Women are hitting the weight room in record numbers, and a new study found that weight-training injuries among women have jumped a whopping 63 percent. Here are the most common slipups and how to fix them, so you leave the gym strutting — not limping.

The mistake: skipping your warm-up

You wouldn’t launch into an all-out sprint the second you stepped onto a treadmill, so you shouldn’t jump right into deadlifts the instant you hit the weight room. “Working cold, stiff muscles can lead to sprains and tears,” says Morey Kolber, Ph.D., a professor of physical therapy at Nova Southeastern University in Florida. “Warming up increases circulation and improves range of motion, which preps your muscles and joints for action.”

The fix: “While opinions about static stretching may differ, a dynamic warm-up can decrease your risk for injury,” says exercise physiologist Marco Borges, author of Power Moves. After five to 10 minutes of walking or jogging, do 10 to 12 lunges and pushups (the bent-knee version is fine) before starting your routine.
