Check out Jameis Winston's new beach bod, 20 pounds slimmer

The father of Tampa Bay Buccaneers quarterback Jameis Winston told ESPN.com that Winston has lost 20 pounds in an intense summer workout with noted trainer Tim Grover.

Grover posted the famous before and after pics of his son from the “wow, look at that gut” pic of January 2015 and this year’s “dude is in shape!” version.

Grover, who has worked Michael Jordan and other elite athletes, appears to have helped Winston slim down — especially in the midsection — quite considerably.

In addition, Jameis reportedly has changed his eating habits, too, cutting out potato chips and other high-fat snacks and refraining from after 7 p.m, per his dad.

Here’s more of what Winston has been up to this summer:

Winston is vacationing in Turks and Caicos and hasn’t been afraid to show off his new physique there on social media, either.

Winston will report to training camp with the rest of the Bucs’ veterans on July 27, and it appears he’ll be in great shape when he does.
