This is a great way to kill two birds with one stone and get your cardio and ab work done in one workout. I’m really not a big fan of cardio, mainly because I suck at it. I much prefer strength training. However, I do wish to increase my aerobic endurance, so I still make sure I get some cardio in every week.
The core is the foundation for the rest of the body. It’s really important to establish a solid foundation. Everything stems from the core, but it’s an area that a lot of people overlook. Trying to strengthen other areas of the body without having a strong core can lead to injuries.
Set an interval time for 5 minutes warmup (brisk walking), followed by 8 rounds of 20 seconds work (sprinting as hard as we can) with 10 seconds rest (walking) and then ending with a 5 minute cool down walk. You can substitute other high intensity exercise for the sprints, such as jump rope, riding your bike, high knees, etc.
Then do the following ab circuit 3 times:
1 minute crunches
1 minute reverse crunches
30 seconds plank
30 seconds high plank bringing knee up to elbow and alternating left and right
Don’t be fooled by this ab workout, it looks harmless, but it’s pretty powerful & will make you want to die on the floor for about 5 minutes after you’re done so make sure you stretch, stretch, stretch – feels so good for those sore ab muscles!!
