My office is at the 9th floor. While everyone uses the elevator, I thought of using the stars instead.

Is it a healthy choice to climb up 9 storeys everyday with the following conditions?

• Each floor is around 4.5 m tall (~15 ft)
• I carry a backpack of around 7 kg (~15 lbs)
• Only once in the morning

Is this good for health or would it deteriorate the bones in the long term?

With the following assumptions:

• Average healthy male
• No history of bone injuries or breathing difficulties

Is this good for health or would it deteriorate the bones in the long term?

Is there any study stating walking upstairs can lead to bone/cartilage deterioration for an average person?
