I've been running stairs for the past few months. 7 - 10 repeats sprinting up and walking down. At first my muscles felt like jelly but after a few sessions, started to feel good.
I actually felt pretty good about my progress it until I saw this Ultimate Stair Workout. There are no words to describe the sheer pain that resulted the first time I tried a full set. Three sets? OMG...NO! But it's set to a great tune,AC/DC's Thunderstruck. That helps...for a minute!
Anyway, time to get back at it. Who's up for a challenge? Until next time... ThatRunninGuy
