BICYCLING magazine's testers were unanimous about SportLegs: It's like a good day in a bottle!" They explained, "SportsLegs contains lactate forms of calcium and magnesium. Taken an hour before exercise, it pre-loads your bloodstream with lactate and tricks your muscles into thinking they don't need to make more - a sneaky way to raise your lactate threshold and boost performance, according to unpublished research by scientists at Ohio's Kent State University." The Denver Post said: "Pop 'em worry-free: Everyone, from the NCAA to an army of top-tier athletes, supports Sportlegs." "SportLegs actually delivers on its promise to reduce fatigue in leg muscles and keep you pushing, pedaling and schussing longer."
