Photos: Lexi Thompson And LPGA Stars Get Golf Strong\nExclusive photos from our May 2015 Fitness & Power Issue of Lexi Thompson, Michelle Wie, Cheyenne Woods and Stacy Lewis\nEditor's Letter: Mea Culpa, Ladies | Video: Watch Lexi beat the crap out of some unsuspecting bro\nLexi Thompson is the third consecutive woman to be on the cover of our May fitness issue. She joins Holly Sonders (2013) and Paulina Gretzky (2014).\n"(Trainer Craig Slaunwhite) was all about strengthening my core. I basically live standing on a Bosu ball," Lexi Thompson says, referring to the inflatable, unstable, hemispherical platform. "Exercises like this help build the strength so you can swing within yourself. A lot of amateurs over-swing because they're not strong enough to stay in control."\n"I don't do weighted machines," Thompson says. "There's no sense in a golfer risking putting that much stress on the joints."\n"Growing up I always wanted to try to outdrive my older brothers. Playing with them definitely made me the player that I am."\n"I definitely think I can get longer. There are a hidden few yards here and there for sure. It's all about learning what muscles I need to work on to get that extra distance out of my body."\n\n"I love it," Lexi says of boxing. "Punching teaches you to get power with your whole body. And it gets the anger out. Like the golf course, you can get in your own little world where nothing matters."\n\n"Gaining strength in the right parts of my body has enabled me to swing more consistently and I'm able to move my hips better," Wie says.\n"Women have the great ability to create torque because they can turn better than men, and that's why you see a lot of long swings on the LPGA Tour," Dave Phillips of the Titleist Performance Institute says. "If a woman can get a really strong lower body, she can develop speed just as quick as a man."\n\n"Doesn't matter if you're a man or woman," David Leadbetter says. "As you age, your flexibility might lessen, although your strength increases. You end up generating power in a different way."\n"I just love being outside, the adrenaline, and knowing that I'm fit," Woods says.\n"Flexibility and endurance are huge in pro golf. You have to make sure your body can stand up in the heat of playing five times a week."\n"It's nice to be mistaken as a track athlete," Woods laughs. "People are usually like, 'Wow, I didn't know golfers ran.' It's cool to show that golfers are athletes, too."\n"She sets the bar for everybody else here, guys included," trainer Dave Donatucci says of Stacy Lewis. "She's never without her logbook, and she's always trying to lift more weight."\n"I work out six days a week, whether I'm at home or on he road," Lewis says. "As I've seen my body change, I've seen my game change."\nWatch Lexi Thompson beat the crap out of some unsuspecting bro.
