For specific ways to target that tush, look no further. Trainer Daury Dross demonstrate moves he uses during the 50-minute Signature Fhix class at the Fhitting Room (1166 Lexington Ave., 212-772-1166, fhittingroom.com) to work those glutes:

1. Curtsy lungesSquat down so your knees are at 90 degrees (make sure they don't pass your big toe). Maintaining the squat position, cross your right leg behind your left leg by taking a lateral step. Return the right leg back to the original position. Working one side at a time, do as many reps as you can for 45 seconds on each side.2. Hip bridgesLay flat on your back with your arms by your side and your knees bent and shoulder-width apart. Raise your hips towards the ceiling while squeezing your booty until your back forms a straight line from your knees to your shoulders. Hold for 1 minute. Lower your hips so that your booty touches the floor. Complete 30 reps.3. Resistance

band step-outsPlace a resistance band around both ankles and start in a squat position. Drive the right foot out from the starting point, keeping your weight in your left leg. Do one side at a time for 45 seconds. Complete 15-20 reps.4. Kettlebell swingsStand with your feet hip-width apart, toes slightly out. Hold the kettlebell in front of you with both hands and thrust your body forward from the hips to swing the kettlebell to chest level. To bring the kettlebell back down, bend your knees slightly and send your booty back without squatting, then let momentum help take the kettlebell down between your legs/inner thighs. Do this for 45 seconds. Complete 15-20 reps.5. Lateral lungesStart with your feet together. Take a big step to the right with your toes facing forward and all the weight in your right leg. Bend your right leg while keeping your left leg straight. Keeping the right foot flat on the ground, push your hips back and push off your right foot. Continue to keep your left leg straight as you return to the standing position. Do one side at a time, for 45 seconds each. Complete 12-15 reps per leg.
