Project Overview

Digitizing training routines for enhanced performance and sustainability

Super Weightlifting is a digital platform tailored for strength athletes and fitness professionals. It offers personalized training programs, real-time tracking, and efficient communication between users and coaches. The platform fills a crucial market gap: a scalable, customizable, and interactive app that replaces inefficient paper-based methods of workout tracking.

The client initially approached Linnify with a rigid version of the mobile app. Together, we transformed it into a flexible, engaging tool that empowers both coaches and athletes through tailored routines, in-app video guidance, and expanded features that support consistent performance growth.

Industry challenges

The strength training and fitness coaching industry has long relied on outdated methods such as paper logs, static spreadsheets, and manual communication between coaches and athletes.

These traditional processes often result in inefficiencies, limited scalability, high administrative burdens, and inconsistent tracking of progress. Additionally, the lack of personalization and real-time feedback makes it difficult for athletes to optimize their performance or for coaches to support a growing client base effectively.

Cultural considerations

By addressing the specific needs of Romania’s strength training community, the app aligns closely with regional fitness practices, coaching styles, and user behaviors. As the app matures, there is potential to scale its impact across other European markets with similar athletic and coaching dynamics.

Problem

Target icon

Client's challenge

Athletes and coaches often rely on outdated, manual systems to track progress, such as paper notebooks or spreadsheets. These methods are time-consuming, prone to data loss, and difficult to customize on the go. The key pain points addressed include:

  • Lack of real-time feedback and progress visibility
  • Manual documentation that is time- and resource-intensive
  • Inefficient communication between coaches and athletes
  • Limited adaptability in training plans
  • Data security and compliance concerns

The original app version lacked scalability and flexibility.Coaches couldn’t easily modify or duplicate training plans, users couldn’t interact with video feedback or dynamically adjust their weights/reps, and administrative tasks required time-consuming manual inputs.

The rigidity of the solution limited its usefulness and ability to grow a community around the product.

Solution

Proposed solution

The Super Weightlifting App replaces outdated, paper-based tracking with a mobile platform that offers real-time personalization, coach feedback, and progress monitoring.

Linnify partnered with the client to reimagine Super Weightlifting as a robust mobile and web application. We focused on building custom functionalities that address core user pain points and enable the business to grow.

The app solves major fitness industry challenges by eliminating paperwork, increasing data accuracy, and enabling scalable, personalized training for both amateur and professional athletes.

Key product improvements include:

  • Real-time customization: Users can edit weights and reps after each set to better reflect personal performance.
  • Video guidance: Users can preview and upload videos for proper exercise execution and coaching feedback.
  • Custom dashboard: Admins can manage training programs with features like drag-and-drop, program duplication, status filtering, and streamlined video uploads.
  • Online Coaching: Personalized programs are shared via deep links, streamlining communication between coach and athlete.
  • Subscription management: Integrated with Stripe and RevenueCat, including multi-tiered plans and discount codes.
  • Web presence: A professional website provides access to subscription info, training program overviews, and user accounts.

These additions not only improved user experience but enabled the client to better support subscribers, scale the business model, and reduce operational bottlenecks.
