BulkTrack Your Personal AI Coach for Scientific Muscle Growth

Why Choose BulkTrack

Evidence-Based Design for Muscle Hypertrophy

The only training app specialized for muscle growth, integrating over 500 research papers from 2020-2025. Maximizes your growth based on the scientifically proven optimal volume of 12-20 sets per muscle group per week (Schoenfeld et al., 2023).

AI Optimization for Individual Differences

Research shows up to 10x individual variation in muscle growth response to the same training. BulkTrack's AI analyzes your 4-week training data to determine your response type with 95% accuracy, providing a fully personalized program.

Sub-Second Fast Logging

Don't waste precious gym time. Industry's fastest recording system allows set entry in under 1 second. Stay focused on your training without interruption.

Key Features

AI Weight & Rep Suggestions

Analyzes your previous performance and RPE (Rate of Perceived Exertion) to suggest optimal weights considering fatigue. Automates progressive overload to ensure consistent progress every workout.

Auto-Optimization

Plateau Detection & Breaking Strategies

Automatically detects 3-week stagnation and suggests 4 evidence-based breaking strategies. Optimizes exercise selection, volume, and intensity adjustments to effectively break through plateaus.

Break Plateaus

Automatic Hard Set Calculation

Automatically counts "hard sets" (sets taken close to failure), shown by latest research (Baz-Valle et al., 2024) to have the highest correlation with muscle growth. Provides more accurate growth metrics than traditional volume calculations.

Latest Research

Muscle Group Heatmap

Visualizes weekly volume for 11 muscle groups, intuitively displaying optimal, insufficient, or excessive training. Instantly identify imbalances to build efficient training programs.

Visualization

Research Paper Integration System

Shows scientific evidence for all recommendations. Automatically fetches latest research from PubMed and Semantic Scholar, rating evidence levels on a 5-point scale. Ensures your training is always based on cutting-edge science.

Evidence

Complete Hands-Free Experience with Apple Watch

Dedicated Apple Watch app allows training with your phone in the locker. Record sets with a wrist tap and check recommended weights. Experience true hands-free training with 100% focus on your workout.

Implementing Cutting-Edge Hypertrophy Science

7 Evidence-Based Principles

01

Progressive Overload

Automatically manages gradual load increases for continuous growth

02

Specificity Principle

Prioritizes hypertrophy-specific rep ranges (6-15 reps)

03

Individualization Principle

Addresses up to 10x genetic variation in response

04

Recovery & Supercompensation

Optimal rest suggestions integrated with sleep data

05

Variation

Prevents adaptation with stimulus changes every 4-6 weeks

06

Integrated Approach

Comprehensive optimization of training, nutrition, and recovery

07

Reversibility Principle

Efficient comeback programs considering muscle memory

Scientific Evidence

Latest Research Implementation

RPE/RIR-based auto-regulation is proven 15% more effective than fixed programs (Helms et al., 2023). Individualized volume settings can yield 15% muscle cross-sectional area increase in 12 weeks. Furthermore, integrated approaches show 40% improvement in hypertrophy outcomes (Morton et al., 2024).
