Bodyweight Flyes

What it is

This challenging isolation exercise dynamically works your chest muscles by rolling two E-Z curl bars apart and together. It effectively strengthens your pectorals, with significant secondary engagement from your core, shoulders, and triceps for stability.

Technique tips

• Maintain a rigid, straight body line throughout the movement.
• Control the E-Z curl bars smoothly and slowly.
• Inhale as you extend your arms outwards.
• Exhale as you pull the bars back to center.
• Engage your core to stabilize your torso.
• Only go as wide as you can control.

How to track your progress

Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
