Warm up!

Perform a Warm-Up Before Your Workout
For most people, 5-10 minutes of low-to-moderate intensity cardio activity is enough. The warm-up helps you transition from rest to movement, gradually increasing body temperature, heart rate, and blood pressure to support the physiologic challenge of the vigorous workout ahead. A proper warm-up also reduce risk of injury, helps reduce post-exercise muscle stiffness and improves exercise performance.
