U is for upright Rows.

The upright row is considered one of the best muscle builders for the back and shoulders! Get your posture right using these tips:

• Start standing tall you’re your feet shoulder width apart.
• Start with the barbell (or a household mop/broom or and weights you have at home) at waist height.
• Keep your back straight and lift the bar to your chin, keeping the bar as close to your body as possible.
• Keep your elbows above your forearms the entire time. Hold for a moment, then slowly lower the bar.

Repeat.
