WHY

Why look for a Trainerize alternative.

Trainerize works well if you coach 100% in the US in English. If your base is LATAM, you're missing: native Rioplatense Spanish, local billing in pesos, automatic weight/rep adaptation after every session and LATAM-hours support. Here are the 5 best alternatives, ranked by compatibility with Spanish-speaking coaches.

FAQ

FAQ about Trainerize alternatives.

Kaizer. Built from scratch in Rioplatense Spanish, shows prices in USD and charges in pesos, automatically adjusts weights and reps after every session the client logs (Trainerize doesn't) — something no other alternative to the English leader does well.

Kaizer has a Free plan forever, up to 3 clients, no card. Trainerize offers a 30-day trial but requires a card. For coaches starting with few clients, Kaizer's Free plan is the only real no-recurring-cost option.

Only Kaizer. Trainerize, Harbiz, TrueCoach, Hevy Coach and My PT Hub all generate static routines (some with AI, some without). Kaizer is the only one running a weekly agent that reviews client performance and proposes specific adjustments. The AI is optional — turn it off anytime; you keep the final say.

Today none of the options on this list truly cover gyms. At Kaizer, the gym model — multi-coach dashboard, multi-location and MAU-based pricing — is on our roadmap, not available yet; today we are focused on personal trainers. The rest (Harbiz, TrueCoach, Hevy Coach, My PT Hub) also lack a serious B2B2C product for gyms.

Zero. Our team migrates all your data for you (clients, routines, history) in under 48 hours — no CSV exports, nothing to upload by hand. Kaizer has a Free plan up to 3 clients to try risk-free, and Trainerize has no lock-in.
