Staring at a Concrete Wall
The mistake: Instead of watching yourself in the mirror, you like to zone out as you race through sets.

The issue: With the rise of the super-minimalist, industrial-chic—or just industrial—gyms, mirrors can be hard to find. Even in gyms where mirrors line every wall, some people find them distracting, so they don't use them. A mirror, though, can be a great way to keep an eye on your form, says Wright, and can help you make sure you're doing an exercise correctly 100 percent of the time.

The fix: Use the mirror, especially when you're doing technical moves like power cleans, deadlifts or even squats (so basic, yet so easy to do incorrectly).
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
