Today were doing timed exercises. The good thing about this is you don't have to count them. This cuts out the psychological stepping stone of wanting to stop at 10 or 20 or 100 or whatever. So just watch the clock and keep pushing. Resist the urge to count and think about something else like what wuss you used to be back when you didn't work out.
