She is SUPER famous from the TV show 'The Biggest Loser' and I have always liked her way of training people. She is the kind of a person who will push you to your limit and will do it the way that you will want to do it! You will want to please HER.
She released these DVD series of "30 day"-workouts.
One of the workouts in the series is 30 day shred.
It does not promise anything, but boy... Just google the results!
She will make you work! 20 minutes a-day, 10 days for level 1, 10 days for level 2 and 10 days for level 3 and you're done!
I recommend you ordering your DVD's online, for example Amazon, but to be honest, these things are found online for free. So if you can afford it - buy it! Support the work she is doing! (or if you feel that she doesn't need the extra money, just donate it to something). If you're poor as hell... Like me ;)
Here are the youtube videos, but you will need to scroll down first, get inspired by these Before And After pictures. WORK FOR IT!!! (but if you've already seen these pic's, here are direct links: Level 1, Level 2, Level 3)
NOTE!!! These are all results from the 30 Day Shred program. I will be later on introducing you the other 30 day workouts by Jillian!
And here are the videos!
