How this product scores for different use cases
Selectorized weight stack allows easy adjustments in small increments. The guided ab and back movements provide safe, controlled exercises ideal for beginners and rehabilitation.
The commercial-grade designation suggests durability for gym use. The 220 lb weight stack and dual ab/back functionality fill a specialized niche for commercial facilities.
The selectorized design with weight stack eliminates loose plates, saving space. However, without footprint specifications, space efficiency cannot be confirmed for apartment use.
This specialized ab and back machine lacks smith bar functionality entirely. Home gym enthusiasts need versatile equipment for compound lifts, which this single-purpose machine cannot provide.
This is a single-purpose machine for ab and back exercises only. It lacks smith bar, cable crossover, pull-up bar, and other essential stations for all-in-one functionality.
No smith bar, no safety arms, no J-cups, and no free weight capabilities make this unsuitable for powerlifting. The 220 lb weight stack is also insufficient for serious strength training.
Our Verdict
The Gronk Fitness Selectorized Dual Ab & Back is not a smith machine. It serves as a specialized core training station with a 220 lb weight stack. You get commercial-grade construction for ab and back exercises only.
The $3,499 price point positions this as a premium single-purpose machine. Most users need smith bars, cable systems, and free weight capabilities. This machine provides none of those essential features.
The 220 lb weight stack works well for beginners and intermediate users. Advanced lifters will outgrow this capacity quickly. The selectorized design offers convenience but limits maximum resistance.
Commercial gyms benefit most from this specialized equipment. Home gym owners should look for multi-station smith machines instead. You get better value from equipment that handles multiple exercise types.
The dual functionality trains abs and lower back muscles effectively. The guided paths help maintain proper form. However, the limited exercise variety cannot justify the high price for most buyers.
