Physical Preparation for my Mt Kinabalu Summit Climb.
Although you do not need to be super fit, you do need to be in good physical condition.
Here are some suggestions from the Alpine Guides Association:
A good amount of outdoor cardiovascular exercise (power walking, cycling, running, mountain biking etc) and getting out for long days in the hills whenever possible is great preparation for your climb.
Fitness training should begin 2-3 months leading up to your trip
We recommend all climbers take cardiovascular sports at least twice a week, with each session being a minimum of 2 hours in duration at a medium intensity.
Fitness training should begin 2-3 months leading up to your trip, this way you should be well prepared. Ensure you are medically fit too.
