Basic Move: Side Plank
Lie on your right side with your legs straight. Prop yourself up with your right forearm so your body forms a diagonal line. Rest your left hand on your hip. Brace your abs and hold for 60 seconds. If you can't make it to 60 seconds, hold for 5 to 10 seconds and rest for 5; continue for 1 minute. Be sure your hips and knees stay off the floor.
Basic Move: Glute Bridge March
Lie on your back with your knees bent and your feet flat on the floor. Rest your arms on the floor, palms up, at shoulder level. Raise your hips so your body forms a straight line from your shoulders to your knees (A). Brace your abs and lift your right knee toward your chest (B). Hold for 2 counts, then lower your right foot. Repeat with the other leg. That's 1 rep. Do 2 or 3 sets of 5 to 10 reps.
Basic Move: Lunge with Rotation
Grab a 5- to 15-pound dumbbell with both hands. Stand with your feet hip-width apart and your arms straight out (A). Take a big step forward with your left foot and, bracing your abs, twist your torso to the left as you bend your knees and lower your body until both of your legs form 90-degree angles (B). Twist back to center, push off your left foot, and stand back up. Repeat on the other leg. That's 1 rep. Do 2 or 3 sets of 10 to 15 reps. Keep your elbows straight but not locked.
