This type of exercise equipment facilitates a chest fly exercise using free weights instead of selectorized stacks. Users load weight plates directly onto the machine’s arms, offering a greater range of resistance and customization compared to other options. The design typically features two independent arms, allowing for unilateral work and accommodating various body types.
Free weight resistance provides a unique stimulus for muscle growth and strength development. It requires greater stabilization and control, engaging more supporting muscles than machines with fixed movement paths. This characteristic can lead to improved functional strength and overall athletic performance. Furthermore, the adjustable weight increments allow for progressive overload, a key principle for continued improvement. This equipment has evolved from simpler designs, reflecting advancements in exercise science and engineering.
