Curl martillo — Análisis de Técnica

Using Momentum (Swinging)

Swinging the dumbbells by leaning back or using hip drive reduces the tension on the target muscles (brachialis, brachioradialis, biceps) and shifts the load to the lower back and shoulders. This decreases exercise effectiveness and increases the risk of lower back strain.

Incomplete Range of Motion

Not fully extending the arms at the bottom or not fully flexing the elbows at the top limits muscle activation and growth potential. Partial reps do not provide the full stretch and contraction necessary for optimal development of the brachialis and brachioradialis.

Flaring Elbows Outwards

Allowing the elbows to move away from the body, especially during the concentric phase, shifts emphasis away from the brachialis and brachioradialis and can place undue stress on the shoulder joint. It also reduces the isolation of the target muscles.
