Double Leg Lifts
Double Leg Lifts are a Pilates exercise that strongly works your core. By keeping your legs firmly together, you transfer most of the work toward your abs. This is more challenging than most Pilates exercises because you have to keep your legs straight. Most trainers call this the Mermaid exercise.
How To Do:
Lie face up on the mat and put your palms under your head with elbows wide open.
Spread the legs and raise them upwards keeping them joined at the heels and inhale.
Exhale as you pull your torso up from the floor and crunch your tummy, feel the tension in your back muscles and the abdomen at this point.
Hold this position for a few seconds and then slowly lower your torso in the mat.
Repeat this exercise 10 times at a stretch.
