Re: What is considered fit?
I've never seen health or wellness as a component of fitness in any definition with components.
I think it's the other way around. Health directly impacst where your arrow lands on the CrossFit wellness-ometer. So, different levels of health must be components of levels of wellness. An american diet and a fitness routine of video games and TV will inevitably lead to sickness so they must be components( more like inactivity). Strict weigh and measure of paleo foods followed by CrossFit or something similar will produce Superwellness, depending on your current level of wellness. All kids raised on the latter will no doubt always be superwell.
Actually health and wellness are the same thing so health is on the same spectum with fitness. Fitness would be superhealthy.
