I just realized I have been doing situps wrong for years. YEARS.
I just started working out again, after a multi-year hiatus brought on by drinking, self loathing, early onset midlife crisis (I'm planning to live to 150, so this is some bullshit here getting all down on myself at 37) and a bad case of the phuketts (Phukett, I'll work out tomorrow...)
Every time I've done situps, I have hooked my feet under something. The sofa, a heavy table, had someone hold my feet/ankles down.
NO. BAD. WRONG. HOT. DO NOT DO THIS.
This lets me flex my feet, and pull with my legs/hips. This is BAD. It does not isolate my abs, it involves the muscles in my legs and hips. Instead, what I now do is have a partner grab behind my calves, OR I hook my legs over the Iron Gym (pull up bar thingy) and I keep my feet on the floor, pushing down for all I'm worth (about $1.80 in change). then I s-l-o-w-l-y try to sit up.
Not gonna happen. Not yet, anyway.
Now, the abs get isolated, the hips aren't helping, and there is no way I can even get started without a little help, as my poor, underdeveloped one pack tries to haul the majority of my bloated, wasted carcass up.
I learned how to do it this way by reading up on
Pavel Tsatsouline. Sure, he's a crazy assed ex-soviet. Who better to re-educate my atrophied musculature into shape?
