aHGer^83 SG

very long lei..
can some one summarise into simpler English or not?
not free to read lei... Mad

knightlll SG

The summary will be , stop doing sit-ups and crunches.

aHGer^83 SG

reason??

JoBonez SG

the core is actually supposed to prevent motion, situps and crunches do the opposite of this, they promote motion in the core. you ever hear of people who do a lot of situps and later got back pain? that is why

airgrinder SG

hey SD.

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??

davidche SG

(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)

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...

LyonK SG

Hmm...interesting.
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.

davidche SG

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).

davidche SG

try gymnastic's stretching exercises. It is so pain you cant even cry. Laughing ... Esp for beginners.

LyonK SG

gymnast honed their bodied for flexibility leh.

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

OPT SG

You have no idea what you are talking about do you....

From a standing posture how much recruitment of the rectus abdominus is required for forward flexion?

Keii SG

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.

davidche SG

stretch hamstrings.

Yes you relax your leg muscles but you flex you ab muscle to push you forward to strech MORE, than just gravity.

OPT SG

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.

galapogos SG

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.

eagle SG

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

Bar is active SG

Laughing

galapogos SG

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.

Anyway, this is a pretty advanced exercise that most people probably don't need to be doing for a while.
