Bikers have no choice but to lift weights and look intimidating because outside of prostitution and drug deals they have to extort money to live on, and the tougher looking they are, the easier people will pay up, where as some mob guys actually have brains and can think up good money making scams that the bikers never will...And has anybody ever seen a biker fight one on one with anybody ?? They fight five against one...Sonny Barger even admits that in his book !!
