QUICK ANSWER

In one sentence.

Askesis is a very solid Spanish platform for strength coaches, 100% in Spanish, with rock-bottom transparent pricing (3€ per active client, 60-day trial). It's honest to say Spanish is at parity with Kaizer — that's not the differentiator. The real difference is the AI: Askesis tracks RPE/RIR, tonnage and estimated 1RM, but the coach adjusts every routine by hand. Kaizer takes every session the client logs and re-programs weights and reps automatically (recalculating estimated 1RM via NSCA tables), with the coach always keeping the final say. Add a native app and billing in pesos for LATAM. Askesis wins on small-roster price and bundles nutrition; Kaizer wins on automation, retention and a native app, scoped to training only.

WHERE KAIZER WINS

Four reasons to pick Kaizer over Askesis.

Each point ties back to a concrete limitation of the compared product.

The AI re-programs itself, it doesn't just track.

Askesis has excellent strength primitives — TOP SET, BACK OFF, RPE/RIR, tonnage, estimated 1RM — but all of that is for YOU to read and adjust by hand. The only AI in the product is for nutrition, not training. Kaizer takes every session the client logs, recalculates the estimated 1RM with NSCA tables, and re-programs the weights and reps of upcoming sessions. You choose whether it runs unattended or as a suggestion to approve. The difference between editing 30 routines every Monday and reviewing suggestions.

Native app and billing in pesos for LATAM.

Askesis is a PWA — it installs from the browser, with browser push, no app store. It works, but it isn't a native app. And its pricing is in euros: 3€ per active client, with no local payment rails for LATAM. Kaizer runs as a native iOS/Android app for your clients, shows prices in USD and charges in pesos. For a coach in Argentina, Mexico or Colombia, that removes friction at the door.

Retention measured, not just promised.

Askesis writes about client retention on its blog, but ships no automation that drives it: re-progression depends on the coach editing by hand. Kaizer cites -50% churn (92% retention) and 15 hrs/week saved, precisely because the AI does the adjustment work that's manual in Askesis. Fewer plateaus, better adherence.

WHERE ASKESIS WINS

Where Askesis is the right call.

Askesis genuinely wins on price and on strength-specific depth in the Spanish market. At a flat 3€ per active client, with no add-ons, no setup fee, white-label included and a 60-day free trial, it's one of the cheapest and most transparent options for a Spain-based strength coach — and it's often cheaper than Kaizer for small rosters once tiers are factored in. Its programming primitives (TOP SET / BACK OFF set types, native RPE/RIR, tonnage, estimated 1RM) are purpose-built for powerlifting and hypertrophy. It also bundles a nutrition module with AI-assisted diets at no extra cost — something Kaizer deliberately does not offer. And like Kaizer, it has full Spanish support that works great: language here is parity, not a Kaizer advantage.

Not for training. The only AI feature in Askesis is personalized diet creation (nutrition). Routine programming is manual: it tracks RPE/RIR, tonnage and estimated 1RM, but the coach adjusts weights and reps by hand session by session. Kaizer takes every workout the client logs, recalculates the estimated 1RM with NSCA tables, and re-programs the weights and reps of upcoming sessions automatically; the coach approves or lets it run unattended.

At small scale, usually yes — and it's fair to say so: Askesis charges 3€ per active client, with no tiers, no setup fee and white-label included. For a small roster it tends to be cheaper than Kaizer. What Kaizer adds in return is automatic AI re-progression, a native app, billing in pesos and measured retention.

They're at parity. Askesis is a product developed in Spain, 100% in Spanish with Spanish support; Kaizer also works perfectly in Spanish (Rioplatense + neutral) with a team in Buenos Aires. Language shouldn't be the deciding factor between these two — adaptive AI, the native app and billing in pesos for LATAM are.

Askesis is a PWA: it installs from the browser on mobile and desktop, without going through the app store, and uses browser push. It works well, but it isn't a native app. Kaizer runs as a native iOS and Android app for your clients.

No, by design. Askesis includes a nutrition module (calories, macros, AI-assisted diets) at no extra cost. Kaizer is focused on training programming only — it doesn't promise macros or meal plans. If you need nutrition built into the same tool, that's a genuine advantage for Askesis.

Yes — and you don't do it alone: you export your roster and programming from Askesis (or give us access) and our team recreates the routines and migrates clients and history in under 48 hours. The key upgrade is that, once migrated, Kaizer's AI takes over the per-session re-progression you were doing by hand in Askesis — you keep the final say.
