Well, if $28 will keep you going every month then go for it. I am not familiar with Alaska, but it is a little cheaper for a membership down here in California. This might be due to the fact that there are so many health clubs in competition here. My suggestion would be to even look into buying your own equipment to have at home. Its makes those "I was too lazy or too busy to drive to the gym today" excuses null and void

As far as the price you are quoted... does this force you into a certain location or certain days/times? There are many factors into how much they will charge you. Make sure to get all the info.
