Depends on the riding.

When I was taking lessons, I would ride for 45 minutes and get off with
rubber tired legs. The next day, my abs and legs would be sore. Trail
riding did not produce this effect unless we did a lot of trotting.

But it's not just a free ride. If you are riding at least somewhat
well, you are maintaing proper posture, using your calf muscles to
squeeze and direct the horse. Your arms are up and away from your body.
Not the same as lifting weights, but just stand for half an hour and
hold your arms up. They will get tired if you aren't used to it. And
your abs should be working with every stride.

It is actually pretty good exercise, and I lost weight steadily back
when I was riding twice a week.
