NForge vs Trainerize
LOOKING FOR A TRAINERIZE
ALTERNATIVE?
ABC Trainerize offers a free plan for 1 client, but paid plans scale to ~$275/month and the essentials stack on top: nutrition AI at $20-45/mo, video at $10/mo, payments at $10/mo. NForge gives you everything in one app — workouts, safety-reviewed AI, live classes, marketplace, payments — completely free with unlimited clients.

The gap
WHAT YOU GET ON NFORGE THAT TRAINERIZE DOESN'T OFFER
No monthly fee, no add-on stack
A feature-matched Trainerize setup means a tier subscription plus $10/mo payments plus $20-45/mo nutrition plus $10/mo video — and Stripe fees still apply on top. NForge ships every feature for £0/month; the only cost is 7.9% when a client actually pays you.
AI nutrition included, not paywalled
Trainerize's AI meal planning lives inside the $20-45/mo Advanced Nutrition add-on. Forge AI writes the workout AND the nutrition — daily targets with meals portioned to meet them — for every coach, free.
AI with a safety-review pipeline
Trainerize ships its AI as an editable draft that "needs a coach's eye" — nothing checks it. Every Forge AI plan is screened for allergies, injuries and conditions by code, re-checked by an independent AI review, and flagged plans arrive with specific notes before you approve them.
Clients never install anything
Trainerize clients live in the Trainerize app. NForge clients get programmes as professional PDFs and join classes from a browser link — zero downloads, zero onboarding friction.
To be fair: Trainerize is the most feature-complete incumbent among PT platforms — it genuinely offers group video calling (up to 49, via the $10/mo add-on), in-person booking with session packs, and a public Trainerize.me storefront. The real differences are the stacked bill and AI that ships unchecked.
Why trainers switch
TRAINERIZE VS NFORGE — THE REAL DIFFERENCES
Add-on costs push plans far past the sticker price
The problem
Trainerize's base plans look affordable, but essential features are separate add-ons: Advanced Nutrition with AI meal planning costs $20-45/month depending on tier, video coaching adds $10/month, Stripe payments add $10/month, and a branded app is $169 upfront. A fully-featured mid-tier setup runs $63-130+/month before Stripe's processing fees — and prices rose again in March 2026.
NForge's approach
NForge includes everything in one app: workout builder, nutrition planner, Forge AI, live video classes, marketplace storefront, automated invoicing, and client management. No add-ons, no tiers. The only cost is 7.9% when you get paid.
AI meal planning sits behind the nutrition add-on
The problem
Trainerize now has an AI Workout Builder (in beta, included from the $9/mo Grow plan) — but its Smart Meal Planner AI is locked inside the Advanced Nutrition add-on at $20-45/month. And in both cases the AI hands you an unverified draft: no allergen screening guarantee, no independent review, no flagged notes.
NForge's approach
Forge AI writes the complete programme — workout and nutrition together — screened for allergies at ingredient level, checked against injuries and conditions, re-reviewed by an independent AI pass, and delivered to you with plain-English notes. Included free, with fair-use limits instead of a paywall.
Client caps force expensive tier jumps
The problem
Trainerize gives you 1 client for free. Want 2? That's $9/month. Growth means climbing the Pro ladder toward ~$275/month at 200 clients, or $248/month per location on Studio Plus. The more clients you add, the more your fixed costs increase through mandatory tier upgrades.
NForge's approach
NForge has no client limits. Whether you have 1 client or 500, the platform is free. Your costs scale with your income through the 7.9% transaction fee. Earn nothing, pay nothing.
Your clients need to download an app
The problem
Trainerize requires clients to download and set up the Trainerize app to view workouts, track progress, or interact with their trainer. This adds friction, especially for less tech-savvy clients or those who don't want another app on their phone.
NForge's approach
NForge delivers programmes as professional PDFs and clients join live classes via a browser link. Zero friction, zero app downloads. Clients just click and go.
