Phil Mickelson has impressed the fitness world in recent years with his calves, which have constantly gone viral on social media.
It turns out Mickelson's body transformation includes more than just his leg muscles.
Mickelson's sister, Tina, shared a shirtless photo of her brother at the beach on Twitter late on Tuesday night.
"Family beach day. Looks like calves are working their way up," she wrote.
Hey, good for Phil. He's looking good at age 49.
"Love you sis. Such a fun day seeing everyone. FYI ,those weird bumps on the side of my stomach we’ve never seen before, Doc called them obliques and said it’s nothing to worry about," he responded.
Mickelson has become much more fitness-focused in recent years. He did a six-day fast before The Open in Northern Ireland, consuming only coffee and water.
It hasn't resulted in any big wins - yet - but he's certainly becoming a bigger presence on social media.
