yoga and slimming down

i was wondering if anyone took or takes yoga and if they really see a difference in their bodies. i mean, i can tell its good for stretching but does it really tone your body? any weight loss?

thanks ladies!

I used to do yoga on a regular basis (before I got lazy ) and I loved it. I worked my way up slowly to power yoga which is tough. It does tone your muscles but slowly. The plank pose is great for your lower stomach but it only tones the muscle underneath. If you want to lose fat I would suggest doing aerobic exercise also (even though you do move more with power yoga).
