What’s your approach to cardio training? For me it’s
> 2 days run 3-4 miles,
> 1 day 4on4offx4 HIIT on stationary bike or elliptical (for heart rate monitor
> 1 day high intensity sport
It’s not as much as a real endurance athlete but who has time for 10 hours of zone 2

Daily reminder if you don’t play sports then you are not fit
