Exercise programming is the systematic design of structured fitness routines tailored to individual goals (strength, muscle growth, endurance, fat loss), constraints (age, injuries, equipment), and preferences. It combines exercise selection, rep/set schemes, rest periods, and periodization to create adaptable workouts that prevent plateaus and injuries. A structured program tells you which exercises to do, how many reps/sets, how much weight, and how long to rest between sets. The contrast: most people guess ("do 3 sets of 10 of whatever") versus those with intentional programs who see measurable progress every 4 weeks.
