Nick Kelley

Nick assists with coaching Cross-Training and Artis Barbell classes. He has been involved with fitness since 2012, with 3+ years of coaching experience. Nick's favorite part of being at Artis is the warmup, which he describes as "let's see how many random/current events topics we can talk about in the hopes that the hour finishes up before we actually have to exercise.” Likes: airports, sour patch kids, yard games, chapstick, the occasional pedicure, HBO Sunday night programming, pizza, golf, and I guess fitness. Dislike: the stretch of road between 51st and 49th and Underwood Ave in Dundee between 5 and 6 pm during the work week. It takes FOREVER.
