Major Muscle Groups

Note: Decided to lost fat and get lean. Take up some PT session. My PT told me that there are 7 major muscle groups. However, who would have taken notes during PT session. Hence, I did a search on the internet to get a better picture for my own revision. And these is how I have grouped it. Reference at your own risk.

1. Deltoids (Shoulder)
• Anterior Deltoid (front of shoulder)
• Lateral Deltoid (side of shoulder)
• Posterior Deltoid (back of shoulder)
2. Biceps (upper arm front)
3. Triceps (upper arm back)
4. Pectoralis (Chest)
5. Back

6. Abdominal (Abs)
