Don’t be shy.
Introduce yourself to your instructor and to other participants. Your instructor will be pleased to meet you and to get to know you and participants are usually very friendly. You may make new friends or find a workout buddy.
Come up to the front row, you can see better and there’s no one blocking you. Answer when asked a question during class and don’t be afraid to express yourself when having fun or pushing your limits. Your instructor appreciates responses and likes to see and hear how you are feeling and doing. So go ahead and Woohoo! You know you want to.
