Hard CORE: Side Step Push-ups + Plank Jacks

Target your arms, chest, hips and core all while getting your heart rate up with this movement! If you're comfortable with push-ups, you beast, take your hands to the floor instead of keeping them elevated like you see in the video.

Perform this movement until you've completed 10-20 push-ups for 3-4 sets. Rest for less than a minute between sets. Pictured in the video is the modified (easier) way to do this exercise. If push-ups are super challenging for you, having your hands elevated like I do here will make this exercise possible for you.
