What You'll Get: This total body move takes the plank (a super-effective move for building core and upper body strength), and adds a dancer's plié to target the glutes, inner and outer thighs, hips and hamstrings.

Here's How: Place your feet against the wall, slightly turned out, and walk your hands out in front of you until you're in the standard plank position. For the plié, bend your knees and pull your hips back towards the wall. Push off the wall to extend back into your starting plank position. If you're really feeling ambitious, add a pushup when you're in plank position after each plié.

Do This Many: Do 2-3 sets of 15 plié planks, taking short rests in between.

When it comes to eating right, Kaiser -- who works with notoriously fit celebs like Shakira, Sarah Jessica Parker and Kelly Ripa -- emphasizes the importance of eating whole foods and drinking lots of water to promote long, lean muscles. "Stick to unprocessed foods without sugar and additives and preservatives," she says. "Whole grains, veggies and lean proteins are all going to help you."

Kaiser also recommends you cut yourself off from eating three hours before bed, and "stay away from sugar," she stresses. "It's more toxic than alcohol and four times more addictive than cocaine. Be wary of foods like skim milk, processed yogurt, workout recovery drinks and any type of bar," she says. These are some of the things we don't realize are high in sugar.
