We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I was asked for a list of some good HIIT cardiac stressors. The theory, likely correct, is that these anaerobic or borderline-anaerobic stressors build heart muscle and heart vasculature such that physical endurance and energy are improved, along with the chance of surviving one's first or second heart attack.
Here's a partial list of good ones for interval exertions (30-60 seconds, 60-120 seconds slow between):
- Speed jump rope - Mountain-climbers - Rower sprints - Treadmill running sprints - Swim sprints - Stairmaster sprints - Step-ups with hand weights - Box jumps - Heavy ball throws and smashes - Combat bike sprints - Sled pushes and pulls - Ski Erg sprints
I think it's best to do a mix of these to prevent adaptation and efficiency.
Powerlifts also are good heart stressors as we all can tell from the dizziness after a few reps of heavy, but I am not convinced that it's enough to do the job. A reminder to women that, after menopause, heart disease quickly catches up to that of men.
running sprints don't need to be on a treadmill, of course, but you can do them outside. Much more enjoyable, and you can push to your limit without worrying about getting thrown off the machine if you can't keep up! Track, grass field at the local park, beach, anywhere.
Or if you have a decent hill nearby, run up hard and walk down.
