First Zumba class here. First impression : grody disgusting door. Eewww. Arrived a few minutes early as a new student to check in. No one here. Once arrived, very friendly if a bit disorganized. Class did not start on time. Studio presents as tired and unclean. I didn't dare use the bathroom.
Disorganized was due to teacher called in sick. Understandable.
Several little ones present. So cool that they get to stay with their mamas. Not cool that the music is so loud that their developing ears will suffer.
Concrete floors combined with my bad feet, can't be a good outcome.
No instructions just loud music and you follow along. If all you want is an hour of movement and kind of dancing, it is that. All age ranges and ability levels and plenty of potential for injuries with no cautions about them.
Definitely a lot of movement.
