I do LISS Cardio everyday with my current stack to protect my heart.. I do MiSS rarely and almost never HITT cardio unless playing a random sport while loaded to protect my heart..Your cardio level should be locked in before your Cycle IMO and just keep the blood flowing to maintain.. I’m 48 and that’s how I do it.. I even drop jump roping on cycle.. my heart definitely doesn’t need to get harder..lol
