I've been waking up early to do fasted cardio for nearly a decade now. Almost always incline walking on a treadmill, with heartrate at 115-120 (resting HR usually in low 60s). However, it feels like I haven't progressed in years as far as my cardiovascular fitness, and with my recent bloodwork having high cholesterol (not using any AAS or AIs near bloodwork, strict diet), I wonder if I need to increase intensity, or maybe add some higher intensity cardio on off days from lifting.
What do you guys recommend/do yourselves for cardio? My main concern is overdoing it, and detracting from weight lifting. Appreciate your input.
