The planks can be performed as a classic strength move from short and static to minutes-long and dynamic.
The benefits of the plank, as the ultimate full-body pose, can be seen in toning your abs, legs, back, butt, and arms and improving your posture and stability. The planks are excellent when are combined with other strength exercises.

Unlike crunches, which are more common in abs workouts, the plank is a static exercise. However, this fact does not make it easier. What is more, the plank involves the work of a lot more muscles. The main emphasis is still on the upper torso. The so-called corset muscles are largely exerted when you are standing in the plank position.

It might seem to be easy but, trust us, this single exercise will make you sweat harder than a hundred crunches. The thing is that your muscles are always tense during a static workout. This way they will become stronger in a shorter period of time. Now let’s get down to the deal. Today we want to challenge you.
