Lunge and Twist with G Ball

• This combination exercise helps to build your quads, glutes, shoulders and obliques. To start, stand upright and hold the ball in both hands out in front of you, keeping it just below chest level and your elbows unlocked. Stepping forward on one leg, lower yourself down and bend your knees to a 90-degree angle, keeping your thighs parallel to the floor. When you step forward, simultaneously turn your upper body and the ball toward the side of the leg you are leaning on. For example, if you are stepping forward with your right leg, turn your upper body to the right as you step forward, keeping your arms straight out and the ball in front of you. Then push back with your forward leg and return to starting position, straightening your upper body so you are facing forward again. Repeat this for two sets of 10 to 12 reps on each leg.
  
  

Squats with G Ball

• This exercise is great for your quads and glutes. Start with your feet about shoulder width apart and your toes pointed forward, holding the ball out in front of you slightly above your chest level. Keep your arms straight. Then, bending at the waist and pushing your weight back on your heels, lower yourself down while keeping your back as straight as possible. Make sure your knees don't bend past 90 degrees and that they don't come past your toes. Return to the upright position and repeat for up to 15 to 20 repetitions.
  
  

Clamshell Crunch with G Ball

• This exercise is good for an upper and lower ab workout. Start by sitting on a mat and placing the stability ball between your legs, holding it at your calves. Lie back into crunch position, keeping your feet just off the ground and your back flat on the floor. On your next inhalation, simultaneously lift your head and shoulders off the ground while lifting your knees to your chest. Exhale and return to starting position. Make sure your abs are doing the lifting and not the momentum of your knees swinging.
