Commercial-style ab crunch & back extension in one station — ideal for HOME GYM OWNERS and COMMERCIAL GYM
Build a stronger, more resilient core with the Body-Solid Pro Dual Ab & Back (DABB-SF). Its crunch-style rotation path locks in proper mechanics for maximum abdominal contraction, while the counterbalanced resistance arm and gas-assisted seat let you dial in perfect alignment for ab crunches or back extensions. Oversized pads, smooth pulleys, and aircraft-grade cables deliver a quiet, consistent feel rep after rep — whether you’re training at home or outfitting a studio.
Crunch-Style Motion Path
Guided rotation emphasizes true abdominal flexion for deep contraction and results you can feel.
