Execution

Setup:

  • Adjust the seat height so that your elbows align with the padded armrests or handles.

  • Sit with your back firmly against the pad and keep your feet flat on the floor.

  • Position your arms with a slight bend at the elbows, keeping your forearms parallel to the floor.


Movement Phase (Concentric):

  • Exhale and squeeze your chest as you bring your arms together in front of you.

  • Maintain a slight bend in your elbows throughout the movement.
    Pause at the peak contraction for 1-2 seconds to fully engage the chest.


Returning Phase (Eccentric):

  • Slowly return to the starting position while controlling the weight.

  • Avoid overextending at the bottom to protect your shoulders.

Targets:

Men

  • Beginner: 40 lbs

Advanced Techniques:

  • Slow Eccentric: Lower the weight slowly (4-5 seconds) to increase muscle engagement.

  • Drop Sets: Reduce the weight immediately after failure and continue reps.

  • Partial Reps: Perform half reps at the end of the set to extend muscle fatigue.

  • Single-Arm Fly: Perform the movement one arm at a time to increase stabilization demands.

Focus On:

  • Keeping a slight bend in the elbows to reduce joint strain.

  • Engaging the chest fully and squeezing at peak contraction.

Key Tips:

  • Use a moderate weight to maintain strict form and prevent shoulder strain.

  • Keep shoulder blades retracted throughout the movement.

  • Focus on a full range of motion without overextending.

Common Mistakes:

  • Using too much weight, causing loss of control and reliance on momentum.

  • Overextending at the bottom, leading to excessive shoulder strain.

  • Not pausing at peak contraction, reducing chest activation.
