Machine Iso-Lateral Chest Press

The Iso-Lateral Chest Press (Machine) uses two independently moving plate-loaded arms for a supported horizontal press. Unlike a selectorized chest press with linked handles, each side can travel and be loaded independently.

Step by step

How to do the Machine Iso-Lateral Chest Press

  1. Adjust the seat so the handles align around mid-chest height and place the back and head firmly against the pads.
  2. Plant the feet, grip both independent handles, and begin with the elbows slightly behind the torso without overstretching the shoulders.
  3. Press both lever arms forward and slightly inward while keeping the shoulders down and the wrists stacked over the elbows.
  4. Stop just before the elbows lock, allowing each side to finish under control without twisting the torso.
  5. Return both handles slowly until the chest is comfortably stretched and the plates remain controlled.
