Level 3 is 33 minutes long; 2:30 minute warm up and 1:30 minute stretch. Equipment needed: dumbbells from 3-8 pounds and a fitness mat. This workout is definitely the most advanced of the 3–very challenging. And no fun. Great workout, but it is 30 minutes of advanced core work with a few more fun and interesting moves thrown in to work your core in different ways–but mostly, lots of hard plank based moves. This is one of those Jillian workouts that, for me at least, it was impossible to go very heavy because the moves were so challenging.
