A new study finds that from 1990 to 2007, nearly a million Americans wound up in emergency rooms with weight-training injuries, and that annual injuries increased more than 48 percent in that period.

Women were more likely to injure their feet and legs, while men’s injuries were more common in the trunk and hands; men had more sprains and strains, and women had more fractures.

Overexertion, muscle pulls and loss of balance accounted for about 14 percent of emergency room visits. More than 90 percent of the injuries occurred while using free weights rather than weight machines.22weight_stat-popup
