Benches are manufactured by many different vendors, in an array of qualities, features, and prices.
In recent years, many home fitness enthusiasts have begun incorporating a swiss ball into their workouts in place of a traditional bench, since it is both more space-efficient and requires engagement of the core abdominal muscles.
This substitution is not without criticism, since it can be difficult to maintain form and balance when lifting more than one's own body weight.
It is a bench that is specifically made for performing ab exercises.
These benches have foot rollers that are used to lock the feet thus protecting the exerciser.
