I absolutely loved the 90 minute workout!! It was my first time, but everyone was so nice and explained everything to me. Loved the treadmill sprints and the floor work. I get bored easily and this totally kept it fun and entertaining. 90 minutes flew by. I am disappointed they wouldn't give me a free trial, thats why I couldn't give 5 stars. I came in and they charged me $28!! That's more than I pay for a monthly gym membership :( But otherwise I loved it. Loved seeing my progress and learning how my heart rate is effected by my workout.
