Careful. You can’t just replace cardio with loaded carries… loaded carries are a strength movement which does tax the muscles and nervous system, cardio does not.
While I’m all for using loaded carries as your cardio, you must but careful adding it at first. The prowler is less of a problem as it is less neurologically demanding than carries and you can use a moderate load that doesn’t tax the muscles too much. Harder to do with carries while still being effective.
