How to Make Your Butt Look Good in a Bikini

The Kickback

We love this easy move. To do it, start out on all fours. For
 90 seconds, kick your right leg straight out behind you at 
a 45 degree angle to the floor. Do the same with your left 
leg. Repeat this three times.

Side-Walking Lunges

This exercise tightens up the outer part of your butt: 

Instead of lunging forward and backward, step out to the side, bend your right knee and lunge sideways. Repeat 10 times, and then switch to your left side.

Kettlebell Swings

Just like stair runs, kettlebell swings burn calories and tone 

your bod.

 Start with a light kettlebell in both hands, with your feet hip

 width apart.

 (Doing this at home? Use a milk jug with a screw cap—it

 works just like

 a kettlebell.) Swing the bell toward the back of your body 

and then thrust 

your hips and thighs forward while swinging your arms in

 front. Squat down 

when you bring it back toward the ground and repeat.

 Do this three times for

 30 or 45-second intervals.
