I bought a 15 yo OTTB last month and he hasn't been worked since last summer. I know that TB are more "ribby" than other breeds but I felt he was underweight and he's also lacking hind muscle that he used to have. (I previously leased him so I know what he used to look like).
I've been doing small grids/gymnastics excersizes, he free lunges but is scared to death of lunge whips. I work him every day for about 1-2 hrs. We've jumped some, worked flatwork ALOT, tried some dressage excersizes, and i've seen just a tiny bit of change in his muscle tone.
How long will it be until I will see the difference? What can I do to help improve and strengthen him back up?
