What you’re working: Obliques, hip flexors and other muscles are engaged to maintain stabilization as you move through this exercise.
How to do it: Starting from plank position like you are going to do a pushup, walk your feet towards your hands in baby steps.
Once you get to the point when you have to start bending your legs, start walking your hands forward in baby steps until you are back in the plank position. Repeat for one minute. Tip: Go nice and slow. Controlled movements will keep your core engaged throughout and you’ll get a better burn. Also, keep your head in alignment with your back.
