This 4-Minute Ab Circuit Workout Routine effectively removes “time” or “proper equipment” as an excuse to not squeeze in an ab workout today! This workout routine only takes four minutes to complete and does not require any additional equipment.

While I must admit that this 4-Minute Ab Circuit Workout Routine is not optimal in building your ab muscles and improving core strength, it is still pretty good if you put in a full effort.

Yes, there is a caveat to saving time − putting in MAXIMUM INTENSITY, which is the foundation of high-intensity interval training, also known as HIIT.

The point of this 4-Minute Ab Circuit Workout is to completely fatigue your ab muscles to stimulate growth, while burning a few calories in the process (which continue to burn after your workout if your intensity is high enough).

So how does this work? It’s simple. Follow the list of exercises to perform. You will perform each exercise for 20 seconds as fast and as hard as you can, with only 10 seconds of rest between exercises. You will complete 8 total sets for the full 4-Minute Ab Circuit Workout. If you have a few more minutes, I encourage you to do more to maximize the benefit.

Let’s get to it!
