Why the payment will be like and what is the benefit out of it? How many days can someone do exercises and how long it will be take?

With the black card membership you can use any club, anywhere. It is a bargain. The gyms are very clean. The payment is deducted from your account automatically every month.

I have the black card and i use it anytime my schedule permits and at any facility in any state

$1 down $10 a month basic membership. $1 down $21.99 for black card membership. Open 24 hours 360 days a year. They will charge a annual $40 fee.

You should visit a local Planet Fitness personally and ask those questions. The staff is very friendly and patient and will answer any questions. Payment plans vary depending on the level of use of the facilities that you want.
