THE BIKE MESSENGER
NAME: Sam Paul
WEIGHT: 112 pounds
WORKOUT ROUTINE: Bikes for six hours a day, four days a week. Does 200 sit-ups daily for added core strengthening.
BODY COMPOSITION: 15.6 percent body fat with a BMI of 20.5.
AEROBIC CAPACITY: VO2 Max of 50, which puts her in the 95th percentile for women between the ages of 20 and 29.
MUSCULAR STRENGTH: 52 crunches and 30 push-ups.
POWER: 13.5-inch vertical jump.
FLEXIBILITY: 9.8 inches on the sit-and-reach test.
THE VERDICT: For those of us with crazy-long office hours (or just a lot of excuses), here's a novel idea for an intense workout: Ride a bike. Paul's riding routine has resulted in lean muscle mass and an incredible aerobic capacity. (Watch out, Lance Armstrong!) The only catch? Tightness in the back of the legs requires extra stretching sessions off your wheels.
