Machine Chest Press

Primary Muscles: Pectoralis Major (Sternal), Anterior Deltoid, Triceps Difficulty: Beginner/Intermediate

  • Step-by-Step Execution

    • Setup: Adjust seat so handles are aligned with mid-chest. Retract/depress shoulder blades into the pad.

    • The Movement: Drive the handles forward by bringing the elbows together. Avoid locking out the elbows completely to maintain constant tension.

    • The Finish: Slowly reverse the movement, ensuring the weight stack does not touch, and return to the deep stretch position.

  • Pro-Tips & Common Mistakes

    • Common Fault: Allowing shoulders to roll forward (protract) at the start of the press.

    • The Cue: "Keep your chest high and pin your shoulder blades to the seat throughout."

Machine Incline Chest Press

Primary Muscles: Pectoralis Major (Clavicular/Upper), Anterior Deltoid, Triceps Difficulty: Beginner/Intermediate

  • Step-by-Step Execution

    • Setup: Adjust seat so handles meet at the upper chest/clavicle.

    • The Movement: Press handles upward and slightly inward, focusing on the upper chest.

    • The Finish: Return to the starting position with a 3-second eccentric count.

  • Pro-Tips & Common Mistakes

    • Common Fault: Using too much front-delt by letting the seat be too high.

    • The Cue: "Drive your upper chest toward the ceiling."

Flat Dumbbell Bench Press

Primary Muscles: Pectoralis Major, Triceps Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Lie on the bench, feet firmly planted. Retract shoulder blades.

    • The Movement: Press both dumbbells simultaneously, maintaining a controlled path.

    • The Finish: Lower until a deep stretch is felt in the outer chest.

  • Pro-Tips & Common Mistakes

    • Common Fault: Allowing the dumbbells to "clank" at the top, losing tension.

    • The Cue: "Think about squeezing your pecs together, not just pushing the weight up."

Incline Dumbbell Bench Press

Primary Muscles: Pectoralis Major (Clavicular), Anterior Deltoid, Triceps Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Incline the bench. Position dumbbells at the top of the chest.

    • The Movement: Press upward, focusing on the upper sternum.

    • The Finish: Lower under control to the point of maximum stretch.

  • Pro-Tips & Common Mistakes

    • Common Fault: Using excessive arch in the lower back, turning it into a flat press.

    • The Cue: "Keep your spine neutral against the bench to isolate the upper chest."

Flat Barbell Bench Press

Primary Muscles: Pectoralis Major, Triceps Difficulty: Intermediate/Advanced

  • Step-by-Step Execution

    • Setup: Grip the bar wider than shoulder-width. Retract scapulae.

    • The Movement: Lower the bar to the lower chest/sternum, then explode upward.

    • The Finish: Lock out fully at the top.

  • Pro-Tips & Common Mistakes

    • Common Fault: "Bouncing" the bar off the chest.

    • The Cue: "Control the descent (2s), pause momentarily, then drive."

Incline Barbell Bench Press

Primary Muscles: Pectoralis Major (Clavicular), Anterior Deltoid, Triceps Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Bench at 30°–45°. Retract scapulae firmly against the bench.

    • The Movement: Lower the bar to the upper chest under control. Maintain a slight tuck of the elbows (approx 45 degrees).

    • The Finish: Drive the bar upward in a slight arc toward the eyes.

  • Pro-Tips & Common Mistakes

    • Common Fault: Over-arching the lower back to turn the movement into a flat press.

    • The Cue: "Push your upper back into the bench and keep your glutes down."

Assisted Machine Dips

Primary Muscles: Pectoralis Major (Lower), Anterior Deltoid, Triceps Difficulty: Beginner

  • Step-by-Step Execution

    • Setup: Position knees or feet on the assistance pad. Grasp parallel bars with a neutral grip.

    • The Movement: Lean the torso forward roughly 30 degrees. Lower the body until elbows reach 90 degrees.

    • The Finish: Drive through the palms to return to the starting position.

  • Pro-Tips & Common Mistakes

    • Common Fault: Allowing the shoulders to shrug toward the ears.

    • The Cue: "Keep your shoulders packed down away from your ears throughout the movement."

Assisted Dips (Resistance Band)

Primary Muscles: Pectoralis Major (Lower), Anterior Deltoid, Triceps Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Loop a strong resistance band over the handles. Step into the loop with one or both feet.

    • The Movement: Perform the dip with a 30-degree forward lean. The band will provide the most assistance at the bottom (where you are weakest).

    • The Finish: Control the ascent, fighting the band’s tendency to snap you upward.

