Let's talk about your "pack-a-punch" posterior deltoids, AKA your rear delts. These muscles hang out in the back of your shoulder, originating on the spine of your shoulder blade and latching onto your upper arm bone.
They help extend your shoulder, and these babies are also responsible for externally rotating it. So next time you show off your guns at the gym, remember to give a little love to your rear delts for their behind-the-scenes work.
Do you remember Arnold Schwarzenegger, renowned bodybuilder and former Governor of California? He says:
"If you want to build rear deltoids, you must train them like any other body part. You cannot just focus on one group of muscles and ignore the rest. Always keep in mind that variations are essential for a well-rounded physique."
~Arnold Schwarzenegger

What Are Rear Deltoids?
Don't worry: they're not some new designer drug. They're the muscles in the back of your shoulders! They start from the spine of your shoulder blade and connect to your upper arm bone, aka humerus. Think of them as your wingmen for shoulder action.
Your deltoids are the dynamic duo that helps to extend and externally rotate your arm, alongside the trusty infraspinatus and teres minor muscles of your rotator cuff. In simpler terms, these guys are essential for smooth and efficient shoulder movement. Without deltoids, you might be a T-rex trying to high-five. So give your shoulder muscles a pat on the back (or wherever they are) for their impressive contribution to your mobility.
Okay, so you've got the 411 on those sneaky little muscles in the back of your shoulders. But what good is knowledge without action? Let's dive into some killer exercises that'll whip those rear delts into shape. No excuses it's time to train like a boss!

FAQs
1. What do Rear Delts do?
The posterior deltoid is responsible for the shoulder's extension, external rotation, and horizontal abduction. To stretch this muscle, reverse the action by the shoulder joint's internal rotation, flexion, and horizontal adduction.
2. How many sets should you do for rear delts?
This question has no perfect answer since everyone's physiology is different. However, 3-4 sets of 12-15 repetitions are good starting points. You can experiment with different numbers of sets and reps to see what works best for you.
3. Do rear delts respond better to high or low reps?
This question has few answers because it depends on the person's physiology and how their muscles respond to various stimuli. Generally speaking. However, when training their rear delts, most people get better results using high reps. High reps are more effective at stimulating muscle growth and hypertrophy.
