I am 62. The older you get, the harder it gets but all things are possible with consistent effort.
The first thing I do to get in shape for hunting is hunting. I turkey hunt, pheasant hunt, duck hunt, deer hunt and elk hunt when I draw a tag. I am reserving some pheasant hunt dates tomorrow at a local preserve to get my GSP some extra work in. I will hopefully get in 4 or 5 hunts in before March 31st. Just put in for an out of state turkey hunt in April too. I camp when I turkey hunt to practice using my tents and stove.
- lifting weights 2-3 times a week at a gym and not old man lifting. I do one day upper and one day lower. I will add a 3rd day of lifting if weather limits my walking. Really important if you plan on carrying out meat. Covid put a halt to this last year but I am rejoining the gym. I should draw an elk tag this year.
- walking. I try to do 3 to 5 miles a day. I walk my hunting dogs daily and frequently. Sometimes I will add a late day climb or an extra 2.5 mile walk. I have a weighted pack I use to change it up, some days. Get a hunting dog. Every guy over 60 should have a hunting dog.
- diet. I have myself on a relatively strict diet right now. My dad was a wrestling coach so I know a few things about diets and cutting weight. It sucks. 150 calories in the morning. 150-200 calories at lunch. I pretty much eat the exact same thing every day for breakfast and lunch. Healthy dinner with lots of veg. Things like fish and chicken. No bread, sugar, candy, sweets, pizza, alcohol etc., No late night meals. I try to stay under 1500 calories. Low carbs. Low sugar. Water is your friend.
