The optimal caloric deficit when you are training 4 times a week is different than the optimal caloric deficit for merely losing weight. You must eat enough food to fuel your training and feed your muscles but still be in a state of a caloric deficit to keep burning fat.

The reverse crunch comes in 7th place for effective ab exercises, with a focus on the rectus abdominis. With this move, you're curling the hips off the floor, so you'll feel this in the lower part of the abs. The key to this move is to avoid swinging the legs to raise the hips. This is a small, subtle move, so you only need to lift your hips a few inches off the floor.
The crunch is the most popular abs exercise because anyone can do it. But that doesn't mean it's the best exercise for training your middle. "Crunches flex your trunk," says David Jack, owner of ActivPrayer in Phoenix, Arizona and creator of Men's Health MA40 Workout.

You may think of power bars as protein-loaded snacks that are perfect pre- or post-workout. And while you’re not entirely wrong, you’re not entirely wrong, either. In addition to high protein levels, many power bars are surreptitiously loaded with sugar, which will bring any ab-seeking efforts of yours screeching to a halt.

Many bars—like the offerings from ONE or thinkThin—only have 1 gram of sugar for 20 grams of protein (and still taste delicious, to boot).
