You can be disabled and still health conscious. Health consciousness is about maximizing your body's health potential - not sidestepping physical realities such as a disabilities. In fact I would say it is probably more important for disabled people to be health conscious than able bodied people - at least there are probably worse health outcomes for disabled people who are also not health conscious vs abled bodied people.
This company does seem really stupid though: I love the end of their pitch where they say 'We believe winners have always won', so submit a brag sheet about everything you've ever done in your life.
