yep - get on a stair. hang your heels off the edge of the stair, then "get in two point" do some modified squats like that, slowly up and down, hold onto a railing till you can balance without it.

thighmaster? i have a whole book of those exercises,,,,someone has borrowed it though

you really need to go back to flat work
do little cross-rails and poles, but don't jump anything bigger than 18".
talk to your trainer about getting another day, and just work on walking and trotting until you feel secure enough to move on. there are many people out at your stables that will be willing to help you and coach you through it, talk to your instructor about working on it, because it is important to make sure you have a good foundation before you move on to jumping bigger fences.

a great exercise is working all gaits in the vertical far positon (standing). it helps your balance and will teach you to sink into your heels, just make sure you dont catch the pony in the mouth when you do this. this well help you learn how to distribute pressure evenly along your leg, and other people have posted the same thing, your pivoting off your knee. alot of that actualy comes from riding in a saddle with knee blocks, you learn to ride the block and not the pony. i ride in a saddle that has no blocks, no padding, and barley any dip in the seat.
