Can someone explain to me how the "# Reps Actual Weight" thing works? Are there any good rule of thumbs to remember when determing the amount of weight one should use?
The way your program breaks down it gives the recommended reps and allows you to record the weight you use and the actual number of reps you performed. As a general rule if you can lift a weight the required number of reps with ease you should up the weight. Another rule is a 2x2 rule. If you can perform 2 reps above your requirement for 2 consecutive sets, add weight. Regardless, your last 1-2 reps of your last set should require your maximum effort (and then some). Remember to warm up on your first set and then load em up and go for it.
