Finally got my stallbars and am able to follow the TB series better.
I feel my lower back at the end of the series when performing the walk - but not in a "pain feeling" but more a "tired felling" - is that ok or should i feel nothing in my lower back? I guess the angle of the video ist not really a big help. The series is tons of fun and i am amazed at how much better i got in only 4 weeks!
