Kaizer vs Askesis
Honest comparison between Kaizer and Askesis: adaptive AI, price, app, retention and nutrition. Both work great in Spanish, so language here is parity — the difference is what happens to the plan after every session your client logs.
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 over Askesis.
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.
A true native app for your clients.Askesis is a PWA — it installs from the browser, with browser push, no app store. It works, but it isn't a native app: your clients train in the Kaizer app for iOS/Android, polished and built for logging sessions fast. And as extra support, prices are shown in USD and charged in pesos (Askesis only bills in euros, 3€ per active client) — that removes friction at the door for your clients.
Retention driven by automation, 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. In Kaizer the AI does the adjustment work that's manual in Askesis — today with 1000+ trainers across 20+ countries and 120k+ routines generated. Plans stay alive: fewer plateaus, better adherence.
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.

You bill in pesos in LATAM instead of euros.

FAQ: Kaizer vs Askesis.
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 retention tracking. Current Kaizer pricing on kaizer.app/en/pricing.
They're at parity, and it's honest to say so: Askesis is a product developed in Spain, 100% in Spanish; Kaizer also offers the full product in Spanish (Rioplatense + neutral), plus English. Language shouldn't be the deciding factor between these two — the AI that re-programs weights and reps after every logged session, the native app and the retention that automation drives should be. Billing in pesos helps if your client base is in LATAM.
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.
