Exercise works in a more better way as it takes all the body parts to work and burn calories,all organs function in more better and healthy way ,it increases blood circulation from brains to toe....choose whatever mode of exercise u want,jogging,yoga,aerobics etc etc you will find million dollar glow on your face after exercising rather to go on crash dieting ,in which you may develop nutrional deficiency and may caught diseases too....so shun all the moods of laziness and workout only for 30 minutes daily and see yourself with more positive feelings through out the day!!!its tested and well proved too! dont believe...try yourself...
