It was a long shot to begin with, so no one can be surprised by this.
Russell hit his target weight after months of training and eating right, but he has had trouble keeping it down since dropping a total of 51 pounds. Russell has always been a big body and often eclipsed 300 pounds, so this will be a constant battle for him.
In addition, Russell has also had issues with one of his knees. Russell has experienced swelling in the joint, and that has limited his ability to work out at full strength. It’s surely also a factor in the aforementioned weight gain.
Russell hasn’t given up, but at least for this year it doesn’t look like it is going to happen.
