Core training challenge every muscle in your body with full body exercises that burn more calories and fat. It's one of the best ways to get that lean toned look much faster. Get started with the moves below.

Static Lunge Dumbbell Curls
Holding two dumbbells at your sides, stand with feet hip width apart and take a big step forward with your left foot. Keep the heel of your back foot (right foot) off the ground, bend both knees slightly, pull your shoulders back, and contract your abs. Keep your arms and elbows aligned with your body, slowly lift the weights (don't swing the weights) until they almost touch your shoulders, and squeeze your biceps for 1 second. Make sure your arms and elbows remain aligned with your body and slowly lower the weights back down. Want to really challenge your body? Place your front foot on top of a dyna disc or your rear foot on a bosu ball or balance ball and see how much more difficult the exercise becomes. Perform 2 sets of 15-18 with a challenging weight. Tip: You can also perform dumbbell side raises, rear dumbbell flys and overhead dumbbell extensions in this position.

Decline Pushups or Dyna Disc Pushups
Get in a push-up stance with feet and lower legs (below the knees) on a balance ball or exercise bench and hands flat on the ground. If using dyna discs place both feet on discs and hands on the floor. Contract your abs and slowly bend your elbows so your forehead almost touches the ground. Push back up to starting. This exercise recruits major ab and back muscles so be sure you're contracting your abs and keeping your body as straight as possible to prevent injuries. Perform 2 sets of 8-10. Tip: If you're using a balance ball you can alternate between pushups and knee tucks to increase intensity.

Balance Ball Dumbbell Rows
Holding a dumbbell in your right hand place your left knee and left hand on a balance ball. Bend your right knee just enough so your body weight is mostly supported by the left side. Maintain a slight curve in your lower back and let the weight hang down next to the ball. Slowly row the weight back next to your ribs keeping your arm and elbow close to your body. Squeeze for one second and slowly lower back down. Perform 2 sets of 8-10 on each side. Tip: You can increase the intensity of this exercise by adding a tricep kickback just use a lighter weight and do more reps of rows (about 15) and less reps of kickbacks (about 10).

Single Leg Deadlift w/ Dumbbell Side Raises
Hold two light dumbbells at your sides, with shoulders back and abs contracted lift your right heel behind you to knee level forming a 90 degree angle. Balance on the left leg and slowly bend your left knee driving your right knee towards the ground until left leg is almost parallel with the floor. Raise back up to starting position lift dumbbells up and out to the sides squeeze and hold for one second then slowly lower back down. Perform 2 sets of 10 on each side. Tip: This exercise requires a lot of balance so you may want to rest the top of your right foot on a bench behind you.
