Context: Gym workout day today . I used the rower for only the second time ever as it 's been one of those things I just consider a bit too scary but it was actually fun in a kind of a way and very challenging . I managed to knock about a minute off the time for 1000 m from the one and only other time I 'd used it so at least I can see I ' m inproving in my fitness . I discovered my biceps last night too .
