Cardio-vascular Training
Intensive cardio-vascular training is given to the driver for creating physical endurance. They have activities like running, swimming, cycling or even roller-blading. Neck and chest muscles of the driver need to withstand extreme pressure. Usual gym equipment is not fully able to develop the muscles needed.
