We’re your Group Outdoor Fitness Trainers in Melbourne I happen to run one of the best outdoor group fitness classes in Melbourne. Based in Princes Park in Carlton North - the Run It By Kate group fitness training is a fun - positive - and judgment-free environment to get fit! These group classes are a great way to connect with other people just like you and enjoy the great outdoors while working on your fitness.
