What can happen when exerting effort on an arena surface that is too soft?

Exerting effort on an arena surface that is too soft can lead to muscle strain and fatigue for several important reasons. When the footing is overly soft, it does not provide adequate support and stability for the horse's movements. As the horse pushes off the ground, the soft surface absorbs too much energy, forcing the horse to exert more effort than usual to maintain speed and balance. This extra effort can strain the muscles, tendons, and ligaments, increasing the risk of injury.

Additionally, consistent exposure to such conditions can lead to chronic fatigue as the horse's muscles work harder to compensate for the lack of support from the surface. This can ultimately impair performance, as the horse may be unable to work effectively or comfortably under these conditions. Maintaining the proper arena surface is crucial for both the safety and performance of the horse.
