my gym teacher makes us do it without stuff to hold our feet

[lova56]

using weights to hold down is one of the best ways to hurt your lower back, especially without proper know how, ability, or supervision. The weight might be good for those who are returnees getting back into shape but know how and what they are doing. Otherwise its best to use and develope your own strength and discipline. What will you do without the weights doing the work you should be doing.

mr thomasp

he doing the rhigt way

... No.2, this exercise does, as robbty18 rightly stated, engage the hip flexors when the spine flexes past approximately 30 degrees, taking away the influence of the rectus abdominis. Doing the crunch exercise alone tends to hold more benefits than this exercise.

[Greaves666]

Please tell me how this is effecting the core muscles?

In fact please tell me if you know the what the core muscles are?

No.1, orthodox sit-ups primarily activate the rectus abdominis and have very little impact upon the core muscles (i.e. transverse abdominis, internal obliques, psoas and multifidus muscles)....

[robbty18]

Way to work those hip flexors. Don't hold the feet down, "expert."

[thomaspettit85]

Yeah this is actually true...

If you support your feet and bend at the hips you work the hip flexors. Keeping your knees bent, feet flat and doing crunches is much better as your hips dont move and you abdominals have to do the work contracting. Bending at the waist is very ineffective for the abs. So I don't know why people are giving this the thumbs down.....

I can do 50 situps when someone is holding my ankle, But i cannot do one damn un-assisted situp shown in this video. Any advice?

[Hydrot]

u balance ur feet by using ur heels of your foot but he's using weights to hold his self down if u notice

[maniax342002]

I know. But when i try to do it without anyone holding my ankles, my feet come up. I cant hold them down. Please Help.

[flameorange]

[Harritan]

stop doing them, its probably because ur doing them wrong

[snoobl]

Ok, good video.

But he doesnt look so sporty..

[ge1org1e]

I have no idea what you mean

[snoobl]

i mean he looks boney!

but he shows how situps work.

[Kentuckybred]

Crunches and situps work different areas of the abdominals. The important thing is to do what is most comfortable. A crunch is not a complete sit up..Crunches are short bursts while situps are completely up and down. Just remember to do what is most comfortable...Like he says, if situps hurt your back dont do them, do crunches..and vice versa.

[gince]

Good video. Bur I have a question. Is it better to lay back on the floor or not touching it?

[Michaelanchio]

In my opinion not touching it, You dont have to make big movements

[gatocandy]

im confused wats the difference ?? can someone please explain!!

[ah3133]

I remember my gym teacher from back in the day saying something about the lower back to be careful about, but couldn't remember. This video was helpful, thanks :)
