I did do my morning sports and now I feel fresh like Hulk!!!!
Details: due to hospital regulations I am not supposed to leave the house. They told me to use their 6 Staircases for my workout. My routine is: walk down 4 stories in 90 seconds, run up same in 30 seconds. Repeat, pause for ten minutes, repeat. Half an hour of that is as good as an hour worth of light jogging, quite possibly two hours. Check details on HIIT via Google search.
