without using your hands/a hand?
Because I can't. You're supposed to be able to.
Ideally I'd like answers not from the super fit gym goers/marathon runners but ordinarily fairly active late 40's? 
What exercises would help does anyone know? (I'm not overweight), was very ill in bed for 5 months 4 years ago and just haven't been the same since and it's really depressing me.
