Anyone do this?
Apart from leg work where I pyramid up, after a brief warm up with a very light weight and lots of repetitions, I usually start at the heaviest weight I can do for between 6 to 8 repetitions on and then drop the weight down to maintain the rep count. If I can do more than 8, then I up the weight. If I do less than 6, then I drop the weight down a bit. Incidentally, the only other exception to this is when I'm training smaller muscle groups such as arms, abs and calves. Then I use a higher rep count of between 8 to 12 (arms), 12 to 20 (calves) and 25 to 30 (abs).
