A false martingale — also known as a breastplate martingale or anti-grazing strap — is a simple piece of tack designed to prevent a horse from lowering its head to graze while being ridden or led. Unlike a running or standing martingale, which acts on rein pressure or noseband to limit head height, a false martingale typically consists of a strap running from the girth, between the front legs, and connecting to the noseband or neckstrap — without any direct influence on the reins or bit.
What a False Martingale Does
The primary purpose of a false martingale is safety: preventing a horse from snatching its head down to graze suddenly while a rider is mounted. This is a genuine hazard, particularly with ponies ridden by children who may not have the strength or experience to prevent it. A horse that drops its head sharply to grab grass can unbalance an inexperienced rider and, in the worst case, pull them over its head.
In some contexts, a false martingale also plays a stabilising role similar to a breastplate — helping to prevent the saddle from sliding back on narrow-shouldered or lean horses, as the strap between the legs provides a forward anchor.
False Martingale vs Running Martingale
The distinction matters in practical terms. A running martingale has rings through which the reins pass, creating an indirect lever action when the horse raises its head above a certain point. It actively influences rein line and is a training and control tool. A false martingale has no influence on the reins whatsoever — it acts only on the noseband or neckstrap and is purely a physical limit on downward head movement. For this reason, a false martingale does not require the riding skill that a running martingale demands to use safely.
Fitting and Use
A false martingale should be adjusted so there is no tension when the horse carries its head in a normal working position. The strap between the legs should not hang loose enough to become entangled with the legs, but it must not be so tight that it restricts normal neck movement. Check that the connection point at the noseband or neckstrap is secure and that the strap between the legs sits centrally.
Most false martingales are used on ponies in general riding and leisure contexts rather than in competitive work, where more sophisticated equipment is available. They are commonly seen at riding schools, on leading reins, and for younger riders building confidence with forward-going ponies.
Competition Rules
Rules on martingale use vary by discipline and level. Always check the relevant competition rules before using any martingale type. British Horse Society guidance and British Riding Clubs rules are good starting references. For related equipment, see Standing Martingale and Running Martingale.
Frequently Asked Questions
Is a false martingale the same as a standing martingale?
No. A standing martingale connects from the girth to the noseband and physically limits how high the horse can raise its head above a set point. A false martingale connects from the girth, runs between the forelegs, and limits how far down the horse can drop its head. They address opposite extremes of head movement and work by entirely different mechanisms.
Do I need a false martingale if my horse grazes while ridden?
A false martingale is a physical solution to what is fundamentally a training issue. A horse that consistently attempts to graze while being ridden should be trained not to — particularly through consistent, clear boundaries from the rider and reinforcement of forward movement. A false martingale addresses the immediate safety concern but does not resolve the underlying behaviour. For persistent grazers, it is a sensible safety measure while training is ongoing.
Can a false martingale interfere with the horse’s movement?
If correctly fitted, no. It should hang with a slight loop between the legs and only come into tension when the horse drops its head significantly below normal carriage. If it is creating any contact during normal work, it is too short and should be let out. A false martingale that is constantly taut will interfere with freedom of the shoulder and should be readjusted immediately.
