Warming up of muscles is very important for ensuring that the body is ready for weights and exercises and to prevent injuries by reducing stiffness of the body.
Spine twist is a good way to flex and warm the back, waist and abs muscles. Spine Twist also adds strength to lower back muscles.
Stand with a feet distance apart and hand stretched out. Twist till you reach the maximum on one side, repeat with other side.
Exercise with caution if you suffer from or have had back injury.
