text: I squat 3x weekly. 
  
  At 75, I train for intensity and focus. 
  
  So, right now - always - 50 squat reps, 155# and I only increase weight as I decrease sets to a chosen goal.  
  
  Two sessions ago 17 sets. On Monday 8 sets. 
  
  I will increase weight when I can to 5x10. 
  
  Between sets calf work.
