gym80 Pure Kraft Butterfly 50°

The Butterfly 50° isolates the lower chest by loading heaviest in the stretched position and easing off toward the end of the rep — the opposite resistance curve from a standard pec deck, and the reason it’s specified alongside one rather than instead of it.

• Focus on the lower chest muscles
• Higher resistance in the stretched position, decreasing toward the end
• Compensates for different arm lengths
