This probably belongs in the returning to riding thread but I don’t know if that’s still going. We bought my highland cross home at the end of January. She’s shared between myself (who used to be a competent rider 20 years ago) and my 14 year old son. She was very unfit, very unresponsive and nappy when she arrived but hadn’t done any arena work and was ridden by a novice who just used to take her for a walk. She’s come on a lot but still has a way to go. We’ve been doing lots and lots of hacking. I was worried that this mornings lesson would see her not being very responsive but in fact it was me who was a bit rubbish. My lower legs started really hurting part way into the lesson and they are ever so achey now. What things can I do to get myself in better working condition!?
