Having brawn; muscular, strong, or well-developed in muscles.
From Old Norse 'braun' meaning 'meat' or 'flesh,' 'brawn' originally referred to the meat of a boar, then generalized to mean muscle or muscular strength in the 15th century.
The British still make 'brawn' as a food—a jellied meat dish—so when you call someone 'well-brawn'd,' you're basically saying they're made of sturdy meat, which sounds funny but is actually an ancient compliment.
