Gentle Hamstring Recovery

What you can ask for
Any situation. Any goal.
The AI handles everything from injury recovery to sport-specific prep. If you can describe it, it can build it.
Recovering from injury
Describe the affected area and where you are in recovery — 'post-ankle sprain, gentle mobility work only' or 'shoulder impingement, avoiding overhead' — and the AI builds a session that works around your limitation, not through it.
“Recovering from a mild hamstring strain, nothing too aggressive”
Post-workout recovery
Tell it what you trained and how hard. The AI selects the right passive and active stretches to address the muscles you worked, reduce next-day soreness, and restore full range of motion before your next session.
“Heavy leg day — squats and deadlifts, glutes and hamstrings are done”
Pre-workout activation
Describe your sport or training style and the AI builds a targeted warm-up — priming the joints and movement patterns you'll actually use, not a generic set of hip circles.
“Pre-run warm-up, half marathon training, tight calves lately”
Desk worker daily reset
Hours at a desk shorten hip flexors, restrict thoracic rotation, and lock up shoulders. Describe your day and the AI targets exactly what prolonged sitting does to your body.
“Sitting at a desk for 8 hours, hips and lower back feel compressed”
Sport-specific preparation
Whether you're a swimmer, rugby player, BJJ competitor, or golfer — describe your sport and the AI draws from the full exercise library to build the warm-up or recovery session your specific movement demands.
“Swimmer — shoulders and thoracic spine feel locked up after training”
Travel & limited space
On the road, in a hotel room, or without any equipment. Tell the AI your constraints and it selects floor-based, bodyweight-only exercises that work in a tight space with nothing but a mat.
“Hotel room, no equipment, just flew 10 hours and feel stiff everywhere”

GeneralUnder the hood
How it works
Built to be fast, grounded, and safe. The AI picks exercises — MotionLab builds the session.
You describe your situation
Type anything in plain language — a body part, a feeling, a sport, a time constraint. No dropdown menus, no category selection. Just tell it what's going on.
Gemini reads your intent
Your prompt is sent to Gemini 2.5 Flash alongside a compact catalogue of every exercise in MotionLab's library. The AI identifies your target areas, infers whether you need recovery, activation, or maintenance, and selects the right exercises.
Your session is built instantly
The model returns an ordered list of exercise IDs. MotionLab looks up each one, fills the session to your chosen duration, and hands you a complete guided session — ready to start in seconds.
Why Gemini 2.5 Flash?
Gemini 2.5 Flash with thinking disabled is the right tool for this task. It's fast, token-efficient, and handles natural language to structured output mapping with high accuracy. Internal chain-of-thought reasoning is disabled — for a classification task this focused, it adds latency with no quality benefit. The result is responses typically under 2 seconds.
Built with safety in mind
The AI selects from MotionLab's curated exercise library — it does not invent exercises or generate its own instructions. Every stretch in the library was written by humans with clear safety cues, breathing guidance, and when-to-stop notes.
For injury recovery, the AI prioritizes gentle, non-loading movements and avoids exercises that require force at end range. We still recommend consulting a physiotherapist for serious or acute injuries before starting any mobility programme.
Your data stays yours
Your prompt is sent to Google's Gemini API to generate the session. It is not stored by MotionLab beyond the session generation request, and is not used to train AI models.
Your mobility scores, session history, and personal data remain in your private Firebase account and are never shared with any AI provider.
