As for the nutritionist, what business is it of someone calling themselves a nutritionist, to tell you in what ways or how much or you should exercise? If that was a primary part of their qualification then fine, but to me, a nutritionist's expertise on exercises should extend to personal experience of self teachings, because otherwise they would be qualified to give exercise advice and could give proof of being certified with a reputable company and presumably have a more all encompassing title.
If they are certified with a reputable company in such a qualification then fine, but I would ascertain this before choosing any paid for advice from them. My advice on here always comes free and is optional, so ignoring it is anyones perogative if they so wish, but paid for advice should be clarified, to make sure you are spending wisely.
If the individual is not qualified to give exercise advice, but is stating it is inclusive as part of the fee, it's unethical and you should not use them.
