Welcome to Day 3 of the 5 Day Challenge for Busy People! Today we're doing a brutal but fun blend of fat burning HIIT cardio and abs and core exercises (moves that target the abs, obliques and lower back). This is going to turn into a total sweatfest, and you're going to get in an awesome workout in under 30 minutes.

About This Workout:
We start off with a light cardio warm up; do not skip this part if you want to safely push yourself today and get the most benefit out of your workout. If you've been sedentary for a long period of time (i.e. watching tv or working at the computer for hours) before starting this workout, you may want to do a few extra minutes of a warm up. Once we're warmed up, we move into the core and cardio workout. We do the exercises in an AABB format; two rounds of a HIIT exercise (20 seconds on, 10 second off x 2) followed two intervals of a core exercise - repeat that sequence twice. A relaxing cool down and stretch is included at the end.

What if I'm still sore from the other 2 workouts?
By day three, if you've been pushing yourself hard, you just must be sore allover! If you are, don't worry, you don't necessarily have to take Day 3 off; we provide low impact and intermediate modifications all throughout this video, so you can always switch to the easier version shown in order to avoiding having to take a complete rest day. The second or third time you make your way through this challenge, you may find that you are able to do the harder version of the exercises shown, all the way through the challenge (at least more and more of the advanced version).
