well you can hire a bus you and 36 other people who will like to WORK OUT WHILE ON THEIR WAY TO WORK ON THE PRIVATE BUS...Some buses drivers in some countries get paid: $500 a month....Even if they dont...$500 dollars divided by 36 passengers = $13 dollars a month you will pay...the bus takes, 2 hours to pick you up and the 36 passengers and get you to work everyday, that leaves him with: 6 hours daily for more passengers so thats another, $500 a month and if he only takes you 4 days of the week and the other 3 days of the week he services other people, that´s another: $500 a month with 6 hours left per day, those 6 hours are another, $500 a month...The Bus driver will make in total: $2,000 a month at least...Also think about it you cant work out everyday...So you will be working out in the bus 2 hours a day going and 2 hours coming for 4 days with 36 people...It will be your, PRIVATE GYM BUS, CHEAPER THAN A GYM MEMBERSHIP AND YOU WILL LOSE WEIGHT IN NO TIME ALL ON YOUR WAY TO WORK AND COMING FROM WORK...YOU WILL BE DOING IT FOR 30 YEARS EVERYDAY ON YOUR WAY TO WORK...THEORETICALLY YOU SHOULD BECOME FROM A FAT GUY/GIRL TO A MALE/FEMALE BODYBUILDER...BETTER THAN A GYM AND YOU WILL NOT BE ALONE...IT WILL ONLY COST YOU: $13 A MONTH...
