Plank walkouts, also known as the inchworm, is a bodyweight exercise well known for their core toning abilities. They also get fresh blood flowing into the upper body, chest, shoulders, and triceps.
Start from a neutral standing position, squeeze the core and bend at the waist folding forward until the hands meet with the toes on the ground. From there, walk the hands into a push-up position and slowly back to the starting position– this is one rep.
Beginners can modify this exercise by ending the walkout on the knees as if doing a modified push-up. However, add a weighted vest for 8 to 12 reps and 4 sets to intensify and build muscle.
