1. SPIDERMAN PLANK
Start in a classic plank position with your forearms on the ground and your body completely in a straight line. Bring your right knee ahead towards your right elbow, then get back to the plank position. Repeat by bringing your left knee toward your left elbow. That’s one rep. Alternate sides for a total of 10 complete reps.
“The plank is pretty much one of the only exercises where you’re getting your entire core. You’re working the front and back of your abdominal area at the same moment without any equipment. You’re getting your rectus abdominis, your obliques, and your lower back. It’s so easy and effective that you can do it anywhere.”
