An adjustable multi-purpose dumbbell bench is a versatile piece of fitness equipment that can be adjusted to various angles and positions to target different muscle groups during weightlifting exercises. It typically consists of a padded bench that can be inclined, declined, or set to a flat position, allowing for a wide range of exercises to be performed. The adjustable feature of the bench allows users to target specific muscle groups by adjusting the angle of the bench. For example, a flat position is ideal for exercises such as bench press and shoulder press, while an inclined position is suitable for exercises like incline dumbbell press and incline flyes. The declined position is useful for exercises like decline bench press and decline dumbbell flyes. The multi-purpose aspect of the bench means that it can be used for a variety of exercises, including chest exercises, shoulder exercises, back exercises, and arm exercises. Some benches also come with attachments or add-ons, such as leg curl or leg extension attachments, which further expand the range of exercises that can be performed.
