I got a hyper greenie, so I ride him every day. Though I don't ride him hard every day. It depends on the day (I don't have a riding ring, just the road and part of the front yard I have a jump set up on.) And how much energy my horse has. If he's tired I take it easy and don't spend much more than 15-20 minutes most. Just enough for a little walk, little trot and maybe a bit of a canter. But for the every other normal day it's even walk, trot, canter and finish with a bit of a jump/poles (Whatever we're working on that day, or a bit of both).
