If you don't have a lot of time and you want to ignite your abs, a quick, high-intensity workout is exactly what you need. This ab workout is going to work your obliques, your rectus abdominals (the six-pack muscles), and your transverse abdomnis (your deep core muscles); you're going to be winded once it's over. Grab a towel and some water, because it's about to get sweaty!
