First, get strong
People who haven't yet done strength training should generally avoid overly task-specific exercises. Instead, they should get strong generally. As Mark Rippetoe puts it:
Strength is the most general adaptation. It is acquired most effectively through exercises that produce the most force against external resistance, and as such is always best trained with five or six basic exercises. The same exercises that are correct for weak football players and lifters are correct for weak volleyball and baseball players, because the best way to get strong will always be the same. Strength is NOT specific, and cannot effectively be acquired through exercises that mimic sports-specific movements, because these movements lack the potential to produce as much force as general barbell exercises, and therefore lack the capacity to make weak athletes as strong as barbell training.
The first place people look for the purpose of rapid general strength gain is generally Starting Strength (the wiki is as quick-and-dirty as possible; the book is the best and most detailed overview on this topic I've ever seen) or StrongLifts (ebook sign-up), which is most appropriate for non-athletes or people who have been inactive for several years. Either of these would be fine.
However, any simple beginner barbell strength program would also be fine. Per Mark Sisson's overview:
The foundation of your routine should be the big compound lifts: squats, deadlifts, presses (bench and overhead), pull-ups, rows, dips, snatches, power cleans, clean and jerks. These engage multiple muscles while triggering your hormonal response systems.
Just steer clear of bodybuilding routines with tons of exercises, machines, and high reps (8-12).
Then, specific strength
After you have some general strength (and not before!), I would recommend focusing on exercises that involve maintaining posture against heavy loads, as well as upper body strength, particularly grip work. To me this means deadlifts, farmer's walks, Turkish get-ups, pull-ups/chin-ups, and presses.
