kaizen

kaizen is a running coach app that uses AI to create a training plan that bends to fit your life, not the other way around. Instead of a fixed schedule of specific workouts, it sets a weekly training load target based on your running history and goals. You can then meet that target however works best for you—whether that means a few long, easy runs or several short, hard sessions. The app analyzes your completed runs to track your fitness and adjusts future targets to keep you progressing safely toward your goal, even if you miss a workout or decide to run harder than planned.

What sets kaizen apart is its focus on consistency and adaptability. The core system is built on training load, a measure of the stress your runs place on your body. By monitoring this, kaizen can predict your race times and ensure you're building fitness without overdoing it. The app syncs with platforms like Strava to pull in your run data automatically. It’s designed for the real world, where work stress, busy weeks, and missed runs happen.

This tool is ideal for runners who find traditional, rigid plans demotivating or impossible to follow. It benefits anyone training for a race, from a 10k to a marathon, who wants a guided plan but needs flexibility. It’s also useful for runners who simply want to improve their general fitness with a structured yet adaptable approach. The app provides clear feedback on your progress and realistic predictions, helping you stay motivated by showing how consistent effort, not perfect adherence to a plan, leads to results.
