You'll have to contact a Megatlon directly to inquire about their monthly rates. Their rates go up periodically. I can tell you that it is much more costly to pay month-to-month than to do six or more. Depending on what your needs are you might want to look into a cheaper neighborhood gym (my boyfriend just lifts weights and runs on a treadmill and pays $80 pesos a month--I go to classes at the Megatlon and got a good deal when I paid a year in advance at 25% discount which brought the price down to around $125 a month.
