Serpentines over Poles
A fun exercise which I recently did with my trainer is riding serpentines over poles! Place two poles in the middle of the arena and three poles on each side of the center poles. Then ride your serpentines over the poles! You can decide to ride over just the three poles on each side for a three loop serpentine or go over all the poles making it a 4 loop serpentine, depending on the size of your arena! This really helped me to get my lines right and is just a nice change to switch things up a bit!
