Summer is just around the corner and it's time to get your beach body ready. Pilates is one of the most effective methods for toning the abs, hips, waist, and thighs. As Joseph Pilates himself allegedly said, in 10 sessions you'll feel better, in 20 sessions you'll look better, and after 30 sessions you'll have a completely new body.

Do these moves three to four times a week in addition to your other workouts and you'll be ready to rock that bikini with confidence.

The Hundred

Start lying on your back and lift your legs 45 degrees off the mat and lengthen out through your arms as you lift your head, neck, and shoulders off the floor. Pump your arms vigorously up and down five times on an inhalation and five times on an exhalation. Repeat 10 times for 100 pumps.

Single-Leg Circles

Start lying on your back and lift your right leg up and keep your body still as you make 8 clockwise circles, then 8 counter-clockwise. Repeat with your left leg.

Small Circles

Start lying on your side with your legs slightly in front of your hips. Lift your top leg a few inches, turn your toes up to the ceiling. Circle your leg forward 8 times then backwards 8 times, making tiny circles. Don’t let your body rock at all–stay solid in your center. Repeat on the left side.
