NAME: Keisher "Fire" McLeod-Wells
WEIGHT: 109 pounds
WORKOUT ROUTINE: Strength-trains for two to three hours a day, five days a week. Alternates between jumping rope, shadowboxing with 2-pound weights, and sparring in the ring for 45 minutes.
BODY COMPOSITION: 14 percent body fat with a BMI of 16.6.
AEROBIC CAPACITY: VO2 Max of 48, which puts her in the 97th percentile for women between the ages of 30 and 39.
MUSCULAR STRENGTH: 50 crunches and 40 push-ups.
POWER: 14-inch vertical jump.
FLEXIBILITY: 7.5 inches on the sit-and-reach test.
THE VERDICT: If mellow yoga classes aren't for you, try McLeod-Wells' circuit-style boxing routine with endurance- and muscle-building exercises like jumping rope and shadowboxing. Plus, arm-sculpting jabbing sessions result in stellar upper-body strength, making tasks like carrying groceries and carting heavy loads of laundry a breeze. Flexibility can be deficient here, so adding Pilates or some other stretch-oriented class would boost your workouts in the ring.
