Best Fitness AB Mantis Bench (Black Finish)
A comfortable, seated ab bench that targets your upper and lower abs without getting on the floor - a 45o isolation seat, dual crunch and knee-raise functions, and it arrives fully assembled.
Make any time crunch time with the Best Fitness BFAB20B Semi-Recumbent Ab Crunch Bench. Ergonomically designed to tighten your midsection, strengthen your back and improve core stability, it puts you in a supported seated position so you can train your abs effectively and comfortably at home.
Why Choose the BFAB20B
- Isolates your abs: a 45o seat angle puts you in the ideal position to target the abdominals for a more efficient crunch.
- Dual function: ab crunches hit the upper abs and knee raises hit the lower abs - a complete ab workout from one machine.
- Adjustable for any user: two additional 5o reclining positions and a three-position upholstered seat suit every size and exercise.
- Comfortable and supported: upholstered upper-back support and textured grip handles - no acrobatics, no floor work.
- Add resistance: a standard weight post with spring lock lets you load it for a tougher crunch.
- Arrives fully assembled and backed by a 3-year warranty.
Product Description
The BFAB20B's 45-degree seat angle positions you to isolate the abdominal muscles for a more efficient workout, and two additional 5-degree reclining positions support an entire range of core exercises. Its dual functionality targets the lower abs with knee raises and the upper abs with crunches - a total ab workout from a comfortable seated position.
The ab-crunch motion uses upholstered upper-back support, textured grip handles and a standard weight post with spring lock (plus a lock-out option to help support knee raises). The knee-raise motion adds adjustable-length, 2-position foot rests and its own weight post. Unlike ab machines that require the agility of an acrobat, the BFAB20B keeps you comfortable and seated, and it arrives fully assembled.
Best Fitness - your home, your gym.
