Lie facedown on a mat, arms and legs extended to make a straight line. Place an object (such as a dumbbell or yoga block) on floor above head at armâ€™s length. Rest both hands to the left of the object so your body makes an arch to the left.
Contract your core muscles and lift your arms and legs up and over in an exaggerated arch to the right.
Slowly lower hands on the right side of the object. Let both hands and feet touch the ground momentarily, before making an arch to return to the left.
Continue lifting up and over your object until you have competed a set number of repetitions or a set time period. One arch in each direction is one repetition.
This low impact move is a great core exercise that not only strengthens and tones the lower back and obliques but also incorporates the shoulders, butt, and thighs. This is a challenging lower lumbar exercise that builds strength and burns many calories due to all of the large muscle groups involved. It is ideal for a home core workout and can be made harder simply by picking a taller object to move your arms over.
