The cause of the burning sensation you feel in your muscles while exercising is twofold: it is partly due to the build up of lactic acid, but it is also due to a lack of oxygen. 1  You can ameliorate this by paying close attention to your breathing while you exercise.
| License Photo. NEW YORK, June 18 (UPI) -- Heading into Thursday, the highest level the Nasdaq had ever reached was 5,132.52 -- a mark set in March 2000. At the close of trading, the composite was nearly a half-point higher -- and good for a new all-time record.
Based on these numbers, it's not hard to see why iRobot's stock is up a healthy 7% today. But that's only with the benefit of sleeping on the report. The stock price spiked as high as $22.41 per share overnight, for a stunning 17% increase. Sadly, that didn't last into the market's regular trading hours. If you expected that mirage to last, you clearly haven't studied after-market moves much.
