Even if you don’t have much time to work out, you should never skip your warm-up.

The American Council on Exercise explains that a good warm-up:

• Boosts your body temperature to help your body burn calories more efficiently.
• Helps your muscles contract more forcefully and quickly while improving elasticity, which reduces injuries.
• Helps deliver oxygen to your muscles more quickly by raising your metabolic rate.
• Improves muscle control and range of motion.
• Helps you enjoy a longer workout by easing the adjustment to exercise and prohibiting lactic acid from accumulating in your blood.
• Improves your focus and helps you mentally handle your workout.
