Today is the final part to our four-week fitness video series. How have you been going with it all? Feeling fit, strong and bikini-ready?

In our last workout together, we’re going to do a series of core-strengthening moves using an exercise ball. If you don’t have one, you can simply grab yourself one from your local Rebel, or online at

Why does this workout kick serious butt?

This workout combines the benefits of core control with the calorie-blasting effect of a good interval session. The result? A sexy set of abs, truly worthy of showing off not only on Bondi, but on the beaches of Thailand, Bali, Fiji, the Maldives. Actually, you better think about booking a holiday (or two) to show off your BUF abs, beauties!

What you’ll need...

You, an exercise ball, maybe a mat. That’s it!

The bikini body workout

You’ll have four separate sets to work through. In each set, you’ll have an exercise ball exercise and a cardio exercise assigned. In each of the sets, you’ll do one full minute of the intense cardio, then 10 repetitions of an exercise ball movement. Then, go back to the same cardio interval and repeat the ball movement for eight repetitions. After one final cardio hit and a short round of just six repetitions of the same ball movement, you’ll take a breather and move on to the next set, where you’ll get a new core move and cardio exercise and will repeat the same process, working down from 10.
