Happy cos I was able to run for around 12 minutes with 1.5-min brisk walks in between (4.5 km/hr speed and level 1 incline). For a physically unhealthy and unfit me, this is an achievement. I could not even walk before for more than 10 min at a 2.5 km/hr speed and 0 incline. I will get to that 6 km/hr and level 3 soon!!!
