Leaving aside concerns about building strength - Are there health benefits to high rep work? I've read about people dropping fat on such a program. How does it affect the heart, insulin sensitivity, immune function, etc?
It's cardio.
Depending on the tempo and intensity, it's probably similar to walking up flights of stairs.
I would expect the usual impact on heart, insulin, etc, as moderately vigorous cardio.
I would expect it to be not as good as rowing or cross-country skiing, as air squats aren't using both the upper and lower body as those exercises do.
