When we talk about strength training for abs, we are really talking about using strength training for fat loss. Lets face it–we all have abs, we just need to achieve a low level of body fat to reveal them! And in order to lose fat, you must be conscious of the food you put into your mouth. Put simply, a low-carb/high protein diet that is not excessive in calories is what will work for you. Remember, there is no such thing as spot reduction. Building muscle is important for fat loss because muscle is metabolically active tissue! In other words, muscle is the physical place where body fat is burned.
FAT LOSS IS A 2 STEP PROCESS:
Step 1: The body must release the stored fat from the adipose tissue. In order to do this you must keep your insulin levels low (eating low carb) because, when insulin (a storage hormone) levels are raised, your body cuts back on producing glucagon, which is the hormone that is responsible for allowing your body to release stored body fat!
Step 2: The fat is then sent into the muscle tissue to be burned as energy (i.e. fuel).
With the above information in mind, you now have a clear understanding of how building a “bigger engine” (building lean muscle mass) can help you more effectively burn fat, which will help you get better abs! When it comes to fat loss, you want to be the opposite of your car–you want to have a “bigger engine” (i.e. more lean muscle mass) that is “gas inefficient” so that you burn as much fuel (stored fat) as possible to keep your body running!
The more muscle you have, the faster your metabolism is – not just when you are training, but even when you are sleeping.
