Here is the deal. I recently modified my work out a bit to mix things up and keep things changing and fresh after about 2 months of the same. The change was to drop a few iso exercises and focus more on compounds. I also dropped to only doing two sets of about 6-8 difficult levels of weight. Difficult to the point where at the end of the set I can't do another rep. However, I was wondering if this was a good way to go about gaining muscle and strength. I've seen many exercise routines with as many as 5 sets, or some with 3. The reason I'm trying 2 is because I believe the MAX OT routine had a few weeks set to only 2 sets. Really I wasn't sure what way to go, but I wanted to check to make sure I'm not making a misinformed mistake with the change I made.
