Since 2014

The Annex

The Annex is a private gym located inside The Sports Academy in Glen Carbon, IL. We offer functional fitness classes, boot camp classes, sports performance classes, personal training, and pregnancy and postpartum training.

When I think of a gym….sweating, people judging me, and quitting because it’s too hard. What I think of the Annex….family, supportive, laughs, and fabulous trainers who push me to be the best that I can be. I have never been discouraged or frustrated at class. All I know is I am stronger, more confident, and have to talk myself out of doing 2 a days!!
