100's
Lie face up and bring legs up, keeping them straight and together.  Lift head and shoulders off the ground, pulling in the abs (don't let them bulge out) and bringing hands next to thighs.  Lower the legs as much as you can while keeping your back on the floor and press hands up and down, counting with each press.  Inhale for 5 counts, exhale for 5 counts and repeat until you hit 100, lowering your legs once again halfway through.  

Leg Circles
Lie face up on the floor and raise right leg straight up over hip, toe pointed.  Keeping abs tight and torso stabilized slowly circle leg clockwise 5 times, making big circles without moving your torso or hips (only the leg moves).  Repeat 5 times counterclockwise and switch legs.  Repeat 2-3 times on each leg.

Tree Pose
Stand with feet planted, arms at sides and body in alignment (ears over shoulders, shoulders over hips, hips over ankles).  Inhale and bend the right leg, pulling the heel up until it rests on the inside of the left thigh.  Get your balance and hold this position, then slowly push arms overhead, palms touching each other.  Press the knee back without moving the hips.  Hold this for 30 seconds then switch sides. Repeat 2-3 times

Plank 
Lie face down on mat with elbows resting on floor next to chest.  Push your body off the floor in a pushup position with body resting on elbows or hands. Contract the abs and keep the body in a straight line from head to toes.  Hold for 30-60 seconds and repeat as many times as you can.  For beginners, do this move on your knees and gradually work your way up to balancing on your toes.

Side Hip Flexion and Extension
Lie on your right side with head supported on the right hand, legs straight and in front of you about 30 degrees.  Lift the left leg, flex the foot and press it forward for 3 counts, then point your toe and swing leg back for 2 counts.  Do not move any other part of your body (keep torso and hips tight and in place, moving only the leg).  Repeat 5-8 times and switch legs.
