After a three-day affair marking his wedding to Camila Alves (now Camila McConaughey!), it was back to work for Matthew McConaughey – working out, that is.
But McConaughey, 42, who tied the knot in a sunset ceremony Saturday on the couple’s sprawling Austin, Texas, property, rocked his gym attire with a very special accessory Monday: his wedding ring.
It was the first time the newlywed has been photographed since his nuptials, which guests – including their their two kids, Levi, who turns 4 next month, and daughter Vida, 2½ – celebrated throughout the weekend.
Activities ranged from lounging in hammocks and playing lawn games to sleeping in luxury tents pitched across the property for the occasion.
And his sweat-soaked attire was a little different than the look he sported Saturday during the after-dusk ceremony.
“Matthew looked so handsome – like an old Hollywood movie star,” a guest told PEOPLE of McConaughey, who donned a three-piece black Dolce & Gabbana tuxedo alongside his wife, “glowing and beautiful” in a gown by a favorite Brazilian designer.
For an inside look at Matthew and Camila’s wedding weekend, with photos and you-are-there details, pick up next week’s issue – with a first-look on PEOPLE.com on Wednesday at 8 a.m.!
