Does anyone have any idea how to increase testosterone?
Have you been to a doctor and had your T levels checked, are they low? Would taking supplements work for you? There are prescriptions for that and also stuff over-the-counter. I've been considering it myself, there are a lot of options available on places like Amazon. Joymode seems to be one that is pretty popular right now, at least I'm seeing it in advertisements.
I do it with a chainsaw and an axe. I don't know if there are any studies linking firewood to higher testosterone, but I feel great after busting a cord of wood. I thought vigorous exercise in general was one of the best ways to improve.
