I got back on my little po today for the first time in AGES, and he was very very good

.
We just had 20mins in walk and trot in the school but I am so glad to be back on!
I have decided 2011 is Bob's year for doing stuff, as he turned 6 at the end of last summer and is now a grown up. He will be doing much more schooling now in preperation for doing some dressage (that is what I bought him for, after all!).
However, happy hacking for the last year and then hardly riding at all for the last 2-3 months has taken its toll and my body isnt doing as it is told :p. Strangest thing so far is that my right leg, which has always been the one I am weaker in, is really quite uncomfortable when riding :s. Its the front of my shin, near my ankle, which is sore; and dropping the weight down that leg is difficult as it seems quite tight :(.
A few years ago I went and had some lessons with Sue Neville-Parker, and I remember she had lots of wonderful ideas for practising riding when not on a horse (I think she even talked about having old saddles made into chairs; something I have always wanted to do!). I remember her having an exercise ball to train the seat and 'feel' whilst also limbering up - however at 5'10" I have great difficulty finding exercise balls big enough for me to sit on without my knees under my chin!
Anyone have any good horse rider exercises?
My props include 2 hula hoops (I cant hula hoop though - have you ever tried?! Its so hard!), yoga mat and weights.
Thanks!
