Riding is such good excerise.
Maybe not the actual riding but the running to get the pony (I seem yo be cursed with hilly fields) and lifting haynets and water buckets.
My friend wanted to go climbing all the hay bales I was like mm yeh because when we fall down in the middle and the whole stack collapses on us i'm totally gonna get a signal on my phone to call for help, plus i'm sure the horses don't want hay that's all muddy and trampled on.
