Studies show that the more people watch TV (and maybe computer etc as well), the more likely they are to be obese, and even die!
But, use it to your advantage! I got pumped up watching the dramatic finish by Northug in the Olympic men’s 50 km cross-country ski race. I then got my music going, and got on the elliptical. I did the elliptical for 30 min while watching the 4th quarter of the Spurs and Suns game – Stoudamire & Nash / Ginobili & Duncan!
I never was and never will be anything like those guys - but it made for a fun workout!
