One of the most overlooked aspects of working out from a wheelchair is the problem of actually loading free weight onto the bar. This can be a mini workout in itself and if you are not careful, can be more likely to cause injury than actually lifting!
Below is a video of me loading a 45lb plate onto the bar for some heavy incline bench presses.
There are a few things to keep in mind when loading a barbell.
If going with heavy plates, 45lb, 35lb, or 25lb. (whatever is heavy for YOU) Do not set the bar above shoulder width.
Exercises such as Overhead Press or Military Presses will have the bar at a starting point that is higher, use a lighter plate. In my case I load 45s with the bar at shoulder height, but use 35s and 25s when the bar is above my eye level.
Pull the weight from the floor to your lap, reset, then lift the plate up and thread the needle as you see in the video.
If possible, use plates with handle cutouts like you see in the video.
If you have the balance and a lower injury level use two hands. But if you have a higher injury like me, you will need to load with 1 arm.
