Here's this week's exercise:

Alternating bent-over row: Sometimes it can feel like one side of your body is killing every workout while the other side is on autopilot.

Well, that's not all in your head: Just like most people favor either their right or left hand, you can develop a dominant side of your body, too.

Alternating moves like this one help even the playing field. By rowing each arm separately, you're combating muscle imbalances and upping the challenge for your core.
