In terms of physical fitness, for a tourist opting for strenuous trekking, it is advised to receive physical fitness and technical training beforehand. For smooth, moderate, and challenging treks, professional training is not a compulsion, but it always better to remain fit. You can prepare yourself for the trek by doing some exercises like running, jogging, or swimming regularly from the month before your trek. For gears and other equipment, you need not worry. The travel agency will manage all the necessary gear and equipment for you at your cost.
