Cardio for me is 5 x 30 offseason for health benefits and maxes at 5 x 60 in prep. Starts on incline treadmill and moves to stairs. Incline on treadmill and speed on stairs increases every session. Will usually pull down to 5 x 20-30 by 2 or 3 weeks out as I’ll be ready early and can cruise in. I do all cardio fasted as I think there’s a synergistic effect when using yohimbine, GH and clen.
Most people I know work up to 5-6x a week 60-90 minutes until peak week where it gets cut. Obviously this stuff varies drastically based on need though.
I like this approach. I'm not into competing, but of course I'm trying to keep (or get) my heart into better condition.
In the spring, summer, fall months, I love it because we do it outside. 1-hour walk per day, a fast-ish pace, hills all over, etc. Actually have to stop/rest a couple of times.
(Mainly for my back locking up, trying to improve that as well).
Indoor cardio, I try to get thru it. (When cold weather comes (right about now). Trying to at least do 3-4 sessions a week on treadmill at home. (30-mins).
Hopefully its just enough to maintain until nicer weather gets here in Spring. The treadmill and similar machines really bore the &*&* out of me...
