1. Inspiration & Target Market

The inspiration behind PT plus arises from a common issue: people often struggle to train correctly without a personal trainer. Incorrect form can lead to injuries, slow progress, and frustration, but hiring a personal trainer is costly, typically ranging from $50 to $100 per session.

At the same time, home fitness is booming. Despite the availability of fitness apps, YouTube workouts, and virtual training, users still lack real-time feedback essential for safe and effective training.

We aim to bridge this gap with AI-powered posture correction and personalized workout plans, providing real-time feedback akin to human trainers, at a fraction of the cost.

Target Market:

Home fitness users – Prefer workouts at home over gym memberships.
Gym-goers – Seek AI-based real-time feedback without trainer costs.
Beginners & intermediate users – Require guidance for proper form and structured workout plans.
Corporate wellness & gyms – Businesses and fitness centers aiming to enhance offerings with AI technology.

Our mission is to make PT plus the go-to virtual personal trainer for everyone, from beginners to seasoned athletes.
