I do sorta understand how you feel, though. I'm a guy with big legs and I've always felt weird about it until I realized most girls like them and most guys wish to have legs like me. But for me, I had "tree trunk legs" before weightlifting. I think it's mostly genetic.
For muscle fiber type, there's fast twitch (Type 2) and slow twitch muscle fibers. Slow twitch is for endurance, or Type 1. Fast twitch is for strength/power. There's actually a few different fast twitch types that I don't recall what each their purpose is. Anyway, generally people slow twitch dominant go into endurance running, triathlon, etc, type of sports. One "test" I've heard for if you're fast twitch dominant is if you have giant calf muscles without working out (because calves get worked by walking,) which I had. So there's muscle fiber types. It's a bit paradoxical, but Type II will bulk up easier to a point, but your body has more Type 1 muscle fibers. Bodybuilders usually work to develop the Type 1 fibers by doing 8-12 reps per set.
Anyway, as far as training goes, yeah, pretty much nobody can give anyone a conclusive answer about training unless they know you very well and your exact goals. And then they can be wrong. As far as my personal opinion, I think much too much emphasis is placed on muscles. The main deciding factor in anything athletic is your brain's ability to fire muscle fibers and then your connective tissue strength. If you've heard stories of a mother lifting a car off a child or something like that, it's an example. The reason the brain won't let you just lift cars all the time when not in an emergency is because it's stressful to the body to do that and generally untrained you'll blow your connective tissues/joints/muscles out in the process. So I think in this regard, power production is more like training for a skill. I think whatever happens to the muscles is secondary to what happens in the brain/nervous system.
Anyway, for the reps/sets thing. I like working with heavier weights and fewer reps, and across the board that seems to be the consensus among strength coaches, to have people in weight classed sports do fewer reps/sets, and work with higher intensity, with the science being the muscle fiber thing above. The only caveat is, when you work closer to your 1RM, your movements slow down, and obviously doing slow movements doesn't help much in athletics. Obviously the less weight used for whatever will allow you to move faster. So you have to find a balance, as power scientifically is {(Force × Distance) ÷ Time} Now I like doing around 5 sets of 5 with whatever movement, at around 70% of my 1rm (I used to like 1-3 rep sets at 80-90+% of 1rm.)
Also, unless you're limited by money/time, try to get more ice time. It's cardio and obviously you're training to skate better, right?
