Icicle- would you be good enough to PM me with any more tips? I am having to do the legs against the wall thing still and I didn't know the correct way you described to pull yourself back up again (hurt my back doing it!)
New Dawn - I will post it here for Otter's benefit as well.
Imagine yourself on your back - legs up the wall...(I also forgot to mention...it's a good idea to put a blanket under your hips so they are slightly raised - this will relieve any pressure on the back and it's a lovely feeling.)
When you come up - the tendancy is to bring your legs forward and raise yourself up with your abdomen muscles. You don't want to do this! Instead bring your legs towards your torso (which is still flat on the floor) - hug them into your chest if you can - if not that's okay. Then just carefully *roll* over to one side. So you are lying on the floor sort of fetal position. With the arm closest to the floor - push up from the floor. All the weight of your body should be in the ARM and not in your lower back or your abdomen.
It's not glamourous - but who cares!!
If you are not sure how it works - start from this position before legs up the wall. Lie down on the floor on your side - tucked up in fetal position and practise getting up only using your arms. If need be - having a chair nearby can help - preferably one without wheels!
This is also an excellent thing to do for PMS and leg aches associated with PMS. Especially important during *that time* to not use the abdomen muscles to bring yourself up!!!
I'm a bit freaky - I do this in airports after long haul flights while waiting for connections!!
