Why then do I doubt that you are in ‘top physical shape?’

Maybe because my GF is extremely athletic and incredibly fast?? She does marathons, triathlons and CrossFit events on a regular basis. Zero body fat.

I run with her but more interested in lifting.

Then I surmise that your cardio conditioning is subpar.

I’m a distance runner myself. If you’re lifting, that won’t help you run.

If your gf has “zero body fat”....she is not a girl
