Bench Press Flat Reverse Wide-Grip Smith

Start Position
End Position

Starting position:

  1. Lie face-up on a flat bench with feet flat on the floor on each side of the bench.
  2. Position the bench so that the bar is located above your chest when you are positioned under the bar.
  3. Ensure you have a five-point body contact with the bench. This includes the back of the head, the shoulder blades/upper back, glute region/lower back, and both feet.
  4. Grasp the bar with a supinated grip. Grip should be up to two times wider than shoulder width.
  5. Lift the bar off the latches by rotating the bar.
  6. Extend elbows (without locking elbows) and push bar upward.

Downward movement/eccentric phase:

  1. In a controlled fashion, allow the elbows to bend while lowering the bar towards your chest.
  2. As the bar is lowered, the upper arms should be close to your torso.
  3. Lower the bar until it reaches your chest.
  4. Maintain the wrists rigid and directly above the elbows throughout the entire movement.
  5. Maintain the five-point body contact throughout the entire movement.

Upward movement/concentric phase:

    1. Extend elbows, pushing the bar upward, returning the bar to starting position (do not lock elbows).
    2. When your set is complete re-rack the bar by rotating the bar to relatch the bar.
    3. Maintain a tense grip on the bar until it is relatched.
Do not lift feet off of the floor or arch back throughout the lift and descent. Do not bounce the bar off of the chest at the bottom of the movement when proceeding to the next repetition/concentric phase. Do not hold your breath. Exhale during the concentric/phase phase and inhale during the eccentric/lowering phase.

  • FAQ'S & FACTS ABOUT Bench Press Flat Reverse Wide-Grip Smith

    What Is A Smith Machine Reverse Wide-Grip Bench Press

    A wide reverse grip Smith machine bench press is a resistance exercise, which involves the primary horizontal shoulder adductor, the pectoralis major. It is a variation of the traditional bench press in which the wrists are rotated, switching to a supinated grip as opposed to overhand/pronated. This exercise is performed on a Smith machine.

    The concentric portion of the lift is shoulder flexion and elbow extension. The concentric portion involves the lifting of the weight. The eccentric portion is shoulder extension and elbow flexion, which involves the descent of the weight.

    The purpose of the wide reverse grip Smith machine bench press is to strengthen the upper portion of the pectoralis major while promoting hypertrophy (increases in size) of this muscle.

    Why Do A Smith Machine Reverse Wide-Grip Bench Press

    Wide reverse grip Smith machine bench presses increase the size and strength of the upper (clavicular) and lower (sternocostal) heads of the pectoralis major. The supinated and wide grip, however, significantly activate the upper (clavicular) heads.

    The wide grip provides greater activation of the upper pectoralis major fibers than with a standard width reverse grip. Therefore, the wide reverse grip Smith machine bench press is an effective exercise to develop the upper chest. The triceps brachii and anterior deltoid are also activated in this movement. The supinated grip also activates the biceps brachii.

    Performing wide reverse grip bench presses on a Smith machine minimizes the activation of stabilizing muscles (i.e. rotator cuff muscles) as the range of motion is controlled. This may allow the lifter to lift heavier weight compared to what they can lift with a free-weight barbell. The Smith machine latches also provide a level of safety and may allow a lifter to press without a spotter.

    The wide reverse grip Smith machine bench press serves as a valuable exercise to improve aesthetics of the pectoral muscle.

    Anatomy Of A Smith Machine Reverse Wide-Grip Bench Press

    The pectoralis major is a large, fan-shaped muscle that spans across the chest, forming the front portion of the axillary fold (arm pit). It is divided into two parts: clavicular and sternal. Its origin is located at the sternal end of the clavicle, the sternum, rib cartilage (ribs 1-6 [or 7]), and the aponeurosis of the external oblique. The fibers of the pectoralis major converge at the point of insertion located at the greater tubercle of the humerus. The pectoralis major aids in pushing movements as the shoulder adducts the arm against resistance. The supinated grip minimizes horizontal shoulder adduction on the concentric phase and replaces it with shoulder flexion and elbow extension to lift the bar. Shoulder flexion activates the upper fibers of the pectoralis major.1

    The triceps brachii is located on the back of the upper arm, originating at the shoulder and inserting in the elbow joint. It consists of three heads, the long, medial and lateral head. The medial head lies beneath the long and lateral head. The long head origin is located at the infraglenoid tubercle of the scapula (shoulder blade). The original of the lateral head is located at the posterior shaft of the humerus. The medial head origin is located at the radial groove of the posterior humeral shaft.

