MAKE IT HARDER: PLANK ARM-LEG LIFT
This is the same move as before, except you’ll be in plank instead of tabletop! Start in plank position, hands directly under shoulders. Engage your abs and, keeping a flat back, lift your left leg up behind you and your right arm out in front of you. Continue to take deep inhales and exhales; work your way up to holding the position for 3 to 5 breaths. Pro tip: to make it easier, start with your feet slightly apart rather than together.
Works your: abs, butt, upper back
