Training that reads your recovery

Havik measures the load, readiness, and performance behind every session — then adjusts your plan from what actually happened, not what was scheduled.

Developed by a personal trainer and a co-founder with a BSc in Sport and Exercise Science who is pursuing an MSc in Strength and Conditioning.

See the decision, not just a score

The real Today screen puts readiness next to the exact session it can affect. When there is something actionable, Havik shows the bounded dose change or asks you to review a recommendation. The session’s purpose stays visible, and you can keep the original.

Why Havik exists
01 · The original problem

Training for more shouldn’t mean losing what you’ve built.

“I wanted to train for a marathon without treating strength and hypertrophy as collateral damage.”

Havik began with a problem its founder—a personal trainer and strength coach—was trying to solve for himself. While preparing for a marathon, he wanted the endurance to cover 26.2 miles without giving up the strength and muscle he had spent years building.

The marathon plan was only one part of the puzzle. Long runs, quality sessions, heavy lifting, fatigue, recovery, and a changing schedule all had to work together. Most training apps could track each piece. Very few could reason across all of them.

What began as a way to manage one complicated hybrid plan grew into a personalized training system. Together with a co-founder who holds a BSc in Sport and Exercise Science and is pursuing an MSc in Strength and Conditioning, Havik combines research, lived coaching judgment, and each athlete’s own training evidence.

The role of AIPersonalize the logic—not replace the thinking beneath it.

Goals, training history, schedule, equipment, performance, and recovery shape what Havik recommends next.

Inspect the week before you train it

The real plan detail keeps each phase, checkpoint state, and training day in one view. Open a session to see the actual exercise prescription, then start today’s workout without losing the week around it.

Choose a phase or expand a training day.

Complete the remaining sessions. Progression resolves after supported execution, performance, and recovery evidence are available.

One surface, four different evidence models

The actual Progress interface changes with the sport. Strength gets lift authority and rep curves; endurance gets the thresholds, zones, execution, and efficiency measures that belong to that discipline.

Why did Tuesday's tempo feel so hard?

9:42 AM

Your recent load was elevated and readiness sat below your baseline. Tuesday's heart-rate response was also higher than your recent tempo sessions.

9:42 AM

Should I still race Sunday?

9:43 AM
Chat with Coach

A coach that already has your numbers

Ask why a session felt hard and it can see your readiness, recent load, and the heart-rate data for that exact workout. The conversation starts with context instead of a questionnaire — and it can rebuild the plan when your life changes.
