Your Modal Madness lessons are a great way to challenge AP skills while building fretboard knowledge of the modes at the same time. I've been working with these for quite a few months now as a part of my warmup and workout routines. One thing that I noticed is that because of the length of these constant speed runs, my right hand, even though it can start out very relaxed, ends up getting kind of tight towards the end of the run.
My question to you is should I stop playing when it starts to tense up, or is it ok to allow some tension in the right hand due to the length of the run. I'm wondering how you approach speed building with these scales. Should I focus first on relaxation, or is it better to play it through to the end focusing on maintaining accuracy even if under tension? If I allow myself to play under tension, I'm thinking I could be doing one of two things 1) developing strength and stamina, or 2) reinforceing bad habits. If I focus on relaxation, I'm thinking that I may not be pushing my limits enough.
