Anything that either causes your ribcage to curl down towards your pelvis, or or pelvis to curl up towards the ribcage will work primarily the abdominals, with support from the obliques and hip flexors. If the spinal column doesn't flex, you're not really using the abdominals except as in support. By that I mean that if by leg raises you mean keeping your ...
First let's see how the exercises square up on the whole. Studies have been performed regarding the EMG (electromyography) activity for various abdominal muscles in a variety of exercises. You will find the results for the exercises in stimulation of the rectus abdominis and obliques, relative to the traditional crunch, in this Wikipedia section: ...
From personal experience, albeit without professional experience or references to back it up, crunches tend to feel like they're only really working the front of the abdomen, while leg lifts always feel like they engage more of the sides, possibly due to differences of stability and how far off of straight legs can go versus the torso.

Let's look at the two most prominent nutrients found in lemons that could play a role. These are vitamin C, and citric acid. Lemons are rich in vitamin C. One fruit will deliver from 50% to 75% of the daily recommended amount, depending on the size of the lemon. That's nice, because it is an essential nutrient; humans can't synthesize it in their bodies. ...
Pull-push question probably should be separated from here, so I'm sticking with the abs. Ab-wheels are great, and for anyone that's in pretty top notch shape with good shoulders and good body mechanics, I'd recommend them. But they're an advanced exercise and it's easy to hurt your back, shoulders, and wrists if you're not there yet. No need to jump the ...
