I am looking forward to my first elk hunting trip in Colorado in September. I am 44 years old, weigh 170-175 at 5'7". My biggest concern is belly fat and I don't practice a great diet sometimes, as my wife loves to cook, and I love to eat. But I do at least try to get some vigorious training, here's what an average week looks like,when I am NOT having to travel 1,000+ miles per week with my job...
I try to incorporate good old fashioned circuit training 2-3 times per week at the gym as follows:
Bench Press - 140X12 set 1, 210x8 set 2, then back to 140x12 (3 sets with only 2-30 seconds rest between sets)
Bicep Curls - 25x12 (each arm) 2 sets
Seated Row - 130-140 X 2 sets
Lat Pulldown - 110 X 2 sets
Tricep Extensions - 130x2 sets
Pull-Ups - 2 sets of 10-12 or max out
Push-Ups - 2 set of 20 or max out
Core moves - 2 sets of back extension, leg raises, etc.
Standing Flys - 100x2 sets
Seated Bench Press - 170 x 2 sets
Crunches - 2 sets of 25 Bicycle crunch 25X2
Seated trunk twists - with 10 lbs medicine ball x 100
I usually compliment this with a 1-2 mile run for cardio conditioning from my house to the gym and back, this also helps me get warmed up.
A couple of days per week I try to run 5-6 miles at about a 9-minute clip. Remember to stretch AFTER all work-out, hitting the major muscle groups that you are working out that day!
I have blended some of my old Marine Corps boot camp training with some of the new stuff I learned from a personal trainer I hired for a few sessions (well worth the $$ he charged me).

Think that several folks have hit the head of the nail that you need to be CONSISTENT and try to get something that you ENJOY and will stick with on an ongoing basis.
