4Work on Your Abs
A flat stomach will definitely help you look and feel great in a bikini. One of the main functions of the abdominal muscles is to connect the upper body with the lower, with a key role in daily activities.
Therefore, the best exercise for iron abs is lifting your legs. The ideal position from which you can perform leg lifts is by standing on your back, holding your hands to something fix (like a chair) and lifting legs with knees bent until you touch your chest. Repeat 40 times.
Remember that this kind of exercises are meant for when you already got rid of the belly fat. So, you won’t achieve nothing if you don’t combine them with some cardio training.
