Warming up is the part of a training session most likely to be shortened when time is short, skipped when a horse seems fresh, or treated as a formality rather than a functional preparation phase. In most cases this does not produce an immediate problem. Over time, and in the right circumstances, it does.
Warming up is not simply about loosening muscles. It prepares the mechanical and biological environment of tendons and ligaments for the loads that follow. A well-executed warm-up period reduces the vulnerability of soft tissue at the start of work. Warming up inadequately leaves structures exposed to peak loading before they are physiologically ready to manage it.
What Happens to Soft Tissue During Warming Up
At rest, tendons and ligaments are at a lower temperature, lower fluid viscosity, and reduced mechanical responsiveness compared to their state during active work. The synovial fluid within tendon sheaths and joints is more viscous when cold. The viscoelastic properties of tendon tissue, its ability to deform under load and return to its original shape, are less optimal at rest temperature than at working temperature.
Gradual warming up changes this. As the horse moves at low intensity, blood flow to the distal limb increases, tissue temperature rises, synovial fluid viscosity decreases, and the mechanical responsiveness of tendon and ligament tissue improves. The structures become more capable of managing the repetitive loading cycles that training and competition demand.
Asking a horse to perform high-intensity efforts before this preparation has occurred means the tendons and ligaments are absorbing peak loads before they have reached their optimal functional state. The mechanical vulnerability of cold soft tissue is real and measurable. It is one of the reasons injuries in performance horses occur disproportionately early in sessions or in horses that have not been adequately warmed up before demanding work.
The Temperature Effect on Tendon Mechanics
This is worth understanding specifically. Tendon tissue is viscoelastic, meaning it deforms under load and recovers. The efficiency of that deformation and recovery cycle depends partly on tissue temperature. Cold tendon tissue is stiffer and less able to distribute load evenly across its fiber structure. Peak stress concentrates at specific points within the tissue rather than being distributed across a broader cross-section.
As tissue temperature rises through appropriate warming up, stiffness decreases, load distribution improves, and the tendon handles each stride's loading cycle more efficiently. The same load that creates localized stress concentration in a cold tendon is distributed more evenly through a warm one.
This mechanical difference is the physiological basis for the recommendation to warm up properly that experienced practitioners and trainers have long understood intuitively: cold horses going directly into demanding work are at meaningfully higher soft tissue risk than horses that have been properly prepared.
What Inadequate Warming Up Looks Like
Inadequate warming up is not always obviously insufficient. A horse that walks for five minutes and trots for two before being asked for collection, jumping, or speed work has technically started warming up. Whether that is enough depends on the horse, the ambient temperature, and what the work that follows demands.
In cold weather, tissue temperature rises more slowly and the time needed to warm up adequately is longer. Warming up for the same duration on a cold winter morning may be insufficient compared to a summer afternoon.
Horses coming out of stall confinement have been stationary for hours. Their synovial fluid is more viscous, their muscles are less prepared for load, and their neuromuscular patterns for the specific demands of their discipline have not been activated. These horses need more preparation than a horse that has had turnout or light hand walking before being ridden.
Horses returning from time off, whether for injury, illness, or seasonal reasons, have reduced conditioning and soft tissue adaptive capacity. They require more time warming up than a fit horse in regular work, not lower.
Practical Guidelines for Warming Up
The appropriate amount of warming up varies by discipline, horse, ambient temperature, and the demands of the session that follows. General principles that apply across most performance contexts are consistent.
Begin at walk. Walking on a loose rein allows the horse to move freely, builds initial circulation to the limb, and begins the thermal preparation of soft tissue without placing any significant load on it. A minimum of ten minutes at walk is a reasonable starting point for most horses before trot work begins.
Progress gradually. The transition from walk to trot, and from trot to the demands of the specific session, should be incremental. Short periods of trot at low intensity before sustained trot work, and sustained trot before canter or discipline-specific demands, allow soft tissue to adapt progressively to increasing load rather than moving abruptly from low to high intensity.
Allow more time warming up before higher-demand sessions. A horse about to jump a full course, perform an advanced dressage test, or compete in multiple chukkers needs more preparation than one doing a light flatwork school. The time spent warming up should be proportional to what follows.
In cold weather, lengthen the warming up period. Cold ambient temperature slows the tissue temperature rise that warming up produces. Adding five to ten minutes of additional walk and low-intensity trot in cold conditions compensates for the reduced rate of thermal preparation.
Pay attention to how the horse moves while warming up. A horse that is consistently stiff on one rein, takes longer to loosen on one side, or shows movement asymmetry while warming up that does not resolve is providing useful information about where soft tissue tension or discomfort may be developing.
The Cool-Down Is Part of the Same Process
A proper warming up period has a counterpart at the end of the session. Just as abrupt transition from rest to peak loading increases soft tissue vulnerability, abrupt cessation of intense work without a cool-down period leaves the distal limb at elevated temperature and with metabolic byproducts from the session that need to be cleared.
Finishing sessions with decreasing intensity, ending with walk, and following that with active cold therapy for the lower limbs completes the thermal management cycle that warming up begins. Warming up and cooling down are bookends of the same soft tissue management practice.
Supporting Soft Tissue Through Every Session
Warming up and cooling down address the mechanical preparation of soft tissue for each session. Consistent nutritional support addresses the biological environment in which tendons and ligaments function and repair between sessions.
Tendonall is formulated to support tendon and ligament biology and is used as a sustained management strategy throughout the training and competition season, supporting the continuous repair and remodeling processes that keep performance horses sound through demanding work.
Warming up is not a formality. It is a functional preparation phase that changes the mechanical state of tendons and ligaments before peak loads are applied. Getting it right consistently, across every session and in every season, is one of the most accessible and underutilized soft tissue management practices available to performance horse owners and trainers.
