Charles Glass’ Lateral Raise Machine Tips for Shoulder Balance and Stability
In the Instagram post, Glass emphasized that the lateral raise machine can help isolate the side delts to build wider, more capped shoulders.
“The lateral raise machine is one of the best ways to isolate the side delts and build wider, more capped shoulders. Strong side delts help create that broad upper body look while also improving shoulder balance and stability 💪”
For optimal results, he recommended constant tension on the delts with controlled repetitions.
“Focus on controlled reps, keeping tension on the delts, and avoiding momentum so the shoulders do all the work. Proper form and consistent tension make all the difference when training delts 🔥”
His form tips were straightforward: lean in and push the arms open while focusing on the side delts.
“Lean in and push open,” explained Glass. “You can do it without the handles, but you’ve got to turn the elbow. It’s harder, right? Depending on where you put your arms, if you’re doing this [out to the side], that’s as high as you’re going to get your arms to go anyway. So, when you’re pushing it, you push and make sure you feel the side.”
“Don’t bend the wrist, straighten it out,” he advised. “When you bend your wrist, you end up taking your elbows off the pad. Straighten it out, and it stays on.
This wasn’t Charles Glass’ first shoulder training breakdown. He recently walked through an intense shoulder workout to build size, roundness, and strength. During the session, he urged for strict form, especially on dumbbell side lateral raises.
As one of the most decorated coaches in the sport, Glass’ tips are backed up by real-life experience. He stands by the lateral raise machine, stressing its effectiveness for building the side delts.
