☑️The Right Position: In order to perfect the plank position, think of it like a push up, except in the push up the weight does not fall onto the abs alone, it also falls onto the chest and the triceps. With the plank position, there is no involvement of the triceps or the chest and it is the abs bearing all the strain.
☑️The Right Arms: Make sure your arms are right beneath the shoulder, absolutely in line with the wrists. Make sure you do not hunch your shoulders pushing them forward to your ears. Keep them straight and erect so that the rest of the body pose is in line with the shoulders.
☑️The Right Line: It is very important to get the alignment right. Just like a plank, your alignment must be straight and solid. Keep your neck long and try keeping a distance of at least 6 inches between the chest and the chin. In order to align the spine with the head, just look a few inches further from where your wrists are resting and you will acquire the perfect alignment for your perfect plank.
☑️Keep Straight: If you are looking for flat abs with the help of the plank, make sure you keep your back flat, throughout. If you keep your back flat the whole time, the transverse abdominis, the deepest layer of the abdominal will be immersed in the exercise till the very end, holding the spine and holding your position stiff and solid, just like a perfect plank. If you end up lifting your hips or dropping them, the abdominals engagement will minimize and the plank will be far from perfection. Do not do that.
☑️The Right Hips: A drop or lift in the hips can put a lot of pressure on the back and lead to injury. the idea is to keep the spine in line at all times so that the body is as stiff as a plank gets for maximum effectiveness.
