Winchester gyms

I'm looking to start going to the gym after work. Right now, I pretty much just want to do 12-3-30 and maybe a few other basic machines. I'm pretty much just hoping to jumpstart an exercise habit by going after work because once I get home I just can't make myself work out. Eventually, I may want to add in weight lifting but that's not really important to me at the moment.

Any feedback on local gyms? Planet Fitness is obviously the cheapest one and will have the basic equipment I'm looking for, which is a pro. Valley Health has a deal with my work but it's still much more pricey per month, though they have classes (only a few actually available around working hours) and I hear their amenities are very nice.

thanks for any thoughts!
