I couldn’t leave my building today so I resorted to stair climbing (I live on the 10th floor).
FWIW I still prefer running outdoors (wind, fresh air, birds, other runners and yogis…), but apparently stair climbing is more effective to burn calories, even more if you take 2 steps at a time.
If you do both, is there any proportion that works best for you? like 2 days running and one day stair climbing? alternating days?
Any drawback doing too much stair climbing?
If you do it before running, your muscles can be over-stressed at the start of a run, increasing risk of impact injuries. So make sure to give yourself recovery time after stairs before you do a hard run again.
Done in this way, you can build up your support muscles which will actually decrease the risk of running injuries.
