The HOIST® HD-3900 Pec Fly/Rear Delt machine is masterfully engineered for both versatility and precision. It boasts swiveling handles complemented by rotating grips, ensuring that users can effortlessly switch between various hand positions. This level of adaptability is further reinforced with the inclusion of multiple range-of-motion adjustments for both pec fly and rear delt exercises.

One of the standout features is the dual pivot system on each exercise arm. This design puts control squarely in the user's hands and allows for a truly customized workout experience. Tailoring doesn't stop there "“ the machine's seven seat pad adjustments mean that whether you're taller, shorter, or anywhere in between, a comfortable and effective exercise position awaits.

But it's not just about adaptability; it's about power. With a weight stack tipping the scales at a hefty 310 lbs (141 kg), users from novice to pro can challenge themselves adequately. The HOIST® HD Dual Series, especially with its signature Silent Steel® Weight Racks, has rightly earned its position as the equipment of choice in top-tier gyms, luxury hotel fitness centers, and renowned universities globally.
