If you tend to shy away from crunches (and you probably should), we've got your new go-to move. The Pilates Teaser combines abdominal strength, core strength, balance, and coordination to sculpt your tummy into shape in no time. Perform each of these 3 variations in a row (or just do the ones that feel best for your body) 8 to 10 times each, and 4 to 5 times a week for the best results. (Get long and lean with sexy Flat Belly Yoga!)

Teaser 1 (Beginner)

Lie on back with knees bent, feet flat on ground. Extend arms back behind you overhead. Tuck chin toward chest, and roll up to sitting. Sit up as tall as you can on sit bones, and use core to hold and balance at top. Keep core pulled in and return to starting position by rolling back down with control and resistance. The slower you go, the more your core will work. If you need some extra assistance, use your hands to help you by "walking" them up your legs.

Lie on back with legs in tabletop position. Extend arms up to sky. Tuck chin toward chest, and start to articulate and roll up to sitting. Keep inner thighs squeezing together the whole time. Keep core pulled in and return to starting position by rolling back down with control and resistance. Keep shoulders down back and away from ears. Again, the slower you go, the more your core will work. If you need some extra assistance, use your hands to help you by "walking" them up your legs.

Lie on back with legs extended out long in front. Extend arms back behind you and overhead. Lift arms up toward toes, while simultaneously using core to lift body and legs. Continue rolling upward until legs and upper body are in V-shape position. Sit up tall, balance, and hold. Return to starting position by rolling backward, keeping core engaged, and making sure not to rely on momentum.
