# Cable Single Arm Bench Press - Canonical: https://fitwill.app/exercise/7932/cable-single-arm-bench-press/ - Media ID: 7932 - Primary muscle: Chest - Body part: Chest - Equipment: Cable Machine - Video: https://fitwill.app/videos/7932/cable-single-arm-bench-press.mp4 ## Description The Cable Single Arm Bench Press is a horizontal pressing movement performed lying on a flat bench positioned beside a cable machine, with the handle attached to a low pulley. Unlike a barbell or dumbbell press, the resistance comes from a cable that pulls your hand down and out toward the stack, so the tension never lets up and the direction of pull can be slightly adjusted to bias different fibers of the chest. Because you press one side at a time, your core has to resist rotation the whole time, which turns a familiar chest exercise into a subtle trunk challenge as well. This movement suits lifters who want constant tension on the pecs without loading the shoulder joint with a heavy free weight at the bottom of the rep. It works well as a secondary press after your main barbell or dumbbell work, or as a stand-alone chest builder on machines-only days. Because each arm works independently, it is also a practical way to expose and fix side-to-side strength differences that hide when you press with both arms together. The primary muscles worked are the pectorals, with the sternal head of the chest doing most of the driving as you press the handle up and in toward the midline. The triceps extend the elbow to finish each rep, the front delts assist the press, and the working-side serratus and lats help control the path. On the non-working side, and through your trunk, the obliques and deep core stabilize your ribcage so the pulling cable does not twist you off the bench. Setup matters here because the cable angle defines the whole exercise. Place the bench so the pulley sits roughly level with your lower chest when you lie down, and position yourself far enough from the machine that the cable starts with tension but does not drag your arm sideways at the bottom. Keep the working elbow tucked to roughly a 45-degree angle from your torso rather than flared straight out, which keeps the shoulder in a comfortable pressing groove. To execute well, lie back with your feet planted, brace your trunk, and start with the handle at chest level and your elbow bent. Press up and slightly across your body until the arm is extended over your chest, squeeze briefly, then lower under control until the elbow drops just below bench height. Exhale on the press, inhale on the way down, and avoid letting the weight stack yank your arm back at the end of each rep. Complete all reps on one side before switching. Practically, this exercise fits into hypertrophy programs as a moderate-rep accessory, into rehab-friendly upper body days because the load can be dialed down precisely, and into home or commercial gym sessions where a cable crossover station and an adjustable or flat bench are available. Keep the weight honest: if your hips twist or your shoulder rolls forward at the bottom, the stack is too heavy. ## Instructions 1. Set the pulley of the cable machine to its lowest position and attach a single handle. 2. Place a flat bench so that when you lie face up, the pulley lines up roughly with your lower chest and your head points away from the machine. 3. Sit on the bench, grip the handle with your near hand using a neutral or slightly turned-in palm, and lie back while pulling the handle into position at chest level. 4. Plant both feet flat on the floor, keep your non-working hand resting on your hip or thigh, and set your working elbow at about a 45-degree angle from your torso. 5. Brace your core and pull your shoulder blades gently down and back so your upper back stays in contact with the bench. 6. Press the handle up and slightly toward the midline of your body until your arm is extended over your chest, without locking the elbow hard. 7. Pause for a beat at the top and feel the chest shorten, then slowly lower the handle until your elbow drops just below the level of the bench. 8. Inhale as you lower, exhale as you press, and keep the motion smooth so the weight stack never slams between reps. 9. Finish all repetitions on one side, then reposition and work the other arm with the same setup and rep count. ## Tips & Tricks - If the cable pulls your arm outward at the bottom, slide the bench slightly away from the machine or lower your starting elbow position so tension begins from a stable spot. - The most common mistake is flaring the elbow straight out to the side; keep it near 45 degrees so the press follows the chest fibers instead of irritating the shoulder. - Do not let your torso roll toward the working side as you press. If your shoulder lifts off the bench, lighten the load and re-brace your obliques. - Keep a small bend in the elbow at the top rather than snapping into a locked-out arm, especially with higher cable loads. - Lower the handle under control for two to three seconds; the eccentric is where the cable's constant tension does most of its work on the chest. - Avoid letting the handle drift toward your face or stomach. Aim for a consistent landing spot at the outside of your chest on every rep. - Grip the handle firmly but not with a death grip; excess forearm tension often shows up as a shrug and steals work from the pecs. - If your wrist bends back under load, rotate your palm slightly toward your body so the handle sits flatter across your palm. - Start with your weaker arm first and match the reps on the stronger side to keep both sides progressing evenly. ## Frequently Asked Questions ### Which muscles does the Cable Single Arm Bench Press work? The pectorals are the primary movers, especially the sternal head as you press up and slightly across the body. The triceps and front delts assist, while the obliques and core stabilize your torso against the sideways pull of the cable. ### Is the Cable Single Arm Bench Press good for beginners? Yes, because the cable stack allows small, precise load increases and the bench supports your upper body throughout. Beginners should start light and focus on keeping the elbow at about 45 degrees and the torso flat on the bench. ### How should I position the bench for the Cable Single Arm Bench Press? Place the bench so the low pulley lines up roughly with your lower chest when you are lying down, close enough that the cable starts under tension. If the cable drags your arm sideways at the bottom, move the bench slightly farther from the machine. ### Why press one arm at a time instead of using both hands? Single-arm pressing reveals and corrects strength imbalances, and the cable's unilateral pull forces your core to resist rotation. That added trunk demand is something a two-arm barbell or dumbbell press does not provide. ### How heavy should I go on the Cable Single Arm Bench Press? Choose a weight you can press for controlled reps without your shoulders lifting off the bench or your hips twisting toward the stack. If form breaks in either of those ways, drop a plate or two and rebuild. ### What is the most common mistake in this exercise? Flaring the elbow straight out and bouncing the weight stack at the bottom. Keep the elbow near 45 degrees from your torso and lower the handle under control so the chest, not momentum, controls the rep. ### Can I substitute dumbbells if my gym has no low pulley? A single-arm dumbbell floor press or dumbbell bench press is the closest alternative. You lose the constant cable tension and the direction of pull, but the one-arm pressing pattern and anti-rotation demand remain similar. ### Is the Cable Single Arm Bench Press safe for the shoulders? For most people it is shoulder-friendly because the bench supports the arm and the load can be kept modest. Keep the elbow tucked closer to the body, avoid deep stretching past comfortable range, and stop if you feel pinching at the bottom. ### Where should the Cable Single Arm Bench Press fit in my workout? It works best as a secondary chest exercise after your main pressing lift, typically in the 8 to 15 rep range per arm. Finishing with it lets you fatigue the pecs under constant tension without maximal joint loading.
