How fit do I need to be to do this trek? - Day

Your physical condition needs to be stable as you will be trekking in thin air. With a good physical condition, you will be able to metabolize better. With your body in a fit condition, you can cut effects such as Mountain Sickness, Respiratory problems, digestion problems and other problems you will face.

To improve your cardiovascular fitness, high-intensity training works best. High intensity training involves short bursts of high-intensity effort, followed by a recovery period. It is the best way to increase your stamina and prepare you for trekking at different altitudes.
