Fadi,
I'm very interested in this table, but find it hard to translate it into practical benefit for me because I'm unaware of which type of muscle fiber is relevant to each bodypart.
Apologies if you already covered this and I missed it, but is it the case that each muscle (eg. quads/pecs/traps etc) is made up of all 3 fiber types?
Is it too simplistic for me to try and say "ok for squats I should refer to X fiber type in the chart and do that amount of reps, and then for chest dips I should refer to Y fiber type..."?
I have a feeling that it's probably not that easy, but if that is the case I'm interested in your views on any particular body parts, or exercises, you think should get higher/lower rep range. I recall you said you got gains in squats and seated row when you increased reps. I tend to go 8-10 reps for most exercises, but around 5-6 for deadlifts, maybe 15-16 for lateral raises.
