Let's do this. We're all big boys and girls here, so let's have a rational discussion about horses and riders. The subject of a riders weight has been taboo here for a while, too long...as it turned taboo when I left here a couple years ago.
When is a person too big to ride their horse?
Obviously there are many factors that play into this such as
a) body type of horse: a horses build tells us a lot about how much a horse can carry. Obviously a horse with a long weak back is not going to be able to carry as big of a rider as a horse with a shorter, strong back.
b ) horses overall condition: its easier for a horse to carry more weight if the horse is fit and using himself correctly as opposed to a horse that is out of shape and can't use himself properly.
2) Tack fit: proper tack fit allows proper weight distribution, ill fitting tack can put uneven pressure on a horses back, causing soreness and back pain.
a) skill: it's a known fact that an experienced, balanced rider does not put as much torque on a horses back as an inexperienced rider.
b ) size. *GASP* there. I said it. A riders weight has A LOT to do with riding. It's common sense that a horse is an animal and can only carry a certain amount of weight. It's just how it is. A heavy, unbalanced rider will put A LOT more strain on horse than a lighter unbalanced rider will. It's common sense.
There's *so* many different factors. When it all comes down to it, it takes common sense and the ability to read your horses response. If you're riding a horse and it's telling you you are too heavy, or too inexperienced (heavy hands, way too much leg, etc etc) you need to listen to that horse and change the way you ride or get off.
So, lets all be adults and discuss this. How heavy is too heavy?
