I experienced an interesting sensation on Friday and today while working horses (didn't make it out there yesterday). I have four that I work, and usually by the fourth one my stamina is flagging and I have a tendency to want to wimp out. However, both Friday and today....I didn't. I, like, was fine. In fact, I felt like I could do another. I think I'm actually FINALLY getting fitter!
Now that I have two horses going under saddle but don't want to ride either one too much, I'm going to alternate and ride each of them twice per week. That gives me four days of riding, which is better exercise than standing there and longeing...well, different exercise, at least! Rode Max on Friday and Molly today.
