If you want to build that core strength, fine tune your eq, and get your core and hand aids in sync, I HIGHLY recommend an Equicube (or similar weighted object). When I first made the switch from western to dressage, I was handed a brick to hold while riding and told not to drop it 😭. That brick got the gears turning in my head for what I needed to be doing and using. A few years later, the EquiCube was released! A few months ago I used it for a position tune up and to get that core working. Any rider of any discipline could use an exercise and tool like this! And of course, if you don’t have access to one or want to buy one, theres probably a similar shaped and weighted object lying around that you can hold
