I blacked out while doing packing stretches seated at my computer. I would pack, hold for 10 seconds, then relax before attempting another. On the next attempt, I would increase the number of packs. Well, on my last one, I did THIRTY packs, relaxed into the hold...and came to on my side, lying on the floor. Whoops! The point is, with a black out during dry training, you WILL come around, it may just take a few minutes. Since then, as Mandy recommended (and does herself), I do my packing stretches LYING DOWN.
