Riding is definitely a workout! I rode western for a few months when I was probably 12? I enjoyed it and you definitely feel the difference between english and western riding! While it wasn't for me, I still had fun trying something new! I wasn't sore after riding western the first few times, but boy there's something about english riding that makes me walk like a cowboy the next day (and western riders, please don't take that the wrong way, I'm talking a cowboy from back in like the early 1900's and how they walked in the old western movies and such!)
Two weeks ago I started picking lessons back up and my trainer really likes to do work with no stirrups. Me having not been that physically challenged on a horse before + having not done "no stirrups" work in forever = horrifically sore the next day! But I do have to say it really helps! I get up the next day and really feel it. My trainer told me like 10 minutes after doing it "Are you starting to feel sore?" of course I replied "yeah" in which her response was "Good, that means you're doing it right."
Of course I've done all of it before, but even now I still get really sore when I get home it's almost sad
then again, I haven't done work like that in so many years. Now that I'm working with a youngster who could be potentially mine that needs a good bit of work, it's going to be even more physically strenuous. But I tell myself: I need to be more physically challenged and it will definitely be rewarding in the long run!
As of right now, after riding today, I feel like I have giant bruises on my inner thighs -_- ouch! What comes next? - Wake up and proceed to the "walking like a cowboy" phase, lol.
