I looooooove a good grid and given the times we are in, I try to do my grids an a separate day to my pole work so that I can keep Beag entertained but it goes without saying that grids and poles on the same day is totally fine.
My latest grid was inspired by @nobuckingwayblog, I set the grid up the evening after seeing the girls make it look easy on Instagram and I really enjoyed it. I find a grid really helpful for my position, it teaches me to sit up and keep my core engaged, it is more important to have the horse engaged and gathered rather than giving him his head over every fence, they don't need their head over small fences in a grid. They need you to keep your sh*t together and stay upright, a massive issue for me. *eyeroll*
Obviously it is incredibly good for our horses for many reasons but getting strides right is imperative, I have fallen (pun life) victim to far too many wrong strided bounces/grids and the results can be detrimental not only for you but for your horse.
I love seeing them online but it is important to make sure you have your strides right for your horse. Another account that is very informative for this is @centrelineequinetherapy, they popped up 'Pole Work Distances' on their grid earlier this week and I found it very informative.
