For leg days this program:
We are keeping same weight for squats for 2 weeks then as reps decrease your weight will increase.
Example:
Week 1-2: 12 reps at 45 pounds
Week 3-4: 10 reps at 65 pounds
Week 5-6: 8 reps at 85 pounds
Week 7-8: 4-6 reps at 100 pounds
(Of course these are guessed numbers, you can increase 5 pounds every two weeks or 10, etc. whatever works best for you. The goal is to challenge yourself and up weight at least some)
