Callivan is a brand of Jinhua Lotto Sporting Goods Company. Although the brand is relatively young, it was only founded in 2011, but it has already gone abroad and achieved good results in foreign markets.
 
In terms of abdominal wheel products, Calliven mainly promotes the single-hand wheel, which is a very difficult abdominal wheel. While the Calliven single-hand wheel is designed for enhanced balance and stability, it is only suitable for consumers with a good fitness foundation because it requires exercisers to have some muscle power control.
 
Calliven has three one-hand wheels, the most worthwhile of which is the FU-945, a versatile workout combo. In addition to a roller holder for each hand, there is also a slightly larger roller disc. The roller wheel is actually a kneeling pad that replaces the ordinary abdominal wheel, which allows the user to put his knees or calves on the roller wheel to exercise the muscles of the lower body. Compared with the simple use of ordinary abdominal wheels, the single-hand wheel bracket of FU-945 can also be used as a push-up bracket, making this multi-functional combination can not only exercise abdominal muscles, but also exercise arms, shoulders and other parts.
 
But after all, the FU-945 is a high-end workout equipment, which is more difficult, and the FL-911 is more recommended for novices. The FL-911 is a more common and versatile widened wheel that looks similar to the Perfect Fitness Ab Carver Pro, with black handles and a gray and purple roller. FL-911 also has intelligent braking and rebound functions, which is more cost-effective than Kaisu KA27, with a single price of 59 yuan, and 79-89 yuan with a push-up bracket.
