there are two ways to do a sit-up:
- the easy way, which is the way you probably do it
- and the hard way, which involves
- maintaining posture of straight back, with shoulders in their proper position
- as if you were standing confidently, unafraid, in front of an audience, perhaps as if you were finishing an opera, arms extended, embracing the world.
I've been doing them wrong my whole life.
I'm wondering what sort of difference I can expect in my abdomen. Which affects what muscles differently?
