ABSTRACT:
A training device (10) for exercising the abdominal muscles (40) of a user (30), comprises a base portion (11), an upstanding resistance member (21) contained within a housing (12) and a plunger (13). The resistance member (21) is operably connected to the plunger (13) and is biased normally to urge the plunger (13) upwardly out of the housing (12). By standing on the base portion (11) and exerting a downward force (c) on the plunger (13) whilst keeping his arms (41, 42) and legs (43, 44) straight, the user (30) causes his abdominal muscles (40) to work to overcome the resistance to the downward motion of the plunger (13) provided by the resistance member (21), thus driving the plunger (13) downwards into the housing (12).
