Bench Press Mistakes: The 9 Most Costly Technical Errors, Why Each Limits Performance or Causes Injury, and Exactly How to Fix Them

Updated 2026  |  By Team Genghis Fitness  |  24 min read

The bench press is the most popular upper body exercise in strength training worldwide, and it is performed incorrectly by the majority of athletes who use it. This is not a minor concern: the technical errors that are most common in the bench press are not just inefficiencies that reduce performance, several of them are direct causes of the shoulder injuries that sideline bench pressers for months or years. Understanding exactly what goes wrong in the bench press, why each error matters mechanically, and the specific correction for each gives every athlete a clear path from whatever technical standard they currently have to a bench that produces maximum performance with minimum injury risk.

Mistake 1: Bar Path Goes Straight Down to Mid-Chest

The intuitive bar path for the bench press is straight down to the mid-chest and straight back up. This is mechanically inefficient and places the shoulder joint in an impingement-prone position. The correct bar path descends in a slight J-curve: the bar comes down to the lower chest (near the base of the sternum or nipple line) and presses back to a point over the upper chest, not directly back to the starting point above mid-chest. This J-curve keeps the shoulder joint in a mechanically advantageous position throughout the lift.

Research on bar path kinematics published in the Journal of Strength and Conditioning Research confirmed that elite bench pressers use this curved bar path consistently and that it produces higher force output with lower joint stress than the straight vertical path used by less experienced lifters. Fix: focus on lowering the bar to the lower chest and pressing toward the uprights diagonally rather than straight up.

Mistake 2: Elbows Flared to 90 Degrees

Letting the elbows flare perpendicular to the torso during the bench press creates maximum horizontal abduction at the shoulder joint, placing the pectoralis minor on a stretch that contributes to anterior shoulder impingement. The shoulder capsule experiences high stress in this position, which over thousands of repetitions creates the chronic shoulder pain that sends bench pressers to physiotherapy. The correct elbow position is 45 to 75 degrees from the torso, not 90 degrees. This position reduces shoulder joint stress, increases pectoral stretch at the bottom, and allows greater force production through a more mechanically advantageous pushing angle. Fix: consciously tuck the elbows toward the hips as the bar descends, aiming for an angle that feels like you are trying to break the bar apart laterally while simultaneously driving the elbows toward your feet.

Mistake 3: No Leg Drive

Most athletes think of the bench press as a pure upper body exercise and leave their legs passive on the floor. This ignores one of the primary force transmission pathways of the bench press: leg drive creates full-body tension through the posterior chain, transfers force through the hips into the bench, and stabilises the torso against the pressing force. Competitive powerlifters and strength athletes use aggressive leg drive to add 10 to 20 percent to their bench press maximum. Even for general training, active leg drive creates the stable base that allows maximum upper body force production. Fix: plant the feet firmly on the floor or on plates (depending on height), drive the feet hard into the ground throughout the press as if trying to leg press the floor away, and feel the resulting tension through the entire body.

Mistake 4: Flat Back on the Bench

Lying completely flat with the entire spine pressed into the bench removes the natural thoracic arch that is biomechanically advantageous for bench pressing. A moderate thoracic arch (upper back arched, creating a natural spinal curve) reduces the range of motion to the chest, positions the shoulder blades in retraction and depression that protects the shoulder joint, and creates a more stable pressing platform. This is distinct from an extreme lumbar arch used in competition powerlifting, which is a different technique with different considerations. A natural, moderate arch with retracted and depressed scapulae is the standard for all bench pressers who want shoulder health alongside performance. Fix: set up on the bench by first arching the upper back moderately, then pulling the shoulder blades together and down before unracking the bar.

Mistake 5: Wrist Hyperextension Under the Bar

Holding the bar with the wrists cocked backward (hyperextended) places the bar over the wrist joint rather than directly over the forearm bones. This creates wrist pain under heavy loads and reduces force transmission efficiency because the forearm cannot transfer force linearly from elbow to hand. The bar should sit in the palm at the heel of the hand with the wrists stacked directly over the elbows, keeping a straight line from elbow through wrist to bar. Wrist wraps are the most effective tool for maintaining wrist position under heavy loads, providing external support that prevents hyperextension during maximal pressing. Fix: before each heavy set, actively set the wrist position with the bar over the base of the palm and use wrist wraps to maintain this position throughout the set.

Mistakes 6 Through 9: Four More Costly Errors

Mistake 6: Bouncing the bar off the chest. Using momentum from the sternum to initiate the press reduces the pectoral loading at the most important point of the lift (the bottom stretch position), trains the bounce rather than the muscle, and creates bruising and potential rib stress with heavy loads. Fix: lower the bar under control and pause or at least touch-and-go with controlled contact before pressing.

Mistake 7: Uneven grip width. Using the same grip width for all bench press work without adjusting for individual shoulder width produces either excessive shoulder stress (too wide) or reduced pectoral activation (too narrow). The optimal grip width places the forearms vertical at the bottom position. Checking forearm angle at the bottom of the press and adjusting grip to achieve vertical forearms optimises both safety and force production. Our complete bench press guide covers grip width selection in detail.

Mistake 8: Losing upper back tightness mid-set. Setting the scapulae before the first rep then losing this retraction and depression as the set progresses leaves the shoulder joint progressively less supported as fatigue accumulates. The scapular position must be actively maintained throughout every rep of every set, not just at the start. Fix: cue actively squeezing the shoulder blades together and down at the start of each rep, not just the first.

Mistake 9: Pressing without a spotter or safety equipment. The bench press is one of the most dangerous exercises when performed without a spotter or safeties because a failed rep with the bar over the chest can cause serious injury. Always use a power rack with the safeties set at chest height, a spotter for near-maximum attempts, or a bench blaster sling that provides sticking point assistance. The bench press safety guide is in our bench press safety guide.

Frequently Asked Questions

Why Does My Shoulder Hurt During the Bench Press?

Shoulder pain during the bench press almost always traces to one or more of the technique errors described above: elbows flared too wide, bar path too high, no scapular retraction and depression, or wrist hyperextension that shifts load onto the anterior shoulder capsule. Video your bench press from the side and the front to identify which of these errors is present. Addressing the technique error typically resolves the pain within weeks, but any shoulder pain that is sharp, refers down the arm, or persists at rest warrants physiotherapy evaluation.

How Do You Fix Multiple Bench Press Errors Simultaneously?

Attempting to correct multiple technique errors at once usually results in fixing none of them well. The systematic approach: reduce load to 60 to 70 percent of maximum and focus on one technical cue per session for 2 to 3 sessions, then add the next cue. The priority order is: scapular setup first (most impact on shoulder health), then bar path, then elbow angle, then leg drive, then wrist position. Each correction builds on the previous ones, so the order matters.
