Take a read of Pavel's "Power to the People"
And if you are interested beyond that, "Strong First" by Pavel and Dan John.
My wife and I have started doing their recommendation in that book of doing two weeks of power to the people (PTTP; 10 reps total of deadlift, followed by 10 reps total of a press-we do dumbell bench press, @80-95% 1RM weight, perfect form, never fail a rep) alternating with two weeks of Program Minimum (Kettlebell swings and turkish get ups).
My wife is a former professional boxer. And not just a crap one, she was in the top few in the world as a bantam weight for a while. And she's intelligent, PhD in biology, etc. We both wish we'd read these books and trained this way back when she was boxing. She would have been #1 no doubt. Free's up lots of time to do other things (eg, boxing practise and technique in her case, in your case, do aerobic workouts, hike), builds up strength without injury, simple.
