I agree that cavaletti and long-lining are great! Long-lining is fantastic for the youngins learning cues but it's also good for horse and rider to build muscle. Now, just find some hills where you can long-line and you'll be set. My filly's been long-lining since she was about 8 months. Great tool for manners, let me tell ya!

Oh... and be careful if you try to long-line over cavaletti. I tripped over one and I think my horse laughed at me...
