Match Each Exercise To Its Corresponding Muscle

Match Each Exercise to its Corresponding Muscle: A Comprehensive Guide

Knowing which muscles are activated by specific exercises is crucial for building an effective workout routine. This comprehensive guide will detail numerous exercises and their corresponding target muscles, helping you optimize your training for maximum results. We’ll delve into the primary muscles worked, secondary muscles involved, and variations that emphasize different muscle groups. Understanding this connection is key to achieving your fitness goals, whether it's building strength, increasing muscle mass, or improving overall fitness.

• Secondary Muscles: Trapezius, rhomboids, forearms.

3. Bent-Over Rows (Barbell or Dumbbell):

• Primary Muscles: Latissimus dorsi, trapezius, rhomboids.
• Variations: Barbell rows, dumbbell rows, T-bar rows.
• Secondary Muscles: Biceps brachii, forearms, erector spinae.

4. Seated Cable Rows:

• Primary Muscles: Latissimus dorsi, rhomboids, trapezius.
• Variations: Varying grips and hand positions can target different areas of the back.
• Secondary Muscles: Biceps brachii, forearms.

Shoulder Exercises and Targeted Muscles

The shoulder complex involves the deltoids (anterior, medial, and posterior), rotator cuff muscles (supraspinatus, infraspinatus, teres minor, subscapularis), and trapezius.

• Primary Muscles: Anterior deltoids, medial deltoids, triceps brachii.
• Variations: Arnold press (external rotation during lift), seated overhead press, behind-the-neck press (can put stress on shoulders, use cautiously).
• Secondary Muscles: Trapezius, upper pectoralis major.

2. Lateral Raises (Dumbbell or Cable):

• Primary Muscles: Medial deltoids.
• Variations: Dumbbell lateral raises, cable lateral raises.
• Secondary Muscles: Trapezius, supraspinatus.

3. Front Raises (Dumbbell or Cable):

• Primary Muscles: Anterior deltoids.

• Secondary Muscles: Quadriceps, forearms, traps.

4. Leg Press:

• Primary Muscles: Quadriceps, glutes, hamstrings.
• Variations: Adjusting foot placement can emphasize different muscle groups.
