With the holidays over and winter starting to settle in, a lot of your thoughts might to turning to summer and the beach weather it will bring. But your brain might also be sending thoughts about the weight we all inevitably gain--and how you're going to lose the unwanted poundage.There are a lot of different fad diets, crazy exercise machines, and ideas out on the internet about how to lose weight and get fit for the coming bikini season. One article will tell you not to eat a certain food, while another will say the exact opposite. Diet pills have all sorts of unknown side effects and unproven results. The best way to get rid of the weight you don't want? Exercise. I found a simple but effective routine to start you off with and I'll explain each of the ten exercises down below! 1. Single Leg DeadliftHOW TO: Grab a pair of dumbbells and stand on your left foot. Lift your right foot behind you and bend your knee so your right lower leg is parallel to the floor. Bend forward at your hips, and slowly lower your body as far as you can. Pause, then push your body back to the starting position. As you come up, think about using your glutes to push your hips forward instead of lifting from your back. Keep core engaged and chest up during the entire movement.WHAT IT DOES: Lifts and tones glutes and activates the entire core2. Side Plank HOW TO: Lie on your left side with your knees straight. Prop your upper body up on your left elbow and forearm. Raise your hips until your body forms a straight line from your ankles to your shoulders. Hold this position for 30 seconds. Turn around so that you're lying on your right side and repeat.WHAT IT DOES: Helps tighten and shrink waistline, works deep ab muscles that many exercises don't reach.3. Push UpHOW TO: Get down on all fours and place your hands on the floor so that they're slightly wider than and in line with your shoulders, feet close together. Lower your body until your chest nearly touches the floor and then push yourself back to the starting position.

Second Position PliesHOW TO: Stand with feet wider than shoulder-width apart, toes turned out slightly. Lower your body down by bending your knees until your thighs are parallel with the floor.
