Stop doing situps and crunches!

hey SD.Originally posted by Simon Dean:basically the purpose of the rectus abdominis is to prevent movement not create it.
Situps train against this function.
Long time never come in liao. Actually I dun quite understand your article. Too cheem for me lah.
So do you mean that doing sutups actually is bad?? -
(to TS) Actually for certain actions you do use the motions of a situp as well as the movement muscles that it trains. Eg would be bending down to take sth(i know wrong posture but many ppl do it) or streching your hamstrings, tie shoe lace(the part where you bend back up)Originally posted by airgrinder:hey SD.

However,what TS is emphasizing is the core muscles' effect/purpose of stablising the body; And this cannot be achieved by situps.
Which is why there is a new way of training your abs for stability purpose and that is to simply hold the push-up plank position. No movement at all.
TS: I really dont understand how your exercise works as i cant view the flash player thing. -
No, you don't perform the situp in any of those actions you have mentioned. Stretching the hamstrings doesn't involve any muscle shortening. It's a stretch for god's sake, you're lengthening the muscle. Getting back up from tying your shoelaces, or getting back up from picking something up involves hip and knee extension. The situp involves hip flexion and this is done by the hip flexors. They're completely opposite movements.
You really need to brush up on your anatomy... -

Sometime I jus stretch my hamstring while playing rugby.
Sometimes I pull my hamstring.
I fear one day my hamstring just snap and I go crashing down. -
you are right and wrong. You got your facts right but you got what i said wrong. The wrong posture of picking up a thing is to simply bend down without bending the knees. Also, when tying your shoe laces, you bend down(yes, bend down) while at the same time bending your knees. So after that you straighten your knees(and then what happens?), you maintain that bent-back walking around the streets? Of course not!!(you bend back).Originally posted by galapogos:No, you don't perform the situp in any of those actions you have mentioned.

... Esp for beginners. -

I just need ability to cover distance...not do sommersaults -

From a standing posture how much recruitment of the rectus abdominus is required for forward flexion? -
From what I've read. You guys are blasting each other about this, even the mods.
At least suggest an alternative for those non-gym goers who still wanna look a lil' buff? Instead of provoking each other. -

Yes you relax your leg muscles but you flex you ab muscle to push you forward to strech MORE, than just gravity. -
just give up - you dont know what you are talking about
by they way it is hip flexors that creates forward flexion from the hip - you might want to get your facts right before making statements like this. -
We're not blasting. There is a need to correct misinformation when we see it, and what david has mentioned is misinformation that needs to be corrected, lest other people start believing in it.Originally posted by Keii:From what I've read. You guys are blasting each other about this, even the mods.

I just took time to actually re-read the full article at the website and saw the video of OPT doing his developed exercise. It was quite nice.
I have 2 questions.
Every time when I train abs using the lats pull down bar, doesn't it work the same way as your strength band? The motion looks the same; there's also a force that will explosively pull me back up.
And about doing situps. Wouldn't the force of gravity pull you back 'explosively' to the actual position too?
Thanks for clarification -

Different. The cable crunches work the same way as traditional crunches. You're creating movement, not resisting it. You're using your core to pull down the cable, and then just letting it fling you back up once you're at the bottom. With the EAD, you're using your hip to bring the band down, and then resisting the back extension with your core, which is one of the functions of the core.Originally posted by eagle:I just took time to actually re-read the full article at the website and saw the video of OPT doing his developed exercise.

Anyway, this is a pretty advanced exercise that most people probably don't need to be doing for a while. -
I do use the cable to teach people the mechanics of the exercise but don't load it too much instead focusing on the technique and timing.

While we're on this subject, what's the effect of doing sit-ups with your back straight?
-
Doesnt matter, dont even do it.You are still producing flexion more from the hips.Yea sure, situps work the abs but not the way that its scientifically made to work.Abs are actually to stabilise more rather than to move..Originally posted by Kuali Baba:While we're on this subject, what's the effect of doing sit-ups with your back straight?
There are other better ways to train the core.
