How about strong enough? What's strong enough that is going to put you in pretty much the top 5 percent of your cohort? Most people I've seen who have the look of a weight trained athlete are pretty decently strong. You can't wear strength. What do you want to be some crypto hidden strong guy that looks like shit but can impress everyone during that 1 in 10,000 moment when something really heavy needs lifting? I'll pass on the whole Sri Chinmoy deal.
Frankly the whole strength thing goes back to the Riddle of Steel anyway. Your mind is what will determine your strength through determination, will power, effort, etc.
