Oh my goodness, I never have because I've always been on the heavier side BUT since end of October I've currently dropped 30 lbs.
All due to the right way to eat and working out like there is NO tomorrow. I just decided that I wanted to change myself for health concerns etc.
So I actually don't do basic crunches at all and I haven't done them ONCE during this change. It's partly due to the fact that they won't benefit me at this point.
I have to work HARD on them. I LOVE using the exercise ball for multiple tummy exercises. Well I love and HATE them. I mean they are a solid workout and you really feel these exercises and it's not much fun in the beginning because of the sore factor but now I strive for that soreness because I KNOW it's working.
My Ileum body fat measurement (the portion above the hip bone) went from 55 to 25 so far!!!! =)
Here are some of the core exercises that I do.
Jackknife with ball
Kneeling roll out with ball
Modified plank
Ball curl
Oblique crunches (but ON the ball!)
I say some because I can't remember what the other ones are called lol
These are awesome to do and you can do them at home as well! I'll figure out what the other exercises are called if your curious to know them. =)
I WILL have a fit healthy body! (one daaayyyyyy fo shooo) lol
