- Lower rep ranges (3-6 reps) for strength gains and muscle growth.
- Varied rep ranges for a more challenging workout and to keep your muscles guessing.
For example, you may use higher rep ranges for exercises like the feet-elevated dumbbell fly and incline dumbbell press with feet on bench, and lower rep ranges for exercises like the cable fly.
Progressive Overload and Periodization
Progressive overload refers to the gradual increase in weight or resistance used in a workout routine over time. This is essential for muscle development, as it allows your muscles to adapt to the demands placed on them. Periodization involves varying the intensity and volume of your workouts to avoid plateaus and promote continued progress. To effectively periodize your workout routine, consider the following strategies:
- Increase the weight or resistance used in each exercise over time.
