Summer may be coming to an end but a killer core is never out of season. A strong core not only gives you a slim physique, but also reduces back pain, improves posture, increases balance and gives you a confidence boost. In order to build lean muscle and flatten out your stomach, your workouts need to challenge the core in many different ranges of motion. These dynamic moves will strengthen your abs to flatten things out and maintain a six-pack, strengthen your obliques to create a v-shape and work your hips to give you an hourglass figure. Perform the workout 3-4 times a week on its own or in addition to your usual workout. Once you get through each exercise, rest for 30 seconds and repeat the entire routine three times. You only need a mat, so you can complete this workout anywhere! To read more click here!
