I bought 30 Day Shred ( by Jillian who is one of the trainers on The Biggest Loser ) and I did level one this morning , and it made me sweat my butt off ! I highly recommend this to everyone . It is a twenty minute program , which is perfect for my busy schedule . She follows the 3 - 2 - 1 approach which is 3 minutes strength , 2 minutes cardio and 1 minute ab work .

Question: Why did I recommend it ?
