I hate high reps. The training that is most enjoyable for me is working up to heavy doubles and singles with long rest periods. I do some high rep work though because I think I need longer time under tension for hypertrophy. Also extend sets with slower reps, drop sets, etc. at times.
Here's something weird, and I'm wondering how many others experience this: often my joints act up more with high reps on certain exercises.
If you're doing 6 and 7 exercises I don't see where you can go to change things up. For instance, if my program includes incline db curls and standing db curls for biceps, I could change that up with Scott curls and whatever else down the road. How do you change things up if you're doing a half dozen exercises or more from the get go? It's another argument for low to moderate volume vs high volume IMO.
