I've tried out many gyms, mostly downtown, and I really believe that LPAC up in linclon park is the best gym in Chicago. The equipment, locker rooms and ambience at most higher-end gyms in Chicago are all quite good, so what really makes LPAC stand out to me are their personal trainers. They do an excellent job of selecting the staff at this club, they are very intelligent, friendly and dedicated to helping you out. Every trainer is certified to work with you on all of the equipment at the gym, and they cover many different specialties. You can easily hire a trainer for a single session to answer questions you have and teach you specific things, so it's entirely up to you whether you want a whole package of sessions or just one. They have trainers focused on triathlon and marathon training, and I've found them to be extremely knowledgeable and unbelievably helpful when I go over my training plans with them. Even with my enthusiasm for it, I really don't think I would be doing triathlons if it weren't for the help they've given me, and it's been so much fun. They also have many pre-natal classes, which I haven't seen elsewhere, and a good swim training class, and I've heard their yoga classes are excellent but I haven't tried them yet. I'm just really happy with this gym!
