The Science Behind HyperTrack
We didn't just build another workout logger. We encoded decades of exercise science and nutrition research into AI-powered algorithms that optimize your training, diet, and recovery in real-time.
The Problem with Most Workout Apps
They're Just Digital Notepads
Log your sets, see a chart, repeat. No intelligence, no optimization, no understanding of WHY you're doing what you're doing.
Random Workout Generators
Some apps generate workouts, but without understanding periodization, fatigue accumulation, or your specific needs. It's fitness roulette.
One-Size-Fits-All Volume
"Do 3x10 for everything" ignores that muscles respond differently, people recover differently, and goals require different approaches.
Features That Actually Matter
AI-Powered Mesocycle Planning
Unlike basic workout trackers, HyperTrack uses intelligent algorithms to design periodized training programs tailored to your goals, experience, recovery capacity, and available time.
How it works: We analyze your training frequency, session duration, experience level, sleep quality, and stress to recommend the optimal split, volume distribution, and periodization model.
AI Coaching & Personalized Notes
Get real AI-powered coaching advice before every workout. Our system analyzes your history, body composition, and current mesocycle phase to give context-aware guidance.
How it works: Using Claude AI, we generate personalized coach notes that consider your workout type, week in mesocycle, recent performance, body composition goals, and training history—like having a knowledgeable coach in your pocket.
AI-generated coaching is informational and educational. It is not a substitute for professional coaching, medical advice, or personalized training supervision.
Complete Nutrition Tracking
Track your nutrition with our integrated food database powered by USDA FoodData Central. Log meals, scan barcodes, calculate macros, and auto-adjust targets as your body changes.
How it works: Search 300,000+ foods from the USDA database. Use our smart macro calculator that factors in your goals, activity level, and even GLP-1 medications. Your macro targets automatically recalculate when you log new weight.
Nutrition recommendations are general guidelines based on common research-backed approaches. They are not medical or dietitian advice. Consult a healthcare provider for personalized nutrition guidance.
Auto-Regulation & Fatigue Management
Our fatigue budget system tracks both systemic (CNS) and local muscle fatigue, adjusting your workout in real-time.
How it works: Each exercise has a fatigue "cost". Compounds cost more (8-12 points) than isolations (3-5 points). When your weekly budget depletes, we suggest deloads before you burn out.
S-Tier Exercise Selection
Not all exercises are created equal. Our database rates every exercise by hypertrophy effectiveness (S/A/B/C tier) based on Stimulus-to-Fatigue Ratio.
How it works: When building your mesocycle, we prioritize S-tier exercises (high stimulus, low fatigue) like cable work and machines, especially later in mesocycles when fatigue accumulates. Compounds are reserved for when you're fresh.
Smart Rep Range System
Rep ranges adapt based on muscle fiber type dominance, exercise position in workout, periodization phase, and your experience level.
How it works: Fast-twitch muscles (hamstrings, triceps) get 4-8 reps. Slow-twitch (calves, delts) get 12-20. Mixed-fiber (chest, back) get 8-12. Compounds start workouts heavier; isolations finish lighter.
DEXA Tracking & FFMI Analysis
Track body composition scans over time. Calculate your Fat-Free Mass Index to see where you stand against natural limits.
How it works: Enter your DEXA scan data (or estimates). We calculate FFMI (Lean Mass / Height²) and compare you to natural benchmarks (21-25 range). AI coaching suggests bulk, cut, or recomp.
FFMI analysis and body composition metrics are informational tools, not medical assessments. Natural limit estimates are based on population studies and may not apply to every individual.
GLP-1 & Peptide Support
On Ozempic, Mounjaro, or other GLP-1 medications? Our macro calculator adjusts protein targets to prevent muscle loss during aggressive cuts.
How it works: Select your medication and we automatically increase protein recommendations (up to 1.2g/lb) and allow larger caloric deficits while keeping you in a safe, muscle-preserving range.
This feature provides nutrition guidance for those already prescribed GLP-1 medications by their doctor. It is not medical advice. Always follow your healthcare provider's instructions and discuss dietary changes with them.
Reactive Deload Detection
HyperTrack monitors performance trends, sleep quality, motivation, and joint health to automatically suggest deloads before you overtrain.
How it works: If RPE consistently hits 9.5+, sleep drops below 2/5, or you miss rep targets for 2+ sessions, we trigger an early deload instead of waiting for a fixed schedule.
E1RM Tracking & Plateau Detection
Track estimated one-rep max trends for every exercise. Our algorithms detect stagnation early and suggest interventions.
How it works: Using the Brzycki formula, we calculate E1RM from every working set. When your E1RM flatlines for 3+ sessions, we flag a plateau and suggest exercise swaps or intensity techniques.
Built on Real Science
Our features are informed by peer-reviewed research and established training methodologies. See citations below.