    The long and lateral heads make up the “horseshoe” portion of the triceps. All three heads merge, sharing insertion into the olecranon process of the ulna, located at the elbow joint.
    The triceps brachii extend the elbow joint.

    The deltoid is a thick, multipennate muscle that forms a curtain around the shoulder. It is the primary muscle involved with arm abduction and the anterior fibers are a primary shoulder flexor. The anterior deltoid is a primary synergist of the pectoralis. When developed, the deltoids give the shoulder their round shape. The origin of the deltoid is located at the insertion of the trapezius, lateral third of the clavicle and the acromion spine of the scapula. Its insertion is located at the deltoid tuberosity of the humerus.

    The biceps brachii consists of two heads, the long head and the short head. The biceps brachii assists with shoulder flexion as a weak shoulder flexor.

    The anconeus is a short, triangular muscle located at the elbow joint. Its origin is located at the lateral epicondyle of the humerus, inserting at the lateral aspect of the olecranon process of the ulna.

    The coracobrachialis is a synergist of the anterior deltoid and pectoralis major, assisting with shoulder flexion. It is a small muscle originating at the coracoid process of the scapula and inserting half way down the shaft of the humerus.

    The wrist flexors and extensors stabilize the wrists, the abdominals stabilize the torso and the rotator cuff muscles stabilize the shoulder girdle.

    How To Improve Your Smith Machine Reverse Wide-Grip Bench Press

    Wide reverse grip bench press on a Smith machine requires less activation of the shoulder’s stabilizing muscles, therefore, it is important to strategically alternate between free-weight versions of this exercise (i.e. barbell wide reverse grip bench press) and the Smith machine. Performing the free-weight variations of bench press activates these stabilizing muscles (i.e. rotator cuff muscles) and optimizes shoulder and chest strength performance.

    The confined tracks of the Smith machine may also place negative stress on the wrists with a wide and reverse grip, therefore, the barbell variation should be considered as a common alternative to the Smith machine.

    Focus on the concentric portion of the contraction, concentrating on “squeezing” as arms are fully extending as you push the bar upward.

    Emphasis on eccentric contractions, prolonging the eccentric portion of the contraction, may also be incorporated in a training program focused on increasing strength. This should be implemented accordingly and with adequate muscle recovery as eccentric contractions cause substantial damage to muscle tissue.

    In order to improve pushing performance through “sticking points”, partial repetition ranges may be implemented to improve full range of motion of the wide/reverse grip bench press. Strategically varying your grip width (narrow, standard and wide grip) and hand positioning (supinated grip, pronated grip) can improve overall bench press performance.

    It is important to note that your repetition and set volume will depend on your goals (e.g. strength, hypertrophy, muscular endurance). It is also important to allow adequate recovery days in between chest and triceps training to allow muscles to repair.

    Common Mistakes When Doing A Smith Machine Reverse Wide-Grip Bench Press

    It is very common to observe an individual arching their back in efforts of lifting the weight with more ease. This technique should only be performed by weightlifting professionals and can compromise the safety of lifters.

    Injuries Or Ailments & Their Effects Regarding A Smith Machine Reverse Wide-Grip Bench Press

    If proper technique is not adhered to (e.g. arching of the back, dropping the weight quickly instead of controlling the descent on the eccentric portion of the lift), the likelihood of injury increases.

    If proper technique and recovery are not adhered to, impingement syndrome, rotator cuff injuries, biceps tendonitis/biceps tendinosis, pectoralis major tears and glenoid labrum tears may result. It is best to avoid bench press exercises when addressing impingement syndrome/rotator cuff injury unless advised by a physical therapist.
