Hopefully their riding has improved as this is an old video. The instructor should be held responsible for this. These riders have NO business jumping this high. The blue shirt was the most cringeworthy, as she should NOT have been jumping the Three combo that high, when having that many issues. Lower the fences, HIT the distances, CORRECTLY and SAFELY, and THEN raise the fences. SLOWLY. Perhaps you won’t have to beat your horse to make her go forward if you let her take a break once in a while. The way she was being ridden, she needs longer breaks then cantering halfway around the arena. This break, even if a short one, allows you as a rider to regroup as well!
