Butterfly

About This Exercise

The Butterfly, or Pec Deck, is a focused strength exercise that isolates your chest muscles. By minimizing stabilizer involvement, it allows you to concentrate on building chest definition and mastering the mind-muscle connection, making it a powerful tool for sculpting your upper body.

1Setup

1. Adjust the seat height so the handles are level with your mid-chest. 2. Sit firmly with your back flat against the pad. 3. Place your feet flat on the floor for stability. 4. Grip the handles with a neutral or palms-facing-each-other grip, ensuring your upper arms and elbows are flush against the pads. Your elbows should be slightly bent.

2Execution

From the starting position with your chest stretched, slowly push the handles together in a controlled arc. Focus on squeezing your pectoral muscles throughout the movement. Exhale as you push. Hold the contracted position for a second when the handles meet in front of you, maintaining a slight bend in the elbows. Inhale as you slowly return the handles along the same path, stopping just before the weight stack rests, to keep tension on the chest. Avoid bouncing or using momentum.

Pro Tips

• Initiate every rep by consciously squeezing your chest muscles together.
• Keep your shoulders pinned down and back against the pad to protect your joints and maximize chest engagement.
• Focus on bringing your elbows together in the contracted position for a powerful peak squeeze.
• Maintain a smooth, controlled tempo, especially during the return phase, to keep tension on the target muscles.
