Every person hitting the gym for an exhaustive workout has the goal of getting into 6 pack Abs or flaunting one.
The Human body has well toned muscles, however, it’s the layer of fat which causes the muscles to hide. Thus fat loss is the biggest concern. Daily diet contributes to 70% and workout contributes to about 30% towards your fitness.
What you eat in 23 hours is more important than banking on that 1 hour spent for a workout. Having said that the role of diet is very clear, however your workout is also an important aspect as 30% missing cannot complete 100% fitness goal.
