I usually start doing 8 with a easy weight and then drop down to one ware I can do roughly 7/8 and on my last set I max out, I have been considering raising my reps but as I have only just started this new routine from doing a bulk with very low reps and high weight I’m thinking it may be a better idea to gradually raise my reps????
Chris, since nobody answered your question, I did a little research on the subject and couldn't find an immediate answer. What I did find was that people stress change and variety in their workouts because light and heavy weights work together. Heavy weight gives your muscles the strength to lift weights that you ordnarily thought that you could not. Light weight, on the other hand w/ high reps, gives you the endurance to lift the heavier weight w/ more repetitions, thus making you stronger. I have attached a link to a site that you can check out. Good luck!
