I don’t personally buy into always being able to spot potential. You’re fairly lean and have visible muscle. Whether you’re serious enough to commit years to busting your ass in efforts to end up doing well onstage is the real question.
Many successful BBers don’t even touch weights until later on, simply because they don’t have the interest.
Based on your pics alone, I’m certain you have the drive to keep going. Don’t let the anonymous opinions from an online forum be the reasons though. Do it because you want to see how far you can go!
