Make your planks more challenging for a great workout.
The simple plank is a great exercise that can build serious core strength. However, if you have mastered the plank and are reaching 2 or more minutes with relative ease, it’s time to start challenging yourself with a plank variation.
Try including the starfish plank for an extra challenge and to mix things up in your workout. You’ll start breaking through any fitness plateau you might have hit using just the plank.
