So, I don't want to come across as a trump apologist, but there's actually some logic here.
I'm a fairly athletic guy, 25 years old. About a year ago, I was in the gym 6 days a week, each session lasting about an hour to an hour and a half. Each session would start with 10-15 minutes on the treadmill, usually with incline, followed by workouts that targeted two muscle groups per day. One day per week would be a rest day. This was accompanied by a well planned 3000-3500 Cal. diet. Back when I was in college, this sort of routine was fairly easy to handle. But, with every year after college, it became harder and harder to maintain. Frankly, eight hours of sleep was not enough for me to recover from fatigue and there weren't enough hours in the day for me to actually have a social life. So, subsequently, I'd have low productivity at work and my personal relationships foundered. In that sense, I can definitely see where this statement comes from:
the human body [has a] finite amount of energy, which exercise only depleted
It certainly felt like that for me, back in July of 2016, when I ended up taking a log break from working out.
With that being said. Not getting any exercise is pretty sucky. You feel stale. You're more prone to negative thoughts. Your body shape typically starts to slide down hill. You're even more prone to negativity. Your general fitness goes down and the set of stairs you didn't notice before leaves you almost winded - not to the point that others notice, but enough for you to feel very uncomfortable. And you're even more prone to negativity. So, these days, I just go to the gym three times a week. I start with a mile on the treadmill, no incline, and do a fairly casual full body routine. All in all, it takes me 45 minute. Then I might take a run outside or go for a good bike ride once a week. Doing that for a couple of months, along with a good diet, helped to take care of all the sucky stuff described above and, frankly, give me a more energetic and enthusiastic attitude.
Not everyone needs to take on bodybuilding routines, or any kind of dedicated athletic training, in order to see benefits from exercise. In fact, most people will not see benefits from training like serious athletes, while trying to make time for other things in life. Not understanding this definitely bit me in the ass, and I could imagine that it's where that passage about Trump's ridiculous views of exercise come from.
I will add, though, people who manage large amounts of money seem to be disproportionately prone to weird beliefs about health. Steve Jobs is certainly a possible example of this. But Aristotle Onassis is probably the best source of almost wholesome advice that ranges from mostly to absolutely terrible for your health:
Don't worry about your physical shortcomings. I am no Greek god. Don't get too much sleep and don't tell anybody your troubles. Appearances count: Get a sun lamp to keep you looking as though you have just come back from somewhere expensive: maintain an elegant address even if you have to live in the attic. Never nickel when short of cash. Borrow big, but always repay promptly.
Or
Don’t sleep too much. If you sleep 3 hours less each night for a year, you will have an extra month and a half to succeed in.
Just to recap - I'm not a member of any circle jerk. If anything, recent events have made my life quite annoying, being a Russian guy in the US. I'm just explaining where Trump's logic comes from and saying gross misunderstandings about health seem to be a somewhat common problem among folks who have tons and tons of money.
