re: I quit doing cardio

I agree that it’s vital to stay strong as well and resistance train throughout life. But it’s not a zero sum game as you are implying, you can be both strong, fit from a cardio respiratory perspective, and mobile in 4-5 hours a week. About 2 hours for 2 full body workouts and the rest devoted to relatively easy cardio. Anybody doing a PPSA program is spending that much time in the gym so it’s not an extreme amount of time
