The SportsArt DF-304 pairs pec fly and rear deltoid fly in a single Performance Series machine — training opposing upper body muscle groups that are rarely exercised together. A single ergonomic handle works for both movements, multiple starting adjustment points accommodate every body type, and a 5.5 lb starting weight makes it one of the most accessible machines in the entire DF series.

The DF-304 pairs pec fly for chest isolation and rear deltoid fly for posterior shoulder development — two opposing arc movements that create balanced pushing and pulling strength across the shoulder complex. Training them together on one station addresses one of the most common muscular imbalances in regular gym users: overdeveloped pecs relative to weak rear delts.
A single ergonomic handle is designed to feel natural and comfortable for both the pec fly arc and the reverse rear deltoid arc — eliminating the need to swap attachments between exercises. The handle geometry keeps the wrist in a neutral position through both movements, reducing joint stress and allowing users to focus fully on the target muscle.
Multiple starting position adjustment points allow users to set the arm pad start angle for both pec fly and rear delt fly to match their shoulder width and range of motion. Combined with the adjustable seat, the DF-304 fits users of different heights, arm lengths, and flexibility levels — ensuring every rep begins from a safe, mechanically correct position.
At 5.5 lb, the DF-304 has the lowest starting weight in the entire Performance Series Dual Function lineup — making it ideal for rehabilitation patients, post-surgical shoulder recovery, seniors, and anyone building foundational chest and shoulder strength from scratch. The 220 lb stack ensures it scales all the way to advanced training resistance as users progress.
At 409 lb with a 500 lb user capacity, the DF-304 delivers the structural integrity the Performance Series demands in a relatively compact 51.2" × 46.9" footprint. The mixed 11 lb and 16.5 lb plate stack provides useful progressive loading options across the full range from light rehabilitation work to maximum-effort chest and shoulder isolation.