  • Pro-Tips & Common Mistakes

    • Common Fault: Letting the band snap the body upward too quickly.

    • The Cue: "Resist the band on the way up; maintain tension in the chest."

Dips (Unassisted)

Primary Muscles: Pectoralis Major (Lower), Anterior Deltoid, Triceps Difficulty: Advanced

  • Step-by-Step Execution

    • Setup: Grasp parallel bars, lift bodyweight.

    • The Movement: Lean forward, then lower yourself until the chest is at the level of the bars.

    • The Finish: Drive back up until the elbows are near full extension.

  • Pro-Tips & Common Mistakes

    • Common Fault: Flaring elbows too wide, which causes internal shoulder rotation.

Weighted Dips

Primary Muscles: Pectoralis Major (Lower), Anterior Deltoid, Triceps Difficulty: Advanced

  • Step-by-Step Execution

    • Setup: Secure the dip belt around your waist. Grasp the parallel bars with a neutral grip and lift your body weight off the floor.

    • The Movement: Lean the torso forward roughly 30 degrees. Lower your body under control until the upper arms are at least parallel to the floor.

    • The Finish: Drive through the palms, focusing on squeezing the lower chest to return to the starting position.

  • Pro-Tips & Common Mistakes

    • Common Fault: Allowing the torso to remain upright, which shifts the emphasis primarily to the triceps rather than the chest.

    • The Cue: "Look down at the floor and keep your chest 'proud'—think about pushing your elbows into your sides as you press up."

Cable Flyes

Primary Muscles: Pectoralis Major Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Cables at shoulder or slightly above shoulder height.

    • The Movement: Bring hands together in front of the body with a slight, fixed bend in the elbows.

    • The Finish: Squeeze the pecs for 2 seconds at the center.

  • Pro-Tips & Common Mistakes

    • Common Fault: Turning it into a pressing movement by bending the elbows too much.

    • The Cue: "Hug a giant tree."

Incline Cable Flyes

Primary Muscles: Pectoralis Major (Clavicular/Upper), Anterior Deltoid Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Cables at the lowest setting. Stand in the center, grasping handles with palms facing forward.

    • The Movement: With a slight bend in the elbows, sweep the handles upward and inward until they meet in front of your upper chest/face level.

    • The Finish: Squeeze the upper chest at the peak of the arc, then lower with control.

  • Pro-Tips & Common Mistakes

    • Common Fault: Shrugging the traps during the upward movement.

    • The Cue: "Keep your shoulders depressed—pull from the chest, not the hands."

Flat Dumbbell Flyes

Primary Muscles: Pectoralis Major Difficulty: Intermediate

  • Step-by-Step Execution

    • Setup: Lie flat on the bench with dumbbells held above the chest, palms facing each other.

    • The Movement: Open the arms in a wide arc, maintaining the elbow angle until the dumbbells are level with your chest.

    • The Finish: Focus on drawing the biceps toward each other to bring the weights back to the start.

  • Pro-Tips & Common Mistakes

    • Common Fault: Lowering the weights too far, which puts excessive strain on the shoulder joint (bicep tendons).

    • The Cue: "Stop the arc when your upper arms are parallel to the floor."

Incline Dumbbell Flyes

Primary Muscles: Pectoralis Major (Clavicular), Anterior Deltoid Difficulty: Advanced

  • Step-by-Step Execution

    • Setup: Bench set to 30°. Hold dumbbells above the upper chest with a neutral, firm grip.

    • The Movement: Lower the weights in a controlled arc, feeling the stretch in the upper pectorals.

    • The Finish: Squeeze the upper chest to return to the starting position without allowing the dumbbells to touch.

  • Pro-Tips & Common Mistakes

    • Common Fault: Using weights that are too heavy, forcing the shoulders to rotate internally to compensate.

    • The Cue: "Control the eccentric; don't let the weight drop."

Straight-Arm Machine Flyes (Pec Deck)

Primary Muscles: Pectoralis Major (Sternal and Clavicular Heads) Difficulty: Beginner/Intermediate

  • Step-by-Step Execution

    • Setup: Adjust the seat height so that handles align with your mid-chest when arms are extended parallel to the ground.

    • The Movement: With a fixed, slight bend in the elbows, sweep the handles toward each other in a smooth arc.

    • The Finish: Squeeze the pectorals isometrically for 1–2 seconds when the hands meet in front of you. Reverse the arc slowly to return to the starting position.

  • Pro-Tips & Common Mistakes

    • Common Fault: Allowing the elbows to bend excessively, turning the exercise into a pressing movement.

    • The Cue: "Keep your elbows locked in a 'fixed' position; think of your arms as stiff levers."
