She should take notes from Laurie Henes because that has been working well for her. I like Natalie and Parker, and it's been interesting to see how the "less is more" approach has paid off in dividends for them, since it has been maligned so much in the past.
With that being said, my understanding is that they have followed that approach because they have suffered injuries in the past from doing too much, so this approach is what works for them specifically.
I think we're past the point where we can criticize Tuohy for doing too much training (in our outsider's opinion). Whatever she's been doing is working for her.
