Have any of you guys tried testing how many reps you can do at 80% of your max, like Doc suggests in the "Finding the ideal training split article"? I'm just curious to see if you had any interesting results, like a big difference between different muscles. I could definitely see some people having the same results throughout but I'm sure some people are anomalies, which makes them very well suited for certain sports.
I've tested my upper back, lats, shoulders, biceps and triceps and I got the same result with all of them. I'm going to test the chest, abs, and lower body soon. Any thoughts from you guys?
