What's the Most Efficient Form of Exercise?
This podcast has a lot going for it.
- it recommend squatting. Yes, the squat, because for longevity, a great indicator of your ability to fend for yourself is your ability to get up and sit down unassisted.
- what the most efficient form of exercise is, depends on what your goal is. You need to know what you want to accomplish before you can start to accomplish it.
- it gets a little into the new trendy thing, short but intense cardio. Which isn't bad, because on a pure time-to-results grade, it's excellent. It won't do everything and it's not the best for everything, but it's a good way to start. Look into HIIT.
- you have to like what you're doing, or you won't actually keep doing it.
