Sitting Trot

First of all, do not grip with your knees and sit very deep into the saddle. You need to try to absorb the movement by relaxing your weight down and allowing your hips to move forward with motion.

          To sit to the trot comfortably, you first need to be sure that your tack is correctly fitted and that your horse is supple and balanced enough to work well from behind. Common causes of the rider bumping about in the saddle include bad posture, collapsing through the pelvis, gripping with the knees, legs slipped forward or back, excessive head or set movement, or stiffness due to anxiety. Many of these problems can be related back to poor core stability.

Try these exercises on the lunge to improve your core stability and balance. All exercises are without reins and stirrups:
1. Sit square At halt, take your legs away from the horse’s sides, lifting from your hips. Keep a straight line between shoulders, hips and heels, and maintain your upper body position. Hold briefly and relax. Does you body then tip forward or back? Tipping forwards means you should be sitting further back on your seat bones, and vice versa.

2. Torso turning Make sure your upper body moves independently of your lower body. First at walk, with your seat and legs still, twist your torso to the inside of the circle and then to the outside. Keep your arms and hands as if they are holding the reins. Then try it at trot.

3. Arm circles
Starting in walk, circle your one arm forwards while making sure your legs and seat remain in position. Then circle it backwards, before swapping arms. Then try both arms at once, starting by going in the same direction and then in opposite directions. Recheck that you are sitting squarely on your seat bones
