Do you belong to a gym?
I pay for my gym membership by the year, and it it $900.
Yes, for me, convenience and awesome classes/instructors are a must.
I belong to 2 gyms. One is free because I work there. The other prices everyone different so I did some negotiating and got it down to $29 inititation and $10 a month. Paying the initation grandfathered me in so my rate will never increase. Daycare is free at my free gym and the other is $2 for a first child and $1 for each additional child. There is a monthly rate available for that too but I don't go when I have my kids with me often enough to make it worth it.
The most I ever paid was $99 initiation and $49 a month.
