"I should get one of those mouth guards so I can just bite down," Mealer said as he lay on his back.

Barwis helps Brock up, then leads him to a wall that is 66 yards away from the other wall and coaches him to do what was once deemed nearly impossible. When Brock takes a step with his right leg, his right arm goes from parallel to the ground to above his shoulders and same happens when he steps with his left leg and uses his left arm to maintain his balance.

Brock can walk so well his fiancee jokes that he's going to overshadow her moment when she walks down the aisle to marry him this December.

"I feel like I'll get to that point where standing won't be a problem and walking for the wedding in a way that doesn't look as scary as it does sometimes when I flap my arms out," he said after a workout on Sept. 21, his 28th birthday.

While Brock has done something he was told he couldn't do — a feat that leads to speaking engagements and strangers asking to take a picture with him — he has a long-term goal of ditching his wheelchair and simply blending in with the crowd.

"My ultimate goal is to be able to walk in somewhere and not have anyone notice anything different about me," he said softly.
