One place, not three apps
Members juggle a tracker they pay for, a gym app they ignore and a coach on WhatsApp. Fold it into one: an award-winning consumer app, included with their membership, wearing your gym's support around it.
LeanShield™ for Gyms
Turn the GLP-1 wave into your gym's retention engine.
Your members already pay for tracking apps like MyFitnessPal — separately from you. Bring it all into one place: give them ParrotPal or Turtle Method as part of membership, let LeanShield™ watch the muscle they joined your gym to build, and give your team a dashboard that spots who needs support before they disappear. A member benefit at the front. Churn insurance at the back.

🏴 Founding gym №1: HYVE
Why now
GLP-1s changed your gym floor.
GLP-1s changed your gym floor.
Muscle is how you win it.
1.6 million GB adults used weight-loss drugs in a year — and millions more are interested. They're losing weight fast, worrying about muscle, and asking for nutrition support. Premium clubs like Equinox have already built GLP-1 protocols. You don't need to become a clinic — you need a measurement layer.
Muscle is your home turf
Up to 40% of the weight lost on GLP-1s can be lean mass — muscle included. Protecting it takes protein and strength training. That's not a pharmacy's offer. It's yours.
Churn insurance, built in
The member who stops logging this week is the member who cancels next quarter. LeanShield Coach surfaces the moment to reach out with care — a check-in, a free PT session, a reason to stay.
Founding gym №1
HYVE is the first LeanShield gym.
HYVE — one of Wales' largest independent gyms, across Llanelli, Burry Port and Cardiff — is the first to bring LeanShield to its members. Every HYVE member gets our award-winning consumer apps as part of their membership: voice-first food logging, their own muscle-safety score with workouts prescribed to raise it, weekly check-ins, and community support online and on the gym floor. And HYVE's team gets the layer that makes it stick — live proof their members are protecting the muscle they train for.
How it works
Three layers. One system.
01
Members choose their app
ParrotPal for everyone; Turtle Method for women's health — on iPhone and Android, included with membership. Voice-first logging, so they actually use it. Their data stays private by default.
02LeanShield scores the thing that matters
Every member sees their own 1–100 muscle-safety score — whether their fat loss is protecting the strength and shape they're training for. The nudges point at protein, strength sessions and safe pace — and LeanShield prescribes score-boosting workouts automatically. Your PTs add the form coaching on the floor.
03
Your team sees the right view
You see anonymous, aggregate gym trends. Your PTs see individual members only when that member opts in to coaching — then they get the full picture and the moment to act on it.

"Who needs me today?"
Daily alerts rank opted-in members by the support they need — with the reason attached, and one tap to a voice note. Praise included: wins matter as much as risks.

The badge
Become a LeanShield™ Certified Gym.
Certification means your gym meets the muscle-safety standard: your team briefed on GLP-1-era coaching, strength-first support for members losing weight, and the privacy model running as designed. Then you get the badge — for the door, the website and every membership conversation.
- Staff briefed — muscle-safety standards, scope, and when to refer to a clinician
- Members protected — strength-first programming for anyone losing weight fast
- Privacy live — opt-in coaching, aggregate-only owner view, one-tap revocation
- The badge — LeanShield Certified Gym, the mark that says you watch the muscle
Care, not surveillance
Members trust it — or none of this works.
The app belongs to the member. Coaching is an explicit, named, revocable choice. The owner view is anonymous and aggregate, with minimum cohort sizes. No member list, no food-log peeking, no "the owner is watching your weight" — ever. The full picture is on our Trust & security page.

A 12-week founding pilot: member apps live in week one, your branded launch comms, the coach dashboard for your PTs, and a board-ready aggregate report at the end. Founding gyms shape the product and earn certification first.
Your members are already on the jabs. The only question is which gym helps them keep the muscle.
