Reactiv uses sports-science-informed principles to build structured, sport-specific warm-ups — not random workouts. Every session is sequenced from a controlled, curated activity database the AI assembles to your context.
Generic AI workout apps invent exercises on the fly. Reactiv doesn't. Every drill comes from a curated database tagged for stimulus, joint demand, intensity and neuromuscular load. The AI's job is selection and sequencing — not invention.
The IOC-endorsed warm-up framework (Jeffreys, 2007). Sequenced to elevate core temperature, recruit stabilisers, mobilise joints through sport-specific ranges, and prime the neuromuscular system.
Heavy or ballistic conditioning contractions improve subsequent power output for 4–10 minutes (Blazevich & Babault, 2019). Reactiv times your loading window so you peak when it counts.
Short-duration, high-velocity drills increase motoneuron excitability and rate coding — sharpening reaction time and force production without inducing fatigue.
Plyometric and change-of-direction work conditions the stretch-shortening cycle, improving elastic energy return and decelerative control on first contact.
Dynamic mobility primes the joints through sport-specific ranges of motion. Ankle dorsiflexion for change of direction. Thoracic rotation for serves and rotational sports. Hip flexion and extension for sprint mechanics. Static stretching is deliberately avoided pre-match — it can transiently reduce force output.
Brief reactive cues — visual, auditory, decisional — recruit high-threshold motor units and prime the central nervous system without inducing fatigue. Designed to translate into faster first contact, not gym performance.
The final block rehearses patterns specific to your sport: cuts, decelerations, shadow strokes, jumps, sprints. The goal isn't conditioning — it's pattern priming so the first competitive rep feels like the tenth.
A real coaching voice walks you through every cue, breath and rest. Tempo, intent and intensity are spoken in real time so you can keep your eyes on the work, not your screen. Voice coaching can be turned off any time — and when it is, no voice credits are used.
Five inputs change every session: sport, time available, equipment, intensity goal, and how you feel right now. A 6-minute pre-match primer, a 22-minute full prep block, hotel-room with no equipment, post-injury easing — all assembled from the same controlled framework.
Reactiv is sports-science-informed preparation software — not medical advice and not a guarantee of performance improvement or injury prevention. If you have an injury, condition or doubt about a movement, consult a qualified clinician before training.
Recovery isn't lying still. It's an active sequence: bring the system down, restore tissue length, release the areas that took the most load, then regulate the nervous system into the parasympathetic state where actual recovery happens. D.R.R.R. is how Reactiv does it.
Low-intensity rhythmic movement and slow nasal breathing actively shifts the autonomic balance from sympathetic to parasympathetic, accelerating heart-rate recovery (Stanley et al., Sports Medicine, 2013).
Post-exercise dynamic and held stretching restores joint range and tissue length without compromising subsequent performance, when done after — not before — load (Behm et al., Applied Physiology Nutrition Metabolism, 2016).
Self-myofascial release (foam roller, lacrosse ball) reduces perceived muscle soreness and improves short-term ROM via neural and tissue mechanisms (Wiewelhove et al., Frontiers in Physiology, 2019).
Slow extended exhalations and HRV-style breathing protocols increase vagal tone and shift HRV markers toward recovery (Laborde et al., Neuroscience & Biobehavioral Reviews, 2017).
Reactiv applies these principles as software, not medical advice. Recovery responses vary by individual, training history and sleep — consult a qualified clinician for injury or pain.
