The May 2011 issue of Yoga Journal has a great article on core strength ("beneath the surface"). Â I pretty much do yoga at home with videos, plus some of these routines I find in this magazine. Â We don't have classes nearby. Â What i liked about this particular article was the focus on keeping the psoas muscle from tightening. Â It felt great! Â We get our copies via the library.
   One easy idea I like from yoga is the lock--udianda(sp?) banda--where the abdomen is pulled inwards.  You probably know it: from a wide stance, put hands on knees, exhale, while breath is out lock chin and pull abdomen into your spine.  Hold, or drop and pull up the abdomen repeatedly until the next breath.  Before inhaling, relax the abdomen completely, then inhale.  Repeat.  I found doing this just once or twice a day was enough to feel some strengthening.
   I also liked the video "Yoga Burn" with Rodney Yee, and, surprisingly, "ABC Yoga Kids" with Marsha Wenig is great for back and abs.  It's my favorite in the series because I really feel tall and strong after it, even though it's for kids.
   I find that having the occasional "soup day" makes a good cleanse (I WILL NOT FAST!) that has instant effects on both my weight and my gut.  I only do these (just one day only) when I need to reset my appetite and feel a little better about how I look.
   GOOD LUCK!
