Best Fitness AB Mantis Bench

In Stock

Make any time crunch time with the Best Fitness Semi-Recumbent Ab Crunch Bench. This ergonomically designed machine is built to help you tighten up your midsection, strengthen your back and improve your core stability.

The BFAB20's 45-degree seat angle puts you in position to isolate your abdominal muscles, for a more efficient workout. Plus, with two additional 5-degree reclining positions, you'll be ideally supported for an entire range of core exercises.

Its dual functionality lets you target your lower abs with knee raises and your upper abs with abdominal crunches. No other machine can provide such a total ab workout from a comfortable seated position.

The Best Fitness line of equipment takes much of the guesswork out of functional, effective home workouts with quality-built machines, ergonomically engineered equipment designs and a commitment to quality and customer satisfaction.

Unlike some other ab machines, which require the agility of an acrobat to be thoroughly effective, the AB20 Semi-Recumbent Ab Bench puts you in a comfortable, seated position to discover the many benefits of a regular midsection workout.

Never before has a single piece of equipment offered such an efficient combination of functionality and ease-of-use... anytime, anywhere in the comfort and convenience of your own home.

AB mantis bench

I’ve been using ab machine for several weeks now and I’m happy with my purchase. The leg raise moment isolates abdominal muscles very effectively and the crunch moment does a reasonable job too! I think it represents value for money as the machines I have used that are better all cost at least 5 times what the AB MANTIS did!
