I purchased this workout kit 6 weeks ago via Amazon.com at a very good bargain. I have been following this workout program for 4 weeks now and I really enjoy these short 20 minute workouts. I workout 3 days per week and feel like I get a full body workout each and every time. I have lost 6.5 pounds so far and I am pleased with my results so far. If you aren't use to working out to higher impact workouts like myself, follow the modified version of each workout. After time goes on I know I will be able to move on to the intermediate moves then advanced moves. The Firm Express Thin In 30 consist of four different cycles. There are a total of 13 workout dvds, one fitness guide and a 4 day flat belly kick start nutrition guide. Cycle 1: Ignite, is lead by master instructor Emily Welsh. There are 3 disc in this cycle which are: 1. Sculpt, 2. Cardio, 3. Cardio + Sculpt. Cycle 2: Accelerate, is lead by master instructor Rebekah Sturkie. There are 3 disc in this cycle which are the same as above. Cycle 3: TurboCharge, is lead by master instructor Alison Davis. There are 3 disc in this cycle which are the same as above. Cycle 4: Overdrive, is lead by master instructor Kelsie Daniels. There is 3 disc in this cycle which are the same as above. Bonus dvd: Kick Start Your Metabolism, is lead by master instructor Jennifer Ray. There are 2 workouts on this one dvd that are: 1. Pump It Up and 2. Shortcut To Flat Abs. I would recommend this workout system to anyone who is short on time and need a 20 minute workout that will give them a total body workout.
