This is the stairs I have been talking about :-) It looks easy but it is hard! First time I tried it I managed 250 on level 3 including pause every 50 step,- today I did 500 without brakes! 340 on level 4 and 160 on level 3 :-)
I also did the rest of the program,- without heartflicker!!! Yeah!
Now I have made a page on Facebook, maybe you will like it to follow me? It is called Maisens corner (like the blog) and I have shared all my training chapters in it.
Wishing everyone a nice day :-)
