Warm up is always the same. Walk 10 minutes, bending and serpentines during that time. Trot on loose rein, 5 to 10 minutes each direction, repeat with canter for slightly less time.
Two days a week are dressage day. Everything we do after warmup is done with the goal of achieving some degree on collection. Usually we do a zillion transitions until he shortens up his frame enough to be balancing himself. Lots of circles and leg yeilding. He's starting to understand shoulder in and haunches in.
Two other days are hunt seat/jumping days. Lots of poles, cavaletti and cross rails. Looser rein than "dressage" days, but still with contact. Much more half seat work on my part and more frequent changes of direction for him.
Two days are trails. Varied terrain. Really uses his muscles and gets the cobwebs out.
7th day off. Very hard for both of us. He loves to work.
He definitely doesn't show any signs of lameness. When I first got him, as a typical OTTB, he heavily favored his left lead. His right was this weak, overbent mess. I spend the past year building up strength on his left hind and right shoulder using the above mentioned lateral work and now his leads are so similar that I have trouble picking out if he's on the wrong one. His trot is much better that way too.
There seem to be two schools of thought about working the weak side. One is to do twice as much, or at least more work to the bad side than on the good side. The other is to start with the bad side and then don't anymore on the good side that you could do on the bad side. For example, if he can only canter 3 circles his bad way, don't do more than 3 the good way. I know the second option did wonders for evening him out on both reins. Maybe I should now switch to the first option for adding additional muscle to one side.
