6 Exercises to Tone Your Lower Abs

Lie down on your back, place the infinity loop above your knees, keep your feet shoulder width apart, interlock your hands behind the ears, so that your neck is properly supported. Lift your head up, so that the tips of your shoulder blades are off the ground and you are looking at your navel. As you exhale bring one knee to the chest, and go back to the starting position as you inhale and continue the movement alternating the legs.
 

Bring both legs into tabletop position and stretch one leg out for your starting position. Keep stretching the alternate leg out, while you keep the head up and engage the core at all the time.
 

To add another dimension to the previous exercise, place the loops around the feet and flex the toes. 
 

This is a great way to tone your arms as well as your lower abs. Get on your hands and knees. Slightly round the back and bring the opposite knee across to the opposite wrist. 
 

Interlock the hands behind the head and move side to side to elongate the neck. Bring the soles of your feet together so that the knees are apart. From this position crunch, while exhaling up and inhale as you come back to the starting position.
 

Keep the soles of the feet together and the knees apart, stretch out your arms. As you exhale, engage the core and lift the upper body up, come back to the starting position as you inhale.
