But really, after a certain point, MAKING time to exercise is a bit like brushing your teeth, doing your taxes, managing your finances, and showering regularly: It's something you have to do as an adult or face the consequences.
Does exercise give you more energy? Does exercise help with depression? Is exercise REQUIRED to be a healthy individual? Over and over again the research has shown the answer is a resounding YES.
Personally, I like Jocko Willink's advice about gyms: Home gyms are essential. They are much less hassle. You don't have to pack a bag, commute to the gym, deal with the other gym people, shower, commute home, and collapse after a two hour gym adventure. You can just throw on your gym clothing, walk into your garage, throw some music or a podcast on the radio, and get to work.
