Is there a benefit to doing crunches over sit-ups?

Are situps considered a good core workout?

Short answer: No. As an exercise they are sub-par, and as a workout they don't even qualify. But we can tweak it, and add to it, in order to reach our goals. I agree with the article author's decision ...

How much weight am I lifting doing sit-ups?

Well, one thing you should note is that 64% is the standard percentage of the upper-body compared to the entire body. On the other hand, a sit-up is pretty hard to measure. A body-builder who has ...

Max reps, boredom and carpet-burn

Crunches overdevelop the top 4 ( or crown ) of your 8 pack abdominal muscles, unless you are compensating by doing a lot of lower abdominal exercises. A sit up is also not the best abdominal exercise ...

What are the benefits or drawbacks of full sit ups vs crunches?

More muscles are used in a sit up but crunches seem to focus on the abdominal muscles more. For myself I can do 2-3 times as many crunches, and always do some crunches after sit ups to continue ...

Why cant I do any situps without someone holding my feet

It is possible that you're using your leg muscles to push yourself up in the sit-ups. I know I had that problem at one point. If you're feeling tension in your legs while doing the sit-ups, there's a ...

Are there any benefits to using a sit-up bench for sit-ups?

The key difference between a floor and a bench sit-up is that the latter affords us the ability to alter our load profile. In a sit-up from the floor, the greatest load on the hip flexors and ...

Planks vs. Sit-ups / crunches

Since building a sixpack will require some muscle growth, I'd argue that neither are effective. You'll be at a point where you can do dozens of sit-ups very quickly, which might be fine for the ...

I can't do curl ups without someone holding my feet down?

No matter how hard I try, I just can't lift my back up in sit-ups

sit-ups form: difference between straight back/shoulders back, vs. hunched
