Take about 4 “steps” forward with your hands, keeping your core tight to avoid rocking back and forth, add a push up when you get to your full plank, and then walk your hands back to start. For an added push (pun intended), add an additional push up each time you get to it!Lunge JumpsStart in a standard lunge, ensuring your front knee is not coming over your toe. Bring your weight straight up and down, rather than forwards or backwards. As you jump, switch the position of your legs.Side LungesTake a wide step out to the left. Bend your left knee as you push your hips back. Keep both feet flat on the floor throughout the exercise. Push off with your left leg to return to standing, and then repeat on the other side.Side plank with a CrunchPick a side, any side! Beginning in a side plank, keep your core tight and waist lifted. Bring your top leg up toward your shoulder to lightly tap your elbow, lengthen your leg back to that side plank. Switch sides each round!
