Active Isolated Stretching is a precise stretching method that uses short, repeated stretches and active muscle engagement to improve flexibility and mobility more safely than prolonged static holds. At Body Heal, AIS is used as a clinical tool to restore movement, support athletic performance, and address restrictions caused by training, injury, or daily life.
Active Isolated Stretching is a precise, science-based stretching method developed by kinesiologist Aaron Mattes that works with the body’s neurological design rather than against it. Unlike traditional static stretching — where a position is held for 30 seconds or longer — AIS uses short, two-second stretches repeated in sequences, with the client actively contracting the muscle opposing the one being stretched. This active engagement triggers a neurological response called reciprocal inhibition, causing the target muscle to release more completely and more safely than passive holding allows. The result is a stretching method that produces meaningful gains in flexibility and mobility without the tissue resistance, discomfort, and potential for micro-damage that prolonged static stretching can create. At Body Heal, AIS is used as a precise clinical tool for restoring mobility, supporting athletic performance, and addressing the movement restrictions that accumulate through training, injury, and daily life.
The nervous system governs how far a muscle will stretch — when it senses a stretch going too deep or held too long, it triggers a protective contraction that limits range of motion. AIS bypasses that protective response by keeping each stretch within the two-second window before the reflex activates, and by using reciprocal inhibition to encourage the target muscle to release. The result is a neurologically cooperative stretch that achieves greater depth with less resistance and less discomfort than static methods.
Because AIS works in repeated cycles rather than a single sustained hold, each repetition builds on the last — progressively increasing range of motion within a single session as the nervous system adapts to the new movement pattern. Over multiple sessions, those gains accumulate into lasting improvements in flexibility and movement quality that transfer directly into athletic performance, daily movement, and pain-free function.
Traditional static stretching held for extended periods can temporarily restrict blood flow to the tissue being stretched. AIS avoids this by keeping stretches brief and rhythmic — each two-second cycle creates a pumping effect through the tissue that increases circulation, supports lymphatic flow, and delivers fresh oxygen and nutrients to the muscles being worked. This makes AIS particularly effective as part of a warm-up, a recovery session, or a rehabilitation protocol.
AIS is a whole-body methodology — it addresses not just isolated tight muscles but the movement patterns and kinetic chain relationships that connect them. A restriction in the hip affects the low back. A tight thoracic spine affects the shoulder. AIS works through these relationships systematically, restoring mobility in a way that improves how the whole body moves rather than just increasing the range of a single joint.
Active Isolated Stretching is appropriate for a wide range of clients — from competitive athletes seeking performance-level mobility gains to individuals managing age-related stiffness, postural restrictions, and movement limitations from sedentary work or injury. It is particularly valuable for runners, cyclists, and endurance athletes managing hip flexor, hamstring, and thoracic restrictions that affect stride efficiency and performance; strength athletes whose training patterns create predictable tightness in specific movement planes; clients in rehabilitation whose range of motion has not fully returned following injury or surgery; and older active adults whose tissue has lost the elasticity and responsiveness that AIS is specifically designed to restore. At Body Heal, AIS is integrated within Sports Massage and Bodywork sessions and can also be the primary focus of a session when progressive mobility restoration is the primary goal.
Pre-event sports massage is a focused, stimulating session designed to prepare the body for athletic performance — whether that is a race, a competition, a game, or an intense training session. Unlike a recovery or maintenance session, pre-event work is not about going deep or producing significant tissue change. It is about waking the body up — increasing circulation to the muscles that are about to be demanded, reducing tension that could limit performance or contribute to injury, and priming the nervous system for the work ahead. At Body Heal, pre-event massage is precise and purposeful — targeted to the muscle groups specific to your sport and timed to work with your warm-up and competition schedule, not against it.
Maintenance sports massage is regular, scheduled bodywork built into the training cycle — not as a response to pain or injury, but as a proactive investment in how the body performs, recovers, and holds up over time. While pre-event and post-event massage address specific performance windows, maintenance massage works in the space between — managing the cumulative load that builds across weeks and months of training, identifying and addressing problems before they become injuries, and keeping the tissue in the kind of condition that allows consistent, high-quality training. At Body Heal, maintenance massage is how serious athletes and active individuals stay ahead of the breakdown curve rather than constantly reacting to it.
Post-event sports massage is recovery-focused bodywork delivered in the hours and days following athletic competition or an intense training session. When the body has been pushed hard — a race, a tournament, a heavy training block — the tissue accumulates metabolic waste, micro-damage, and inflammatory byproducts that need to be cleared for recovery to proceed efficiently. Left unaddressed, that accumulation contributes to prolonged soreness, stiffness, reduced range of motion, and a slower return to full capacity. Post-event massage supports the body’s natural recovery process by flushing waste, reducing inflammation, restoring tissue mobility, and beginning the process of identifying and addressing any acute tension patterns before they become chronic. At Body Heal, post-event work is calibrated precisely to where your body is in the recovery timeline — the approach on race day is different from the approach 48 hours later.
Restorative sports massage is a deeper, more therapeutically focused recovery session designed for the athlete or active individual whose body needs more than a standard flush — one whose tissue has accumulated significant restriction, chronic tension, or overuse patterns that routine recovery work is no longer fully addressing. Where post-event and recovery massage work broadly to support the body’s return to baseline, restorative massage goes further — using clinical soft tissue techniques to address the specific restrictions, trigger points, and compensation patterns that have built up over a training cycle and are beginning to affect performance, movement quality, or comfort. This is the session that resets not just how the body feels but how it moves — clearing the deeper layers of accumulated strain so the athlete can continue training from a genuinely restored foundation rather than a managed one.
Performance massage is a strategically designed session built around one specific goal — optimizing how your body performs. While recovery massage focuses on what the body needs after effort and maintenance massage manages cumulative load between sessions, performance massage sits at the intersection of both — using a targeted combination of techniques to ensure that the tissue, the nervous system, and the movement patterns supporting your athletic output are as prepared, mobile, and responsive as possible. This is not general bodywork applied to an athletic body. It is a purposeful, assessment-informed session built around your sport, your training demands, your performance timeline, and the specific physical factors that either support or limit your output. At Body Heal, performance massage is the session serious athletes return to consistently because the results are measurable and the impact on training quality is direct.
AIS uses short, repeated stretches where you actively move into a position and we assist at the end range. It is designed to improve flexibility without long holds. It often feels smooth, specific, and athletic.
It is great for athletes and active clients who want mobility gains that transfer into movement. It is also helpful when long holds feel irritating or when your body responds better to repetition. We use it when assessment shows a clear mobility limiter.
Not usually. AIS works best when combined with soft tissue techniques that reduce restriction. We often blend AIS with sports massage so your range of motion improves and holds.
Most people feel more mobile rather than sore. Mild tenderness is possible if the tissue was very restricted. We keep it within a productive range and adjust based on your response.
Active Isolated Stretching uses short, repeated movements instead of long static holds, helping the body improve flexibility and mobility without forcing the stretch. Because the client actively participates and the therapist assists at the end range, AIS can feel more controlled, specific, and useful for movement-based goals.
