A leg press is a machine used in strength or resistance training. It requires a person to push weight away therefore engaging their leg muscles. But when the woman she is halfway through her second repetition, having already lifted the weight, she relaxes her leg while it is extended, rather than keeping her knee bent to support the weight.
