The vastus are those muscles that are located further to the side and on the inner part of the thigh, closer to the knees.”

Are there any errors when using the extension chair?

Even though it is an extremely simple piece of equipment, given that it is a chair with a low complexity movement, there are still many bodybuilders, whether beginners, intermediate or advanced, who end up making some mistakes, which are harmful to exercise and muscle health.

Lack of anatomical adjustment for each person, after all, each person has a physical structure in relation to height, whether short or tall. Therefore, when the student sits on the chair, places the load and does not adjust it properly, difficulty is noticed when performing the movement, losing amplitude, reducing strength gain and muscle hypertrophy.

Chair adjustment is essential for the effectiveness of the movement. When placing the chair too far back or forward, the knees become misaligned with the central axis of the equipment, hindering movement.

“Imagine that our knees have to be in a straight line with the axis of the machine, so our thighs have to rest on the chair with the back of our knees well supported, not too far forward”, he explains.

Another mistake is regarding the foot support, that is, the bottom cushion. “The correct thing to do is to stay in the crook of our ankle, at the beginning of our leg, it can’t touch too much on the feet or too much on the leg , it needs to be in the crook of the ankle.”

And you cannot leave out two classic mistakes in any exercise, including the extension chair: using too much weight and poor posture. Therefore, always respect your limit, do it slowly and keep your body on the bench when moving the machine, okay?

It is possible to vary the exercise on the extension chair, with the traditional way being more common, which is when both legs are used on the equipment, making the movement of extending and flexing the knees, making it possible to include other variations based on the student needs and limitations.

Among some strategies to improve performance during training, there are other methods, such as the drop-set, widely used to intensify training and do the series until concentric failure, or bi-set, which is when the student performs two exercises in a row. for the muscle group being worked.

For those who want to increase strength gains and muscle hypertrophy, the rest-pause method may be an option. This is because it is a training strategy that requires the student to perform the indicated number of repetitions and, consequently, a short pause (usually 10 seconds) before returning to the movement.