Volume Landmarks (MEV, MAV, MRV)
Renaissance PeriodizationMEV (Minimum Effective Volume) is the least you need to grow. MAV (Maximum Adaptive Volume) is the sweet spot for gains. MRV (Maximum Recoverable Volume) is the ceiling—go beyond it and you regress.
Citation: Israetel, M., Hoffman, J., Smith, C. (2015). Scientific Principles of Strength Training. Renaissance Periodization.
In HyperTrack: We track your weekly sets per muscle and keep you in the productive zone—typically 10-20 sets/week for most muscles, adjusted for your recovery capacity.
Stimulus-to-Fatigue Ratio (SFR)
Renaissance PeriodizationNot all exercises are equal. A machine fly gives great chest stimulus with minimal fatigue to recover from. A barbell bench press stimulates chest but also taxes shoulders, triceps, and CNS.
Citation: Israetel, M. (2017). Training Volume Landmarks for Muscle Growth. Renaissance Periodization.
In HyperTrack: When building your program, we prioritize high-SFR exercises (machines, cables, isolation work) later in mesocycles when fatigue is high, saving low-SFR compounds for when you're fresh.
Evidence-Based Protein Requirements
Peer-Reviewed ResearchA meta-analysis of resistance training studies found that gains in fat-free mass and strength plateaued beyond approximately 1.6 g/kg/day total protein intake, with confidence intervals extending to ~2.2 g/kg/day.
Citation: Morton, R.W., et al. (2018). A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults. British Journal of Sports Medicine, 52(6), 376-384. [DOI]
In HyperTrack: Our macro calculator uses 1g/lb (2.2g/kg) as a starting point, which is consistent with this research. Higher intakes may be used when supported by individual goals and preferences.
Muscle Fiber Type & Rep Ranges
Exercise PhysiologyDifferent muscles may have varying proportions of fast-twitch (explosive, fatigable) and slow-twitch (endurance, resistant) fibers. Research suggests a wide rep range (6-20+) can be effective for hypertrophy.
Citation: Schoenfeld, B.J., et al. (2021). Resistance Training Recommendations to Maximize Muscle Hypertrophy in an Athletic Population. International Journal of Strength and Conditioning, 1(1). [DOI]
In HyperTrack: We program varied rep ranges: typically lower reps (4-8) for posterior chain work, moderate (8-12) for mixed-fiber muscles, and higher (12-20+) for slow-twitch dominant muscles, while acknowledging individual variation.
Autoregulation with RPE/RIR
Strength & ConditioningRPE (Rate of Perceived Exertion) and RIR (Reps in Reserve) allow training to appropriate intensity based on daily readiness, rather than fixed percentages that may not account for recovery state.
Citation: Helms, E.R., et al. (2016). Application of the Repetitions in Reserve-Based Rating of Perceived Exertion Scale for Resistance Training. Strength & Conditioning Journal, 38(4), 42-49. [DOI]
In HyperTrack: We guide progression through RIR: start mesocycles conservatively at 3 RIR, progress to 1 RIR, with final sets potentially reaching 0 RIR. This systematic approach helps manage fatigue.
Energy Balance & Metabolic Adaptation
Nutrition ResearchTotal Daily Energy Expenditure (TDEE) includes basal metabolic rate, activity, and exercise. During prolonged caloric restriction, metabolic adaptation can reduce TDEE. Regular monitoring helps adjust targets.
Citation: Trexler, E.T., Smith-Ryan, A.E., & Norton, L.E. (2014). Metabolic adaptation to weight loss: implications for the athlete. Journal of the International Society of Sports Nutrition, 11(1), 7. [DOI]
In HyperTrack: Our calculator estimates TDEE from your stats and activity level. When you log new weight, we can help recalculate your targets to support continued progress.
Periodization Models
Training SciencePeriodization involves systematically varying training variables over time. Research comparing linear and daily undulating models found both produce similar hypertrophy outcomes when training volume is equated.
Citation: Grgic, J., et al. (2017). Effects of linear and daily undulating periodized resistance training programs on measures of muscle hypertrophy: a systematic review and meta-analysis. PeerJ, 5, e3695. [DOI]
In HyperTrack: Our mesocycle builder incorporates periodization principles to help vary intensity and volume across training phases for sustainable progress.
Progressive Overload
Fundamental PrincipleProgressive overload—gradually increasing training demands—is a foundational principle for continued adaptation. This can involve increasing weight, reps, sets, or improving technique over time.
Citation: Schoenfeld, B.J. (2010). The mechanisms of muscle hypertrophy and their application to resistance training. Journal of Strength & Conditioning Research, 24(10), 2857-2872. [DOI]
In HyperTrack: We track progression over time and suggest incremental increases when performance indicates readiness, such as adding 1-2 reps or modest weight increases when you hit target rep ranges with good form.
