Also, sorry to ask but could you give me an idea how to start with the 5x5 programming? I generally understand that once I hit 5x5 reps I up the weight 5kgs for lower, 2.5 kgs for upper exercises, but I'm not sure were to start at and how much to drop the weight by for 'moderate days'. I guess it would be a case of trial and error.
Also, what would you perscribe rest wise between sets? 3-5 mins or less?
