I go to fit lab in Nashua on Amherst. Really nice gym that has all kinds of classes, a basketball court(a little dated for a court), it’s a touch pricey at 45.00 a month but that includes 24/7 access via a door key phone app. They do offer personal training sessions and there’s plenty of helpful people around to ask questions. Other benefits are a smoothie bar and a sauna(saunas close after staffed hours). The one thing I will warn you about is thier contracts. They are a little shifty in thier contractual shenanigans. When you’re signing up make sure you understand your contract terms especially if you sign up some personal training. Make it clear how many sessions you want, in what period of time and don’t let them pressure you into a long term contract, unless you want regular weekly training. Main point with them, read the fine print and don’t pay for what you don’t want. It’s an excellent gym/service otherwise.
