This was published in Cosmopolitan June 2006 by Victoria Lucia. Why am I posting it three months later after publishing? The reason is I've tried it and it works. I'm not doing blah blah here. Everything I post on this blog comes with my pure intention of sharing and the benefits of my experience and effort.
Two-point alternate lunges
Lie on your stomach with your arms folded in front of you, chin resting on top of your hands. Bend your knees and cross your ankles behind you as shown in figure (a).
Squeeze your butt tightly as you lift your legs slightly off the ground as shown in figurre (b).
Hold for one second , then slowly return legs to the floor.
Max the move: On the last rep of each set, suspend your legs as long as you can.
Stability Ball Squat
Stand with the ball between your midback and a wall as shown in figure (a).
Squeeze your butt the whole time, and keep your back straight, allowing the ball to roll dow n your spine. Keep hips facing squarely forward as shown in figure (b). Return to start.
Max the move: Don't rest between reps--keep up the pace.
Note: This can be done without the ball.
