Did you know that more effort works better than less effort?

Makes sense, it's a much more "intense" activity than just walking on flat ground

What's the best exercise?

The ones you can keep doing.

Relevant info: 5 flights of stairs per day.

A study that analysed comprehensive data from the UK Biobank that concerned the health and lifestyle facts around four hundred and fifty eight thousand adults found that even five climbed flights of stairs a day had deep impacts in the health. Regular stair climbing was found to lower heart disease risk by almost twenty per cent when followed up on for just over twelve-and-a-half-years.

Yes, that's why the stair master exists
