How your personalized training plan works

  1. Initial diagnosis — You do a 400m and 200m freestyle test. We calculate your CSS and reference paces for each intensity zone.
  2. Structured block-based plan — 4-to-8-week blocks with real progression. Each session: warm-up, technique, main set, complementary and cool-down.
  3. Clear paces and goals — Each set indicates rest and exact pace based on distance and effort zone. You know what to do, how, and at what speed.
  4. AI that learns from every session — You log paces and effort. The AI analyzes your performance and proposes automatic adjustments.

Frequently asked questions

What is a personalized swimming training plan?

A program designed for your level, goals and availability. It calculates paces based on your actual times, structures each session with logical progression and adapts volume and intensity week after week.

How can I improve my swimming times?

Training with structure and specific paces per intensity zone. A plan with block-based progression (4-8 weeks), organized sessions and real performance tracking.

What are intensity zones in swimming?

Effort ranges based on your CSS: from light aerobic zone to anaerobic zone. Each zone works a different energy system.

Do I need a coach to improve?

Not necessarily. Swimer generates plans with the same professional logic. And if you have a coach, log your workouts manually.

What is CSS (Critical Swim Speed)?

Your sustainable swimming speed, equivalent to your aerobic-anaerobic threshold. Calculated from your 400m and 200m freestyle times.
