    I was always a sprinter as far back as I could remember, and sucked at long distance running. Now as an adult I took a DNA ancestry test, and among other things it told me, just as I suspected, that I'm fast-twitch dominant.

    Me too, I have 2 copies of the fast twitch gene, but it hasn't helped me run fast, and if I were to choose one type of running that I think I'm best at I would've picked long distance. However, if I do exert maximum force my muscles do tend to fatigue quicker than most other people's. I don't know what to believe TBH.

    *I have a question*, lets say you have been doing slow reps since you started or genetically speaking its possible you have more slow twitch fibers by default. You want to hit the type 2 a and x fibers with fast reps but they are less conditioned as a result of your training and/or genetics. If my understanding is correct then your ability to lift more weight is more dependent on your slow twitch muscles as they make up an unusually large amount of your power out put and thus you have a hard time lifting heavier weights fast in order to hit the other types. Like I said I'm not sure if the assumption of mine is correct but if this is why I have a hard time doing fast reps at heavy weights can I hit the type 2 muscles fibers better if I take the weight down bunch more notches and lift it faster? If not how can I get fix this? Perhaps its in my head, I just want the most I can get.

    Robert Dicke lift moderately heavy with compound lifts short recoveries your tempo should not be fast but at a constant fluid motion while performing the exercise 8-12 reps 60-80% of how much you can lift is good start then try and go for 12-15 reps after a couple of weeks. Learn sprinting drills and techniques start incorporating them into your cardio routine hope this helps

    Robert Dicke and one more thing, if you cannot perform compound lifts with good form you may suffer muscle imbalances and still may need a trainer to aide in instructing some corrective exercises not to mention foam rolling, stretching and knowing how and when to start and stop your deloads

    Regarding the size principle: are the muscle fiber types recruited according to load (force) or to effort? If you hold a light weight in an isometric contraction, it gets harder and harder as time goes on-your effort increases even though the load stays the same. As you approach failure you end up recruiting all muscle fiber types. You drop the weight once all fibers are fatigued.
