Kaizer — Your Personal Trainer

Kaizer is a fitness mobile application designed to make personal training more accessible, structured, and personalized. It brings workout planning, exercise tracking, trainer-client communication, and intelligent workout recommendations together in one seamless experience.

My role: Full product design and development.

I handled the end-to-end design and development of the mobile application, bringing together user experience, interface design, and functional implementation to create a complete fitness product.

Key features:

Personalized workout plans and structured training routines

Workout tracking for sets, reps, weights, and rest periods

Training history and progress monitoring

Trainer-client communication and workout adjustments

Personal trainer discovery and marketplace functionality

AI-powered workout generation and personalized exercise alternatives

Exercise library with visual muscle-group references

The goal was to create a practical, intuitive fitness experience that helps users stay consistent, understand their progress, and connect with personal trainers through a single application.
