So how does one avoid a muffin top?
To do the move properly, get into the above position. You don't need a ball.. you should actually use your hands to hold yourself up. Tuck your hips - meaning that motion of tilting your hips under, as if to suck in your stomach and lean forward.. that feeling of your hips tucking in is what you want throughout this exercise. ove you back knee far away from the line of your front leg so that it is truly behind you and in the shape of a weird looking human pretzel. Now, you can do an assortment of exercises - including lifting your knee, or pushing it back, or just keeping it up. You will feel this in your obliques almost immediately!
For the lazy, just do the twist so your obliques feel it.... do the twist!!!
4) Try on jeans and make sure they aren't so tight that your muffin top shows. Bigger jeans that fit appropriately will do wonders.
5) Love your body and listen to the 4 rules above and avoid muffin top!!
