1. You actually have no idea how physically intense yoga actually is, and from that
2. You don't personally consider yoga an athletic pursuit.
As someone who does yoga, I can only tell you that you are categorically incorrect, and based upon that misconception your opinion of it is entirely unfounded. Alas, it seems not only are you unwilling to budge on this misconception, you refuse to entertain the notion you may have misconceptions in the first place. From this, there's simply no point continuing this discussion, but I will say I hope in the future you educate yourself a bit, try it out even, and come back to this conversation in retrospect once you have corrected those misconceptions on your own time.
That said, closing notes:
So, another ad hoc justification for why yoga isn't athletic, is "you have to warm up"? By this logic, no sport or physical activity is athletic as every athlete, or even normal person before exercise (if they know how to actually exercise without incurring self-injury), warms up before physical activity. And even then, the more physically conditioned a person is, they'll have to warm up less and faster. And, if they for whatever reason must engage in physical activity, they can do more without warming up, and at lower risk of injury, due to that conditioning.
And guess what, yogis are no different. I don't have the flexibility, strength, or balance to get into expert positions or do expert sequences, but I can do moderate-difficulty stuff after warming up, and indeed I can go from sitting to doing a Sun Salutation without warming up. Because I've been doing it long enough to have built the strength, flexibility, and balance.
Meanwhile, you still cling to the "XP/dot tax" despite conceding, here, the existence of the complimentary rolls rule. And ignoring the fact, as I stated earlier, you can't swing a dead cat in MtA without hitting an XP break for attributes, abilities, even spheres. Nor paying anything more than lip service to the multitudes of ways to maximize the impact of smaller dice pools, like the "magick enhancing abilities" rule. All of which trivialize this "XP/dot tax" about which you keep harping.
Yet, you've conceded ST's are well within their rights to demand players redistribute dots if they've made unrealistic characters. Just not in this particular case, apparently, in your personal opinion based upon misconceptions I've (pun unintended) bent over backwards to point out. All to justify, and here's the punchline, a character concept -- a yogi that apparently does no other forms of exercise, yet somehow retains a couch potato physicality despite having a guru's expertise, and may or may not have physical primaries to somehow justify a couch potato physicality -- which is such a fringe case it falls squarely into the "unrealistic character" category.
