When We Were Thin
Who better to take on the epidemic of overweight Americans than the most charismatic heavyweight in history? Muhammad Ali has loaned one of his better nicknames, G.O.A.T. ("Greatest of All Time"), to a line of nutritious snack foods aimed at the nation's increasingly pudgy young adults.

XX Games
From the guns of biathlon to the sequins of figure skating, one thing remains constant in winter sports: What's good for the goose is good for the gander—except in ski jumping, still the only winter Olympic event without a women's division. But with the International Ski Federation adding WOMEN"S SKI JUMPING to the 2009 Nordic World Championships, the 2010 Olympics will likely follow suit, giving women just as many opportunities to toil in anonymity as the men have. In anticipation, the U.S. Ski Team has named its first women's ski-jumping squad, which will open this winter season as the overall favorite at the Continental Cup in Väler, Norway, December 13.

The 63-mile route (39 miles for women) will take competitors through the Czech Republic and Germany before finishing with a grueling climb up Italy's Alpe Cermis. December 29–January 7; fis-ski.com
