I first put this disclaimer out there I do not own or represent "ignite" of nwi! The core workouts have been phenomenal. We are working out in cedar lake Indiana at ignite and we are the only one in there at 100.00 a month. These workouts don't look tremendously hard, but my daughter has been so sore! Lol in 4 months I'm sure I'll see big gains on the diamond! I have been so impressed I'm taking my wife next week to let her participate in the class!
