I'm going to try a couple of situps again. I can't do it lying up, so I try half-sitting. It is really exhausting to get all the heavy mass on your stomach in motion. Then I try to get up from the couch twice. It's very flat, so recently I've always been putting a blanket underneath so that I can sit a few centimeters higher and get up better. So you see getting up once with a blanket and once without, which is really exhausting and doesn't work on the first try. If I didn't have so much strength in my legs, I would certainly not be able to get up on my own without help.
