Stability Ball Oblique Crunch
Three sets of 30 repetitions per side
The stability ball oblique crunch is a great exercise to build balance.
How to: For beginners, place your feet against the lower part of a wall. Lay sideways on a stability ball; make sure the ball is placed under your lower torso. You want to get a nice full-body stretch first and then come up and crunch until you feel that oblique. Release to the start position and repeat movement. Once you've completed 30 reps on the right side, switch to the left.
Once you're comfortable with this movement, move your feet away from the wall. This will require more stabilization work throughout your body.

Side to Side Rotational Twist
Three sets of 30 to 50 repetitions per side
This exercise is great to trim your obliques, improve balance, and work on coordination.
How to: In a seated position, bend your knees so your heels are touching the ground. Lean slightly back, but make sure your back is straight. Little to no weight is on your heels. Hold a medicine ball in your hands, start with 5 pounds and work your way up to a heavier weight. Use your core to balance and start to rotate side to side.
If the medicine ball is too challenging during the exercise, release the ball and clasp your hands. Keep doing the exercise until you complete the set.
For an added challenge, lift your feet off the ground.
Another option is to have your workout partner toss you the ball and do one side for 30 reps. Then repeat on the other side.
If for any reason you start to fatigue or lose form, take a small break. Build up to your muscular endurance. Once you're ready, continue where you left off. It's important to maintain proper form. Poor form can lead to injuries.
In addition, make sure to breathe in a rhythmic pattern, because if it is off, your form will suffer and you may get light headed.
