An arm blaster is a simple yet effective fitness tool designed to isolate your bicep and tricep muscles during curls and extensions by locking your elbows in a fixed position against your torso. This prevents you from using momentum or "cheating" with other muscle groups, ensuring all the work is done by your arms. Benefits of an arm blaster

Isolation: Forces your biceps to do all the work by eliminating the use of your shoulders and back to lift the weight. Reduces Cheating: Prevents momentum-based lifting, ensuring every rep is effective.

Mind-Muscle Connection: The fixed position helps improve your awareness and connection with the bicep muscles during the exercise.

Progressive Overload: By ensuring strict form, it helps you focus on increasing muscle size and strength through quality training.

Arm blasters are a great tool for bodybuilders and experienced lifters looking to intensify their arm workouts, though they may not be recommended for absolute beginners who should focus on foundational movements first.
