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.
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.
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.
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.
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.
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
Progressive Overload
Automatically manages gradual load increases for continuous growth
Specificity Principle
Prioritizes hypertrophy-specific rep ranges (6-15 reps)
Individualization Principle
Addresses up to 10x genetic variation in response
Recovery & Supercompensation
Optimal rest suggestions integrated with sleep data
Variation
Prevents adaptation with stimulus changes every 4-6 weeks
Integrated Approach
Comprehensive optimization of training, nutrition, and recovery
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).
