Sam Sulek's Shoulder Pump: Side & Rear Delt Session

How to perform: Stand facing a cable machine with the handle attached to a high pulley. Grip the handle with one hand and take a step forward, turning your torso slightly so you can pull the cable across your body with a bent elbow. Focus on initiating the movement from the posterior deltoid and perform controlled horizontal abduction. Keep the shoulder joint stable and avoid rotating the torso.

Muscles worked, common mistakes, and benefits: Muscles worked include the rear deltoid (primary) with secondary activation of the posterior upper back and traps. Common mistakes include using momentum, rotating the torso, or letting the traps do the work; proper form is achieved by maintaining a fixed shoulder and isolating the arm movement. This exercise is ideal for improving rear delt shape and shoulder balance.

How to perform: Hinge at the hips with a flat back and a slight bend in the knees, holding a dumbbell in each hand. With palms facing each other or slightly rotated, raise the weights out to your sides in a controlled arc until your arms are roughly parallel to the floor. Lead with the elbows and keep movement strict — avoid recruiting the traps by keeping the shoulder blades relatively neutral and the neck relaxed.

Muscles worked, common mistakes, and benefits: Primary muscles worked are the rear deltoids with secondary engagement of the upper back. Common mistakes include swinging the weights, lifting too heavy which shifts load to the traps, and rounding the spine. Proper form maximizes posterior delt activation and helps develop rear shoulder thickness and separation.

How to perform: Sit upright on a bench with a dumbbell in each hand at your sides. Keeping a slight bend in the elbow, raise the dumbbells out to the sides until the arms reach shoulder level. Pause briefly at the top for a peak contraction, then lower under control. Maintain an upright torso and avoid shrugging the shoulders up toward the ears.

Muscles worked, common mistakes, and benefits: Muscles worked include the lateral deltoid (primary) and anterior deltoid as a minor secondary contributor. Common mistakes are using momentum, leaning back, or excessively shrugging—proper form ensures isolation of the middle deltoid and helps widen the shoulder line for better proportion and peak when posing.

How to perform: Adjust the machine so the pads line up with the outside of your arms while seated. Press your arms out laterally against the pad using controlled motion until you reach full lateral contraction, then slowly return to the start. Use a weight that allows you to feel the side delts without leaning or using momentum.

Muscles worked, common mistakes, and benefits: Muscles worked are the lateral deltoids primarily with minor trap involvement. Common mistakes include using excessive torso momentum or too-heavy loads that shift focus away from the delts. This machine is an excellent finisher for achieving a dense pump and consistent tension throughout the set.

How to perform: Use a recumbent (seated) bike at moderate-to-high resistance and maintain a steady cadence for the session duration. Focus on consistent breathing, relaxed upper body posture, and covering the display to avoid clock-watching. Aim for a sustained effort that feels challenging but sustainable for 45 minutes.

Muscles worked, common mistakes, and benefits: This is primarily a cardiovascular endurance activity; lower-body musculature (quads, hamstrings, glutes) is engaged. Common mistakes include constantly checking the clock which can make the session feel longer, and using improper seat setup that causes knee or back discomfort. Steady-state cardio aids conditioning and supports pre-competition conditioning or fat-loss phases.
