take longer to come on. Hope that helps and let us know how it gets on!
Get Exercise Confident i see, i shall take your advice then. Thank you for the info and help
What I get from this is: Sit-ups are oriented to keeping your body mobile and flexible.
Crunches are to strengthen the stability and resistance of core
That's a big oopsie from me, didn't know the difference
Since March 31st, along with diet change to eating only real food with negligible manmade crap, doing 40-50 of these crunches with the Tiffany Blair core routine, I've reduced my waist by a solid 4". I'm 66 yo, and with my 68 minute-1&8- of daily cardio cycling, I'm down 32 lbs since March 31st. Crunches, done like this, will bring about change. But there's more, other core attention, diet, and cardio to keep you going.
Thanks for this, you've saved me some grief~!!
This is so helpful. Thank you!!!
Hi. I had a silly question regarding workout in general. I've been working out for a week now and it's already taking me half the time to do the exact things I was doing at the beginning of the week. Does this mean I'm getting stronger or am I doing something wrong?
And your video gave me useful insight, so thank you!
Hi Elham - thanks for your great feedback.
The speed of the crunch should stay the same - as you need to be doing a controlled movement in order to work the abdominal muscles effectively - (as if you go too fast you will be using momentum instead). However, if you are doing it quicker because you don't need to rest as much between crunches then this means you are getting fitter.
Keep up the great work and let us know if you have any other questions. The GEC team.
Please make a video explaining how to do crunches without hurting your neck. I’ve always tried crunches my my neck ends up hurting
How do I keep my feet on the floor ? They always come up when I engage my core because I’m very weak. Maybe I should put my feet under something?
Hi Kittyin - thanks for your question. We would recommend that you avoid putting your feet under anything - as this will actually result in your hip flexors working more (and therefore your core muscles less).
We would recommend that instead you put your feet up on something (like a chair or bed) with your knees bent at a right angle. This will work the abdominal muscles just as well - so give it a go and let us know how you get on!
Get Exercise Confident thank you so much! Omg I can really feel my core working hard. Lifting my legs in the air has been perfect for me!
SO pleased to hear this helped Kittyin! :)
Kittyin Indy 😍😘
o
Than yous so much both of u❤
Good thing I can just do these instead. Situps were seriously injuring my tailbone even with padding.
Tip sit all the way up crunch a little bit
Is it okay if someone is supporting you while doing crunches?
(If somebody is stepping or sitting on your feet while doing a crunches)
Yes it is but you shouldnt because you would get to reliant
Hi Thanatos, if you find it more comfortable then yes its fine.
Sit-ups happen at pelvis and crunches at abs, you will feel immediate pain in abs once you start doing crunches
My height is 5 feet weight is 57 kg
How many cruches i should do to reduce belly fat
Good nutrition
Have a healthy diet...
Hi Sufiyan. Lautaro and Princexedrhic are both correct - crunches alone won't reduce stomach fat. The best way is a combination of cardio training (eg running /swimming / football), resistance training (eg squats / lunges) and healthy nutrition (low sugar diet). Try giving one of our circuits a go (which combine both): ruclips.net/video/8nwOUidIwgc/видео.html Let us know how you get on!
500 a day.
Thank soo much I do crunches considered them sit-ups my test is sit-ups I was thinking it's too difficult but sürprize sit-ups easy🎉🎉🎉
More importantly, you shouldn't do sit-ups like she did because she's using her arms as momentum to compensate for some weaker muscles. To gain the full benefit of the sit-up, her feet need to be weighted down or hooked and her arms should remain on her head because of the principle of moments, it will be more challenging when there is more weight at a greater distance from the pivot. The sit-ups is a perfectly legitimate exercise but can tire you out more than crunches because you are doing more work and engaging other muscles in a suboptimal way. This is the actual reason crunches are better for your abs, but you should be doing multiple types of exercise.
> ENGAGE CORE, RATHER THAN USE MOMENTUM.
> Exercise core, rather than strain neck.
> Proper form engaging the target muscles, before/above speed and number of reps.
Arnold Schwarzenegger recommends 200 of these a day.
Arnold was a professional hunk of meat. We mortals do not need to
Bruh my pe teacher made me do sit ups with my arms behind my head the whole time! No wonder everyone was bad at it
