Hahaha, that's amazing!
Honestly though, if you look at long-term healthcare costs, anything that motivates you to exercise NOW (and do so consistently) will create health benefits LATER, which will save you money down the road because your body will be in much better shape as you go older than it would if you were to NOT exercise. Not to mention that the cost ($2,245 plus $39/mo = $468/yr for the service) really isn't that bad,
in perspective, when compared to hiring a personal trainer in meatspace (which goes for $300/mo at my local gym for two sessions a week, or $3,600/yr - which is less than the bike with the first year of service - although PT prices vary
widely). Granted, pedaling a stationary bike you already have at home is free, but that's not the point if you're struggling with self-motivation!
Your body is either a prison or a freedom vehicle, depending on how you treat it (barring any unsolvable medical issues). If you struggle with motivating yourself to exercise on your own & aren't willing to spend any time, money, or effort on getting help, then that simply shows your level of commitment. And sure, we can argue financial limitations, but that's kind of a crock too - you can pick up a used exercise bike for $50 on Craigslist just about anywhere (or probably for free, if your buddy has one & you trade him a pizza & pick it up for him, as he's probably using it as a clothes hanger, hahaha), there are tons of side hustles like Uber Eats delivery available...where there's a will, there's a way, and where there's not, there's an excuse.
I understand the dad's perspective, because it's a truckload of money up-front for an exercise machine, plus a high monthly fee for service (which could get you subscriptions Netflix, Hulu, Spotify, and Prime instead! hahaha). However, your health is not a frivolous thing, as exercise affects your mood, your weight affects your self-esteem, and your overall fitness affects your well-being long-term. If getting plugged into a pay-for network motivates you to actually do it, then I'd argue that, if it's within budget, then it's money well-spent. Versus say, cocaine, which is kind of the opposite idea of exercising, hahaha.
