Women have 3 major trouble spots: the tummy, bottom, and arms. You cannot spot reduce fat because you will lose it all over, but you can spot enhance by targeting the areas to build lean muscle. Here are some tips for you to sculpt a perfect bikini body:

Arms
Nobody loves having a jiggling arm. The perfect exercises that target the same muscle group is a tri-sets barbell skull crushers followed by triceps bench presses, then bench dips. Apart from that, you can also add some form of biceps curl, chest press, and shoulder press workout.

Butt
Alessandra Ambrosio's trainer, Leandro Carvalho, might have invented the Brazillian Butt Lift which sculpts the rear by hitting the gluteus maximus, medius, and minimus. Such training plan can be purchased via online but if you would like to build a better backside on your own, you can try these alternatives (apart from squat) such as cycling, donkey kicks, and fire hydrant exercises.

Abs
Tired of doing sit-ups every day? Spice up your core workout with pilates because pilates focus on better posture, improved flexibility, and core strength. Moreover, you can always do plank if you have no time. Try to increase the time you can hold the position, and spice things up with lift a leg, raise an arm, or do some side planks.
