Give this a go, and tell me if you have similar problems to me, or if I'm abit weird...
Stand up (sorry!), feet shoulder width apart and hands by your sides.
Now, unweight one leg and raise that foot up towards your bum, bending at the knee ONLY...don't drop your hips or twist your trunk.
On my right leg, if I reach back slightly I can bring my lower leg high enough for my right hand to get hold of my leg.
On my left side I can't get my foot higher than my knee.
Admittidly I have a ridiculous ape span but my left side seems really crap.
Anyone get similar results?
