An exercise device (1), for example a dumbbell or barbell, for weightlifting and other fitness activities comprises a lifting bar (2) having an axis (3) and opposed axial ends, and a pair of weight sections (4) mounted spaced apart on the respective opposed axial ends of the lifting bar (2). The lifting bar (2) extends between the spaced apart weight sections (2) defining a handle (5). Each weight section (4) has an outer circumferential surface (8), an inner axial end face and an outer axial end face (10). The circumferential surface (8) of at least one of the weight sections (4) comprises a plurality of grooves (12; 12a,12b,12c), preferably arranged in set (13,14) on diametrically opposed sides of the weight section (4), each extending generally circumferentially around only part of the outer circumferential surface of the weight section (4) and spaced substantially axially from an adjacent groove (12; 12a,12b,12c) axially along the outer circumferential surface of the weight section (4). The sets (13,14) of grooves define grip areas on the weight section (4) with there preferably also being recess portion (18,22) formed in the axial end faces (10,11), to enable a user to better grip and lift the dumbbell (1) by the weight sections (4). The outer circumferential surface (8) is also preferably of a barrelled shape to match and fit in the palm of a users hand. |
