Golf is not the first game that comes to mind when one thinks of core muscle development, but maybe it should be. The L.A. Times reports on the workout regimen of Natalie Gulbis, which includes a one and a half hour session at least five times a week. Ready? Here we go: The paper reports that Gulbis’ workout ncludes 15 to 20 minutes of cardio, such as
active stretches and lunges, 30 to 40 minutes of lifting  bicep curls
with 20-pound weights and bench presses (100 pounds). Between lifts,
she does crunches  and works a stability ball for balance and core
strength. She also does explosive exercise, such as very fast push-ups
and jumping jacks to build endurance and agility. For variety, she’ll
take a kickboxing, hip-hop or Pilates class.
