What Is 5/20 Method Arm Workout
The 5/20 method is a specialized arm workout technique designed to enhance both muscle strength and endurance through progressive volume.
Here's a breakdown of how it works:
- 5 Reps: Begin with 5 repetitions using a challenging weight to build strength and power.
- 10 Reps: Increase the number of reps to 10, continuing with the same or slightly reduced weight to further boost endurance.
