Performing a chest press

Relaxing the legs

Do not repeat while slipping out of the pads on the decline; establish foot support before taking the weights.

Moving dumbbells over the face

Do not lower uncontrollably across your face; follow the safe path beside your ears.

Flaring the elbows

Do not spread your upper arms as the weights lower; maintain a comfortable, fixed width.

Collapsing the wrists

Do not let the handles fall backward from your fingers; align your hands with your forearms.

Fast lockout

Do not snap your elbows straight and jar the joints; extend with triceps control and pause briefly.
