For Personal Trainers & Gym Owners
The Lean Greens affiliate programme pays 10% commission every time a client you refer places an order, not just once, but for as long as they're a customer. Some of our affiliates are still earning from referrals they made over a decade ago.

The maths, straight up
Your earnings estimate
Move the slider to your client count and see your estimated commission in real time.
Estimate based on: £55 average order value, 10% commission rate, 40% conversion rate from PT recommendation, monthly subscription reorder assumed. Actual earnings will vary. These are illustrative figures based on real affiliate performance data.
Why it works
Lean Greens has been trusted by 20,000+ UK customers for over a decade. Your clients aren't being sent to a new brand. They're being sent to one with a long track record.
Collagen Greens combines a full greens blend, hydrolysed bovine collagen peptides (Type I & III), and creatine monohydrate. All in one daily scoop. One product, one habit, one easy recommendation.
Affiliate-referred customers convert at a higher rate than cold site visitors. A recommendation from someone's PT carries trust that no ad can replicate, and we've seen that in the data consistently.
As an affiliate, you can offer your clients bundle deals that aren't available on the main website. Better value for them, higher order value for you.
The lifetime commission model only works because customers actually reorder. Lean Greens has a strong subscription retention rate, which means the income you build doesn't just spike and disappear.
Your affiliate toolkit
No guesswork. No complicated systems. We've built this so a PT can be live and earning within minutes.
I've been earning from the same clients for years. It just runs itself.

Is this for you?
The Lean Greens affiliate programme isn't built for content creators who've never used the products. It's built for fitness professionals who already have conversations with clients about nutrition, sleep, and recovery every single week.
You already talk to clients about nutrition. Now earn every time they act on your advice.
Recommend products your members will trust and build a supplementary revenue stream for your business.
Share your affiliate link in your newsletters, programmes, or group coaching spaces.
If you have a following, even a small and engaged one, your recommendation carries weight.

For the lifetime of the customer. If someone you refer in 2025 is still ordering in 2032, you're still earning commission on every order they place. We have affiliates who have been earning from the same customers for over 10 years.
Your affiliate link only tracks new customer referrals. If a client has ordered before, they won't be attributed to your account, so it's worth sharing your link with new clients as you onboard them.
Yes. As an affiliate you have access to exclusive bundle offers that aren't available on the main Lean Greens website. These give your clients better value and often increase the order value, which means higher commission for you.
Commission is paid out at the beginning of each month for the previous month's earnings. The minimum payout threshold is £50. Payments are made via GoAffPro. You set your preferred payment method when you sign up.
You're not dealing with a ticket system. Get in touch directly and you'll hear back from a person. We want our affiliates to succeed. It's in our interest as much as yours.
No, though most of our best affiliates are, because they can speak from personal experience. If you haven't tried the products, we'd suggest starting with Collagen Greens. It's the easiest to recommend and the most popular with PT clients.
