Hello Megan, it is hard to explain so here's an example : https://keyassets.timeincuk.net/inspirewp/live/wp-content/uploads/sites/14/2015/07/V-pole-e1438165706787.jpg
Just posted a v shape jumping with my horse. Have a look there
I had the same trouble with my horse. The best exercise to me, is the v bars.
You can do a full cours with V bars on every jumps on just a shcooling exercise.
Good luck :)
