But what that ultrasound study shows is that about 20% of people don't have that tunnel to keep the nerve from moving. Almost none of them ever noticed it. The only time someone notices it is if they are doing repetitive heavy lifting either with weights like you, or as part of a job.
As mike53 suggests there are ways you can get around this by varying your workout exercise, or maybe wearing that arm band.
