For better leg position, there are several things to do. First of all, practice a lot of two-point at the walk and the trot. It forces your leg into the proper position while making your thighs stronger. Lunge lessons (where someone lunges a well behaved lesson horse while you ride without reins) are also very very helpful, as you have to rely on the strength of your legs to keep you on the horse. I'm not talking death grip, but firm solid contact with the saddle. Remembering that your shoulders should be right over your hips, heels down (but not so far down your feet are numb when you dismount), and that your  thighs and knees should be the only part of your leg gripping the saddle. Don't get to thinking that your calf cannot touch the horse's side!  As you get more and more comfortable with your position, try to mix in harder elements such as dropping your stirrups at the trot, riding with a dollar bill between your knee and the saddle, or for the very brave, posting the trot bareback. Ask your trainer, friend, or someone who knows a lot about equitation to watch you ride and give you pointers. - submitted by Laura
