An exercise device 10 includes a weight bar 20, an arm support 40, a handle 45, and an armband connector 100. The weight bar 20 has a distal weight end 25 and a proximal support end 30. The arm support 40 is disposed at the support end 30 and has a fixing portion 43. The handle 45 is adjacent to the arm support 40. The armband connector 100 is adapted to securely attach to the arm 4 of a user 3 connected to the exercise device 10. The arm support 40 has sufficient longitudinal dimensions to provide support to the user 3's forearm 4 and adjacent wrist 7, limiting angular movement between them. The fixing portion 43 is provided for connection to the armband connector 100. The handle 45 is provided for gripping by the user 3's fingers 5 and thumb 6. The exercise device 10 is suitable for training and enhancing and / or improving overall strength, particularly upper body strength. This device 10 is particularly suitable for multidisciplinary and compound training.
