I wouldn't stand a chance. Although 30 year old me from 10 years ago would get HIS ass wooped by 20 year old me from 10 years before that, but then 10 year old me would lose to 20 year old me from 10 years before that. Then 0 year old me wouldn't stand a chance against 10 year old me from 10 years before that.
Me from 10 years would have just gotten out of the military and was now competing in powerlifting and benching almost 460 pounds. Now I work an office job and have not worked out since the pandemic started.
