Cadeira flexora — Análise de Técnica

Using Excessive Momentum

Jerking the weight up or allowing it to drop quickly on the eccentric phase reduces muscle tension and engagement. This can also place undue stress on the knee joint and lower back, increasing the risk of strain or injury due to uncontrolled forces.

Lifting Hips Off the Pad

Allowing the hips to lift off the bench during the curl indicates that the weight is too heavy or the core is not engaged. This shifts the load from the hamstrings to the lower back and hip flexors, reducing hamstring isolation and potentially causing lower back discomfort or injury.

Incomplete Range of Motion

Not fully extending the legs at the start or not fully contracting the hamstrings by bringing the heels close to the glutes limits the muscle's work. This reduces the effectiveness of the exercise, preventing full hamstring development and strength gains.
