Well I've got 2 in a row in. 25 minutes(omg I couldn't make 30, first time I can ever remember stopping early) it was tough and boring but when isn't it? Well actually my 2nd one was easy... why is that. Actually I know why... I waited the fatigue off... now if I just had that magic bullet for the fatigue and stiffness to make every one easy... errr NSD!!!
