text: AZ Training Lab is a great small format fitness studio I tried it with a GrouponLiving Social deal for one month of unlimited classes Classes start with a stretch then you go through a circuit of weights resistance andor cardio moves Sometimes the workouts are a good allaround mix and other times they focus on one particular muscle group like abs Great music and the class time goes by really quickly The ownersinstructors Ben and Dave are very positive and focused and take the time to chat with you call you by name etc They do a really effective job of helping you push yourself harder or modify as needed very motivational It seemed easier to push myself at each station during each circuit because we never spent more than a minute or so at each The setting is friendly not competitive or judgmental
