We know what you’re thinking, “Is it even possible to get results in that amount of time?” According to BJ Gaddour, CEO of StreamFit.com, it is! He shares this cutting-edge core complex move that not only works on your six-pack muscles, but strengthens your entire core as well:

1. Using a Swiss-ball, the trick is to do three consecutive core exercises for 30 seconds each, which adds up to total of 90 seconds.
2. After that, rest for 90 seconds to complete one round.
3. Repeat these motions until you’ve done a total of 2 to 4 rounds.
