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; Kaizer wins on automation, retention and a native app, scoped to training only.

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, as Kaizer does, so on that front they are at parity. And like Kaizer, it has full Spanish support that works great: language here is parity, not a Kaizer advantage.

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 switches it on or off per client, and any week they edit drops out of the calculation permanently.
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.

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.
Yes. Kaizer includes nutrition: calories and macros, meal plans and AI-assisted generation. Askesis bundles it at no extra cost too, so that one is parity and the difference goes back to training: Askesis' AI does not re-program weights and reps after every session.
