“…sometimes called a curl-up”?
Isn't a curl-up done from an inverted hanging position? --— Poga — 13:36, 20 October 2006 (UTC)

if it is sometimes mistaken for a curl-up, should there not be a page explaining what a curl-up is? easytiger 17:39, 20 April 2007 (UTC)

Crunch Rest Period
In most weightlifting exercises, you are supposed to wait at least a day to allow your muscles to rest and rebuild. Does this apply to calisthenics also? Should you wait a day before performing crunches again, if you do them in large sets (100+)? Rayman123 02:16, 22 February 2007 (UTC)

Curl-up -> Crunch
I wikilinked curl-up, and quickly noticed that the destination page references back to Crunch. However, the Crunch page indicates that this exercise is often mistaken for a curl-up, which is sort of a bit confusing. While I can fix this by changing it to be a.k.a. curl-up, I think this is merely a quick fix. Comments? --Sigma 7 03:02, 19 May 2007 (UTC)

As I mentioned above, I'm fairly certain that a curl-up is an entirely different exercise. It is done when one hangs from a bar (or other similar apparatus), commonly by hooking the knees over it, and then 'curling' the torso up to a position parallel to the ground—and sometimes even higher, bringing the face to the knees. As such, the reference to the curl-up in this article would seem to be inaccurate. — Poga — (talk) 08:32, 31 December 2007 (UTC)

You need a better picture. That double picture does not show the position of the legs. —Preceding unsigned comment added by 151.202.105.175 (talk) 14:54, 10 July 2008 (UTC)

Picture is wrong
Part of the article suggests that the lower back does not leave the floor, but the picture quite clearly shows this happening. —Preceding unsigned comment added by Riksweeney (talk • contribs) 13:36, 17 November 2008 (UTC)
 * You beat me to it, I was just coming here to leave the same comment. The image is more of a sit up, isn't it? As instructed (talk) 15:58, 19 November 2008 (UTC)

"Convict Conditioning" is not a reliable source.
There are at least three reasons why this is not a reliable source: 1. Paul Wade is not a real person. Although there are good reasons for publishing a book pseudonymously, we should give such sources less weight than those authored by a respected expert in the field. 2. Dragon Door publishes rubbish. Go to their website and look for yourself. 3. This book cites no sources other than the author's personal opinion and anecdotes. Which could be fine, but we can't verify the veracity of these anecdotes. See point 1.

Normally, I'd add an rs tag to even the most questionably unreliable sources, but this one is just bad, bad, bad. —Preceding unsigned comment added by 68.51.75.50 (talk) 06:44, 16 February 2010 (UTC)

Bicycle crunch redirects here
Bicycle crunch redirects here but there is nothing about it on the page. Which is better, knowingly misleading the reader to a near miss or not misleading the reader? Or perhaps someone could add that content. Joja lozzo  18:55, 14 December 2012 (UTC)

The same with the dragon flag, which was a favored exercise of Bruce Lee. I have no idea why the redirect occurs. While dragon flags target the same muscle group, but is a far different exercise. Its actually more similar to the jackknife than the crunch or sit up anyway (except that the jackknife targets the lower rectus abdominis muscle, while the dragon flag targets the upper).

Back stays of floor?
Article says "in a proper crunch, the lower back stays on the floor". While I agree that's how I'd do a crunch, I don't think that's a universally agreed definition. Perhaps should be rewritten to make clear that's general advice rather than a fact. Reason I came here was that I was reading here about Marine Corps Fitness Test. I thought they'd described the exercise wrong, but quick Google seems to show this is how they are defined in US Marine Corps. See here (much more details about corps strict definition of what counts as crunch) and here for video (For forearms or elbows to touch legs I think most people would be lifting lower back). 92.40.248.215 (talk) 05:30, 20 August 2014 (UTC)
