You will be climbing a major mountain and you are strongly advised to be in a physically fit condition. Here are some suggestions from the Alpine Guides Association

“The best preparation for mountain sports always involves good amount of cardiovascular exercise outdoors (running, cycling, mountain biking etc) and getting out for long days in the hills whenever possible.

If you do the amounts of regular weekly cardiovascular exercise indicated on the fitness level for your course during the 2-3 months leading up to your trip, you should be reasonably well prepared. Don’t forget to read the trip descriptions / itinerary carefully to find out what else is involved too, so you can tailor your preparation accordingly.”

X-Trekkers recommends all customers to engage in cardiovascular sports at least 2 twice a week, with each session being a minimum of 2 hours in duration. The exercise program should commence at least 2 months before you start your Mt Kinabalu adventure.
