Cyclist Says: “Sprinters generally have more muscles—just put sprinter Andre Greipel next to Grand Tour winner Alberto Contador and you'll immediately see the difference,” says Peter Sagan, nicknamed the “Tourminator” for his killer performance at the Tour de France last year. The all-around rider, who also excels at sprinting (making him a perfect mix of Contador and Greipel), took home the green jersey at the 2012 Tour and will return this summer to defend his title.
Sagan's crunches: Forget modern-day abs machines. Sagan prefers good old crunches right on the floor. Lie on your back and clasp your arms behind your head. Slowly curl your torso toward your knees, bringing your shoulders four to six inches off the ground (don't sit up). Hold for a few seconds, pressing your lower back into the mat. Return to start. Do 200 to 300 crunches every other day.
