Side Plank. Lay on your right side, with your body in a straight line. Make sure your feet, butt, back and head are all in one straight line and your left foot is stacked on top of your right foot. Use your right forearm to push your body straight up so that only your right foot and right forearm are still on the ground. You should still be in a straight line, looking forward. Raise your left hand, fingers reaching toward the ceiling. Hold this position for as long as you can, trying to work your way up to 1 minute (or more!). When you’re able to tackle this, lift off your right forearm so you’re balanced on your hand with your arm straight underneath you (like in the picture). Switch sides and repeat.
Weighted Rope Climbers. In sit-up position, hold 2-3 pound weights in each hand and mimic climbing a rope between your knees. Keep your shoulder blades off the floor (or as close to off the floor as possible) as you alternate “climbing” your hands in front of one another.
Side Teaser: Lay on your right side, leaning on your right elbow (similarly to how you begin the Side Plank, above). Keeping your legs straight and “glued together,” lift both legs up together as you reach your left arm towards your toes and return slowly to the start position. Switch sides.
