  Bench Press, and Deadlift.                                                                            
                                                                                            
  Stop guessing. Start getting stronger with data.

  WHY PEAK ADAPT                         
  ------------------------------------   

  [Visualize Fatigue. Train Smarter.]                                                                   
  Fatigue Index (FI) and Fatigue Stress Score (FSS), powered by the ACWR (Acute:Chronic Workload Ratio)
  model, help you prevent overtraining before it happens. Know instantly whether today is a day to push 
  hard or pull back.                       
                                                                                                        
  [Hypertrophy or Strength — Know Every Set]
  HP (Hypertrophy Potential) and SP (Strength Potential) scores show you in real time whether each set
  is building muscle or building strength. Train with purpose, not guesswork.                           
                                         
  [Automatic e1RM Tracking]                                                                             
  Just log your weight and reps — PEAK ADAPT calculates your estimated 1-Rep Max automatically. Watch
  your progress unfold on a 30-day trend graph.                                                         
           
  [Peak Prediction for Smarter Peaking]                                                                 
  Your training history predicts when you'll peak. Plan your competition or goal date with confidence,
  backed by your own data.                                                                              
           
  [Full Workout Control from Apple Watch]                                                               
  Start sets, end sets, and manage REST timers straight from your wrist. Post-workout HRV, resting heart
   rate, and sleep data are pulled automatically — so you always know your recovery status in real time.
           
  [DOTS Score: Fair Strength Comparison]                                                                
  Bodyweight and sex-adjusted scoring using the world-standard DOTS formula. See where you truly stand,
  regardless of weight class.
