not with chess. How about Chess Reading?
Apart from boxing, what else would combine well with chess?
Sort:
Oldest
Kung Fu Piano. 
Chess and drinking ?
Acupuncture and darts ?
Truck pulling and stamp collecting ?
Finger drumming
(Belly Dancer not included)
When its your turn to move, you click your fingers--ching ching. LOL. Can you imagine a room full of tournament people all going, ching, ching
How about playing Checkers and Chess at the same time?
2 simultaneous games of chess.
first choice: Gruyère soup and grilled wild sturgeon with herbs.
second choice: Arkanoid with five pitchers of draft beer and a few pretty birds to play and drink with.
might work well with golf. there are many similarities between the games, including that you have time to contemplate your next move; and position is important. Strategy. with golf you have to execute physically. both are very mental, require intense focus; also, people not athletic enough to play sports (like me) can play chess, and golf requires less athleticism than most sports.
Chess and boxing eh!

True - I like golf too. 
You could always have a mini-golf version for the kids.
Definitely Table Tennis
WATER it's the best companion for chess

I play chess at chess.com while using a step machine at my gym for the hour I am on the machine, as I am doing as I type 😎
Definitely football, soccer. Positional superiorities, tactics, lecture of the position, weak squares, diagonals. It suits very well strategically

I believe many strong chess players also are decent at things like poker and other casino card games.
Jujutsu, especially grappling. It requires patience, persistence, positional anaylsis, skill, courage, and sometimes a little recklessness.
How about Chess Tennis? I'd like to see that!
