If you are wearing spurs, you can jab your horse unintentionally. If your horse is unfamiliar with you, or is nervous and excitable, ride it in a ring or enclosed area until he settles down. For safety, take along a companion when trail riding on such a horse. Spirited horses with extra energy may also be longed before ridden. Wear suitable clothing.
Protective headgear is advisable and essential when jumping.
Boots or hard riding shoes are an absolute must. Clothing should be designed for riding and fit snugly but not tightly. After you have ridden for a few minutes check the girth again. This may seem like needless repetition but it is necessary on most horses. Check without dismounting, take the reins in your right hand, and with your foot still in the stirrup, swing your left leg up and onto the horse's shoulder.
